How to make a speaker crossover?

Can someone please teach me how to make a speaker crossover for the bass, midrange and treble?


Or for a passive crossover:

http://sound.westhost.com/lr-passive.htm

Basically you decide what kind of filter you want then buy appropriate inductor and capacitor combinations to either pass high frequencies or low frequencies (based on the impedance of the driver). The midrange crossover is just a lowpass and highpass filter combined.


Here you go, seems to be all you'd need to know how.

http://www.snippets.org/filters/crossover.htm

What does the corner frequency for a speaker crossover network represent, and how do you calculate it?

I built a simple crossover network using just an inductor as a lowpass filter an just a capacitor as a high-pass filter for an electronics class. (Then hooked up to a woofer and a tweeter) I have all the data pertaining to the circuit, including graphs of the transfer function versus frequency, but now I need to calculate the corner frequency observed in the network we built, then calculate the values of the capacitor and inductor needed to make a crossover network with a corner frequency of 1 kHz for both speakers. Problem is, I have absolutely no idea what a "corner frequency" is, so any help would be appreciated.


On a low pass filter, the corner frequency is the frequency at which the output power drops 3dB from the dc point. This corresponds to the point where the output voltage decreases by 30% (or, more accurately, where it drops to 1/sqrt(2) of the dc value). So, if you already have measured the output voltage over frequency (with a constant amplitude input voltage), then just find the frequency at which the output voltage drops 30%.
Do the same for your high pass, only this time find the point at which the voltage is 30% less than the high frequency 'flat' portion.
If you designed your speaker network correctly, both the low pass and high pass would have the same crossover frequency.

How do you hook up a a speaker crossover?

I have these speakers http://www.procarsound.com/catalog/images/B0009K67P8.01-AIWHEFKG4HT6N._SCLZZZZZZZ_.jpg and I was wondering do I just insert the wire into the openings for tweeters, woofers, and input or do I need to buy I connector to crimp onto the end of the wires first?


You just run speaker cable from the amplifier to the input, and then run speaker cable from the tweeter outputs to the tweeter and from the woofer outputs to the woofer. You don't need to crimp anything on; you can just screw bare wire into the set screws.


i would go to the store and get some male U crimps to lower noise resistance but it dont really matter man

How do you fix a crossover that has come off the speaker?

I've got two Infinity 693.9i 6x9 speakers. One of them had the crossover come off because the amp was not secured down well enough. I'm guessing I can solder it but I've only done that a few times and I don't want to damage the actual speaker. So what should I do?


If the wiring has come disconnected, you will need to solder it back together. If the mount itself is broken, maybe you can use a hot glue gun to reattach it. If you are uncomfortable with soldering, a car stereo shop would probably do it for a small fee.

Looking for the Speaker Crossover Frequency for the Technics SB-CR77 3-way Floorspeakers?



Ask Parts Express (if you want info on what new/replacement crossover to get)...

Just some info for you in the meantime, if it is a 3-way speaker system, you will need two crossover frequencies because there will be two crossover points: one, between the woofer and the midrange driver; and the other one, between the tweeter and the midrange driver.

I cannot find much more on the SB-CR77 than what's above, but it probably is similar to the current model 12" 3-way SB-LX70K. The crossover points of this speaker system are 3,000 Hz and 6,000 Hz...

According to the information that I found on the CR77, it is a 2-way speaker system with a 12" woofer and a 2" tweeter. For a speaker system from Technics of this type, look for the crossover point to be around 3,000 Hz. Usually, it says crossover point (along with the power handling and the nominal impedance rating) on the back of the speaker.

Amazon has some Technic models to find out if they are similar to yours as a reference...

Happy listening!

component speakers vs. a 2way or 3way speaker with a tweeter and crossover.?

I have (3) 12'' Kicker cvr subs and will be powering them around 1000watts rms total. I need speakers that are loud and will sound good. Components I know sound great, but would my speakers sound better if I have my 3way 5 1/4 speaker down low and a separate tweeter on the upper door panel? I can get tweeters separate with crossover cheap and it would be alot cheaper to do things this way. Would it sound better or just be a waste? I havent decided the brand yet. MB Qaurt, infinity, or alpine. I am also running 6.5'' in the rear


Having the tweets apart from the speaker is my preferred choice as the sound is more dispersed.

