C12.1 Alum cone 12" available, similar to old AV12

Postby stryke » Thu Nov 01, 2007 4:49 pm

Hi Everyone,

We have some more closeouts available, This is the C12.1. These are also quite similar to the older AV15's we used to sell. They use the same 2" coil, cone, etc. They are dual 2ohm coil. These have the addition of copper sleeve covering the entire pole to lower inductance, like the Lambda woofers. As a result Bl is slightly lower as the pole OD is turned down .050" to fit the copper on.. They are a very nice low distortion 12" driver with 23mm Xmax for $125 each.

Here are the parameters and a picture:

C12.1 12" alum cone woofer

Quantity Available: 6pcs

Fs: 27Hz
Qts: .5
Qms: 9
Qes: .48
Re: 3ohm
Bl: 16Tm
Z: 4ohm
Le: 2.3mH
Vas: 37L
Mms: 265g
Cms: .13mm/N
Sd: 446sqcm
Xmax: 23mm
Vd: 2.06L


These will be ideal for a small sealed enclosure for car audio. Around 1 cubic foot sealed would be perfect with box fill.

Give us a call 920-469-9198 to place an order. At $125 each these will not last long.

Yeah, these are close to what our SL12's will be in the near future. They will retail at $149 and SL15's at $179.

i like the black on the basket, and the way the leads are on the spider.

Well, If these are a hint of what you have comin for us in the future. I can't wait till you get every thing up and running. I've been hunting for a sub that meets my requirements for over a year now. found lots out there that came "close" but just didn't cut it in one form or another.
Any chances you'll be coming out with a 10" version, or at least any 10" drivers? I'd gladly go dual 15"s, but dual 10"s are a lot easier to pass by the wife ;)

Will the SL12 use the same 2'' coil or will it have something bigger say a 2.5'' coil?

The SL12 will have a 2" 4 layer flatwire copper coil. The AV series will be our top line for now stepping up to the 2.5" coil. We have had continuous power handling of up to 1000W on our 2" coil with copper sleeve on the pole, and 1500W on the 2.5" coil.

People don't realize just how important a copper shorting ring really is not just for distortion and inductance, but for wicking heat from the VC. It is Highly electrically conductive and thermally conductive. Many people think that the steel pole piece will absorb heat quite well, and it does, just not very quickly. The biggest factor in cooling a VC and keeping it cool is to pull the heat from the coil quickly. This keeps power compression very low. Otherwise as you deal with power compression you have to put more power into the VC to keep the same output level. This is why most SPL competitors find their first run to be the loudest. As the VC heats, resistance rises and you are no longer delivering as much power to the coil.

So, people ask why we don't do larger diameter coils. For our own products we never needed them. We can already handle plenty of power, our motor strength is right where we need it, and the smaller the diameter coil means lower inductance and distortion.

WOW great answer i believe the same and thats why i find your subs fascinating. Speaking of motor strength what will the AV have (in BL), by the sound of things you guys have a magnetizer which would be great. I think it would be awesome to have a 36k or 42k joule magnetizer.

I'm honestly not sure what our magnetizer is rated at. We bought it from our magnet supplier. They used to magnetize boxes of magnets at a time with it. So far we haven't found anything we can't magnetize in it.

I never got his magnetizer. There were some issues with getting all of his stuff from him. The other thing was that it was only large enough for his one size motor. The larger stuff we do we couldn't have magnetized with his anyway.

We currently stock 3 sizes. The smallest is 5 1/4" x 1" thick, middle is 6 1/8" x 1" thick and largest is 7.5" x 1" thick. We will soon be stocking an 8.5" diameter x 1" thick also.
