Rated 5 out of 5 by from Good for bandwidth-limited usePicked up a quad of these—three for the dashboard of a 2001 Saab 9-5, and one to use for a center channel at home, as well as to pick up the quantity discount.I made a box out of 13mm (1/2") baltic birch, .22 liters (about .0078 cubic feet) and it seems to work well.I used some buyout binding post plates that were really inexpensive, only had to use three drill bits to do all of the holes. Would have been less if I hadn't put threaded inserts for mounting.Pros:High build quality, large magnet, sturdy case frameExcellent sensitivity, agree with the review that states it seems to be about 3dB more than stated (I had to turn down the relative volume setting about 6dB from the old speaker of similar size)Cons:A bit of a trick to fit it into a 3" hole if you use insulated fast-on connectors (which is a good idea because the motor is so large)You will need to chamfer or round the back of the hole in material above 1/2" or so, so it can breathe, again because of the motor sizeHighs could be a bit more extendedCould be a little cheaper.

Rated 5 out of 5 by from Excellent imagingI have built 2 sets of speakers with these speakers (used as a midrange). 300hz to 3500HZ with a custom crossover and 800hz to 5000hz on another set with the dayton $10 crossover (worked great). I was not planning to use a midrange in either project, but until I added these, the speakers did not image well. In both cases, it made the tang band mids add a bright and "live" sound, It's like the singer is right in front of you. These speakers made a huge difference. They are bright so an L-pad is a good idea so you can blend them into your system. I've already got a set ready to go for my next system.

Rated 5 out of 5 by from Give it plenty of break-in timeNote: these speakers seem to be more sensitive than the manufacturer indicated, by about 3dB. They were overpowering in my 3-way cabinets, but after fixing it with an L-pad, they performed quite well. Break-in time is kind of long. They have been playing loud for a few days straight, and the sound is still softening up. They will be much better after a week or so.They resonate at 10kHz, several dB peak. To alleviate that, i just crossed them over for strictly midrange frequencies, and used a woofer and tweeter to cover the rest. Highly recommended. Get x-over pro 3 or something like that so you can do your own crossovers

Rated 4 out of 5 by from decently impressivei was expecting these puppies to blow me away, my expectations weren't met. but, dont get me wrong they are very good. i have these as computer speakers, full rage units and are very good sounding. decent bass from a very small speaker. not a bad deal for $13. oh forgot to tell you, i hooked 'em up to my reciever and played them alone in a very large living room, then i was really impressed!

Tang Band W3-315E 3" Aluminum/Magnesium Full Range Driver

I notice on the frequency response graph, that this has an almost 10dB rise at 10k. I was wondering if a 2mF capacitor to act like a 6 dB filter would help control this.  In my reading people have cautioned against this "cone break up" being harsh. Thanks

Asked by: Cowboyinthejungle
A capacitor will act as a high pass filter, not a low pass. In order to bring that frequency down you would need a notch filter, but we have no way of modelling one. Chances are that bump above 10kHz won't be too bad, there isn't much information that high and its above the sensitive portion of our hearing. I have heard this driver and it sounded perfectly fine, and I generally do not like metal cone drivers.

I have a set of TechTalk speakers I made years ago that use the W3 315D. One of the woofers was damaged when the speaker fell. Is the W3 315E a direct replacement? The specs seem the same.

Asked by: SpenceW
I am not sure what the difference is between the D and E models, however as long as the cone materials are the same and they share the same impedance, they will likely be a fine replacement. Chances are the only difference was magnet shielding or something like that.

Speakers for home theater

Hi,I want to assemble a set of 5 speakers for home cinema, I liked these drivers because they are small. My amp is class D with the following features: 5x100Watts power, frequency response 180 Hz to 18KHz / + - 3db.Will it work well? or advise me other drivers?Regards
Asked by: quiquas
If you want bass, you won't get it from am amp that starts at 180 Hz. Nextly, these drivers sound bad without a tweeter and xover network due to the intense cone-ringing they exhibit. Recommended xover is second or third order at 2.5-2.8kHz, with a notch on the resonance. They are really nice when they are used properly.