If your total system power is 1000 watts RMS or more, you will need to:

1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle battery
3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 1/0 AWG wire.

Failure to do this will result in you replacing them anyway as the alternator will eventually fail.

Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php?file=6d26c621

What is the advantage of component speakers with crossover compared to regular amped speakers?

Im looking to upgrade the speakers in my 06 equinox and can't decide which way to go? also what does the crossover do? and do i still need to amp them?


Crossovers act something like a sorting station for the different frequencies produced in music. With crossovers, only certain ranges of frequencies are allowed for the speakers to play and others are blocked off. Low frequencies 100 Hz and lower, go to sub-woofers. Midbass speakers receive frequencies between 100 and 250 Hz.
Midrange speakers receive frequencies between 250 and 3,000 Hz. And all frequencies above 3,000 are handled by the tweeters. This is simply an reference point and not all crossovers are set to the same frequencies.

There are also two types of crossovers, a passive and active. Passive crossovers are inexpensive and easy to install, and doesn't require any connection to the battery. However they are not efficient in their job. Active crossovers are usually more expensive, and harder to install. However they allow for adjustment of the sound and are very effecient.

You will need to amp the passive crossovers. However the active crossovers will require a powersource from the automobile's battery so will not need to be amped.

The choice is fully up to you. If you have the money, you should always go with the better choice.

WHAT purpose does A SPEAKER CROSSOVER serve?



IN A SPEAKER BOX THERE IS USALLY THREE SPEAKERS. THE CROSSOVER DIVIDES THE SOUND AND SENDS THE HIGH RANGED SOUND TO THE "TWEETER" (THE SMALLEST SPEAKER), THE MIDDLE TONES TO THE "MIDRANGE" (THE MEDIUM SPEAKER), AND THE LOW TONES/BASS TO THE "WOOFER" (THE LARGEST SPEAKER ON THE BOTTEM)

ALSO, THERE IS ALSO LOW PASS FILTERS AND HIGH PASS FILTERS ON CAR STEREOS. THIS WORKS LIKE A CROSSOVER BUT INSTEAD BLOCKS THE LOW TONES ON A HIGH PASS AND THE HIGH TONES ON A LOW PASS.

component speaker w/ crossover or coaxial speakers?

Which produces better sound quality? a component speaker w/ crossover or the coaxial speakers ( 2-way)


Coaxial speakers do have a measurably broader sound dispersion and in theory they should have better sound. The only problem I have is that the speakers that sound best to me are component speakers. I wouldn't let any one else tell me which speakers are best. The best speakers for you are the speakers that sound best to you!

home theater (crossover freq, decibel, speaker size and speaker distance) setting?

I have a Onkyo HTS-590S home theater
front: 3-1/8" Cone (Woofer), 3/4" Ceramic (Tweeter)
center: 3-1/8" Cone (Woofer) × 2, 3/4" Ceramic (Tweeter)
surround: 3-1/8" Cone (Woofer), 3/4" Ceramic (Tweeter)
passive sub: 8" (20 cm) Cone
units reference -- 3-1/8" = 8cm, 3/4" = 2cm

1) what crossover freq should i set for best audio. i have options 40hz , 50hz, 60hz, 100hz etc..is lower the better?

2) what decibel should i specify for front, center, subwoofer and surround. the amp gives me choice from -12db to +12db. is higher the better ?

3) when asked to choose the speaker size , i am not sure whether to choose small or large for the center, front and surround, i know that the subwoofer is large.

4) i have measured the distance from my seating position and set
front 8 ft ,center 7ft , surround 7ft , woofer 10ft
should i specify the exact distance or should i specify a couple of feet more so that the amp outputs more power assuming the speakers are far


All of the above advice is on the mark. It is very important to set your front speakers to "small". This way, low frequency sounds that would ordinarily go to the front only will also go to the sub. In Dolby Surround, the subwoofer is used as an "LFE" channel mainly: LFE means low-frequency-effects, usually low rumbles from explosions, etc. It does not mean ordinary bass from music. That is sent to the front speakers unless you select "small". Your front speakers are not large enough to handle that alone.

