Im currently wanting to try something new and I was wanting to know what would be a better choice.. I have 2 5000rms amps for each 12" woofer I intend on using. So Im wanting to a setup with 2 12's and its between the AA Mayhem or the Fi BTL 12".. I dont have any dealers of AA in my area and it don't seem like they do much of the speaker customizing like Fi does... So whats everyones input?

BTL 12" vs. Mayhem 12"?

So you're looking to send each 12'' 5000 watts?

Well I figured after volt drop, imp rise and all the other factors roughly 4k~4.5kw.. So yea kinda sorta.. haha

You could wait for those new SMD woofers >

Yeah.. I was thinkin about those as well.. But Steve said the 12" models would be a little while longer than the 15" and 18".. I want to only do 12's

Do you have a budget or space constraints? I think (4) 10's with 1000+ would be awesome. Or maybe (3) 12's but then the final load would be weird.

Yeah, I do remember reading that now that you mentioned it.

EDIT: I would go with the Mayhem's. Seems everyone has BTL's.

I dont have BTLs

Me either.

I do

They are basically the same thing.

They are basically the same thing.

Wrong!

has anyone used both yet?

would you please stand on the difference between them ?

totally different motors would be a good place to start?

I have used both -

BTL = motor is single larger diameter slug

Mayhem = triple stacked motor

(4) BTL's were 0.7 dB louder vs. mayhems with the same box, same amps, but I did not measure actual power to see if the amps were making more power with the BTL's (Maybe slightly different impedance in the box).

Mayhems seem to sound a little smoother. . .

I would have to say BTLs but I have not heard or used the others before..