Paradigm Reference Studio 60 v.5 loudspeaker By Kalman Rubinson • November, 2009 Stereophile Magazine
I have reviewed and owned so many Paradigm speakers that they feel almost like members of the family. I've owned the v.2 and v.3 versions of the Reference Studio 60, and reviewed the v.3 version in Stereophile (in December 2004 , Vol.27 No.12). My long and intimate relationship with this speaker is founded on the best of reasons: We are extremely compatible. The Studio 60, in all its incarnations, is large enough to be used as a full-range speaker with nearly any program material, and yet is compact enough to be easily accommodated in my relatively small Connecticut listening room. It neither looms over me nor disappears into the space. Used as a center-channel speaker, it's just short enough to clear my line of sight to the video display. Finally, and despite inevitable price creep over the last decade, the Studio 60 still comes in under $2000/pair—my line in the sand for a reasonably priced system.

Join the family
Unpacked and set up next to my Studio 60 v.3s, the Reference Studio 60 v.5s were much more attractive in finish and more shapely in design, though clearly (once I'd removed their grilles) based on the same DNA. In each, the dome tweeter sits in a cowl fitted to the top of the cabinet. All drivers and the front port are supported by heavy frames resiliently mounted to the front panel. (Paradigm calls this system IMS/Shock-Mounting.) Both models have cast-metal front bases with feet that match the cast feet in the rear. Finally, the upper cone driver, a mid-woofer in each case, differs in cone material from the woofers proper, and sports a brass dome or phase plug. As in the prior models, the dedicated woofers of the v.5 have mineral-filled polypropylene cones, but the v.5's mid-woofer is made of Paradigm's Satin-Anodized Pure-Aluminum (S-PAL), the dome tweeter of Gold-Anodized Pure-Aluminum (G-PAL).

Despite these similarities, the v.5 is a much greater leap forward than any earlier Studio 60. Gone are the slab sides, replaced by curved panels that converge at the back. This not only contributes greatly to the speaker's appearance, it also increases the rigidity of the cabinet without increasing its mass; the new cabinet was satisfyingly free from noticeable vibrations. Equally notable is the change from the 7" midwoofer and 7" woofer pair to three 5.5" drivers. While this retains roughly the same total radiating surface in the bass, it significantly reduces the radiating surface at the crossover to the tweeter, affording a wider horizontal radiation pattern where it is most needed.

Still, I was initially disappointed in the Reference Studio 60 v.5 in two ways that may ultimately prove inconsequential. First, the Studio 60 still has not evolved into a true three-way design, but remains a 2.5-way system, its lower two 5.5" drivers being rolled off above 500Hz to leave the upper one to carry the midrange up to the 2kHz crossover to the tweeter. Fortunately, the use in the v.5 of the smaller 5.5" drivers should mitigate the slight off-axis brightness that characterizes my Studio v.3s. Second, I was surprised to find that the fixed, solid phase plug of the mid-woofer in the earlier versions has been replaced by a domed dustcap attached to the voice-coil former. This dustcap is now part of the cone/voice-coil assembly, adding to its moving mass. This lightweight bullet may look just like a phase plug, but in my opinion it's more likely to function like a modern version of the "whizzer cones" of ancient full-range drivers.

When I asked Paradigm's Mark Aling about the latter issue, he offered this detailed reply:

Replacing the phase plug with a dustcap has the following benefits:

Increased power handling. With a driver with "regular" excursion capability, a solid aluminum phase plug provides a good heatsink, which benefits long-term power handling. However, with a driver with relatively high excursion (as found in the woofers in the Studio v.5 series), increased power handling was required. Replacing the phase plug with a dustcap creates an "air pump," which forces air under the dustcap to move past the voice-coil at high velocity. This high-velocity air motion over the voice-coil was found to decrease the voice coil's temperature relative to the voice-coil's temperature when a phase plug was employed, thus improving power handling.

Eliminated air-chuffing noises that come from around the voice-coil at high driver excursion when a phase plug is used. At regular cone-excursion levels, the noise created by air passing by the voice-coil and top plate when a phase plug is used is below the threshold of audibility. However, due to the increased excursion capability of the new Studio drivers, the noise due to air rushing over the voice-coil is now audible. This audibility of this noise is completely eliminated by replacing the phase plug with a dustcap.

Increased driver efficiency due to increased radiating area. Because a phase plug does not move with the cone, it does not contribute to the radiating area of a driver, whereas a dustcap (which does move with the cone) does contribute to the radiating area of a driver. By increasing a driver's radiating area, the driver's efficiency is increased.

Join the system
I put the Reference Studio 60 v.5s in precisely the spots long occupied by the v.3s. My Integra DTC-9.8 and Arcam AV888 preamplifier-processors were set to reroute any center-channel info to the new Paradigms, and the pre-pros' v.3-tuned EQs were defeated. This way, when the system was used for multichannel signals, the remaining v.3 in the middle would be ignored and EQ issues would not be a factor. Immediately, I had an Oh-ho! response. The v.5s had a lively, inviting sound that contrasted clearly with the sound of the v.3s, and of the PSB Image T s that had preceded them. More on that below.

Cadillac crossover sends a strong message Milwaukee Journal Sentinel

Cadillac has restyled and repositioned its SRX as a true luxury crossover.

First, the new SRX is a lot edgier and looks like it belongs in the Cadillac fold, complete with a stylish side crease extending up the side through both door handles and tall 1960s reminiscent tail lights.

Engine size shrinks from the giant 4.6-liter Northstar V-8 in its top-line predecessor to the perfectly fine 3.0-liter direct-injected V-6 here. Horsepower drops from 320 to 265 but is still plentiful, just not over-the-top. If you want more power, a 300-horse turbocharged 2.8-liter V-6 is optional.

There was a day when all this downsizing would have signaled a weakling in Cadillac's lineup. Not here. The new SRX is still strong with excellent acceleration and a fun racy engine tone. Tromp the pedal slipping onto the freeway and the SRX responds, hitting 65-70 mph in a fairly smooth burst.

Shifting from the six-speed automatic is not quite as smooth as some other GM combos I've driven.

There's stutter in the uptake as the SRX comes off a corner, and a decidedly heavier feel.

Handling is first rate as the crossover exhibits little lean in turns. It hunkers down real well in tight turns and feels extremely stable.

Ride is firm and comfortable most of the time, thanks to a 110.5-inch wheelbase, but it's a bit too firm over sharp bumps and pavement joints. That firmness no doubt comes from the sport-tuned independent suspension here.

Other performance pluses on the SRX include all-wheel drive with traction control and Stabilitrak stability control. Underneath the SUV features four-wheel anti-lock vented disc brakes too, and the test truck, the AWD Performance model, adds 20-inch wheels. The base model comes with 18-inchers.

Another benefit from the downsizing, the new SRX delivers decent gas mileage for an AWD crossover, the EPA estimating it at 17 mpg city and 23 highway. I got 18 mpg in about 60% city driving and the trip computer was more optimistic at 19.5 mpg. The former V-8 model was rated at 15 mpg city and 20 highway.

Pricing also is improved on this version vs. the former V-8 model, starting at $44,995 compared with about $46,000. The test crossover ended up at $47,115, about $11,000 less than the 2004 V-8 model I tested. The base SRX with front-wheel drive starts at just $33,330.

Inside, the Cady looks sharp, starting with the dash and gauges. The test model had a leather look dash with gray stitching and sophisticated white gauges with a blue circle that almost looks like it's floating on the surface of the speedometer. In the blue circle you get digital trip computer and other data.

The silver test vehicle also featured gray leather seats, wood look trim on the doors, top of the steering wheel, middle of the shifter knob and door on the cubby behind the shifter. Everything here is well laid out with logical controls and good sized buttons and knobs.

Seats are not only attractive but well contoured and powered for easy adjustment. In addition these have three-speed heaters top and bottom and the leather feels extremely soft.

Two other major pluses on the Cady include a pop-up navigation screen and a rear-view camera. That screen also is a radio touch-screen and can be lowered if you're not using it, with the screen then just showing the radio station you've selected, and a digital clock. Other options include power pedals, a Bose 10-speaker stereo, satellite radio, heated outside mirrors, rain-sensing wipers and push-button start.

The test truck featured a giant panoramic sunroof that extended from the front seats to the rear of the back seats.

The rest of the interior is well designed and comfortable, with practical touches like a power liftgate and split fold-flat rear seats.

In back, this one adds the seat-back mounted video screens and DVD system, a $1,295 option.

New-car buyers are downsizing, Ford research shows Examiner.com

NEW YORK, Nov. 18 -- Small is the new big.

That was the word from George Pipas, manager of sales analysis for Ford Motor Co. during a forum on automotive buying trends presented for New York-area journalists.

“What’s taking place,” Pipas told his audience, “ is a compromise between want and need . . . Our view is that small is going to continue to grow and small is going to be more expensive.”

To bolster his point, the speaker pointed out the small-car portion of the market, after remaining stable with an approximate 15 percent market share from 2000 to 2004, has ballooned from 14 percent in 2004 to 21.6 percent in 2009.

The cars he was referring to are known as C segment entries. They include such vehicles as the Honda Civic, Toyota Corolla, Toyota Yaris, Nissan Versa and Nissan Sentra.

Meanwhile, Pipas noted, gas prices rose from $1.49 a gallon in 2000 to $1.85 in 2004, then skyrocketed to $3.25 in 2008, receded to $2.20 this year and are climbing again.

Gas-price volatility is an important factor in the 50-percent growth in small-car sales between 2004 and 2009, he said, but certainly not the only one. Pipas noted that small-car sales have continued to rise since 2008, despite the decline in fuel prices.

In the same time period, he said, there have been major upheavals in the utility-vehicle market. In 2000, the top nine utility vehicles were truck-based SUVs and the l0th place vehicle, the Honda CR-V, was the lone crossover utility vehicle.

Between then and now, the landscape has changed dramatically. The No 1-selling utility vehicle is the CR-V and 9 of the top 10 are crossovers. The lone traditional SIUV, the Jeep Wrangler, is in 7th place. The Explorer has disappeared from the list.

Overall in 2009, small cars represent 21.6 percent of the market; crossover vehicles, 21.2 percent; mid-size cars, 16.2 percent; pickup trucks, 13.1 percent; luxury cars, 7.2 percent; SUVs, 6.4 percent; large cars, 5.3 percent; and minivans, 4 percent.

Pipas said the Millenials, roughly those born between 1979 and 1994, are the hot new demographic. They represent 27 percent of the driving-age population and purchase 11 percent of new vehicles. Forty-nine percent of these first-time buyers are going to the small-car segment.

But, he noted, they want more than base, entry-level vehicles. “They are willing to do without some things so that the things they do acquire have content,” Pipas said.

“If you want to survive, you have to connect with this group,” he warned.

Pipas also emphasized the importance of the Baby Boomers, who represent 32 percent of the driving-age population and 46 percent of new-car buyers. He said research also shows that they are “downsizing, streamlining and simplifying.”

So what is Ford doing to catch the small-car wave?

Pipas said the company will produce up to two million small cars around the world annually by 2012, with up to 10 models sharing the C-segment platform. He also said the company will be selling one million B-Class mid-size vehicles to compete with such entries as the Honda Accord and Toyota Camry.

He noted that the Ford Fiesta, which has already passed the 500,000-mark in sales worldwide, will be unveiled at the Los Angeles Auto Show in December and go on sale in the United States next year.

He also reminded that a new Ford Focus, which will closely resemble the Focus that has been on sale in Europe, will be shown at the North American International Auto Show in Detroit in January, and also go on sale next year in the United States.

Among vehicles sharing the Focus platform will be the upcoming seven-passenger Ford C-Max, a small minivan that is due to go on sale in late 2011 in the United States.
