Good idea? Bad Idea? Guitar & Bass 4x12

[Fender_Punk]

So here the idea I've got:

Take a slant 4x12 with guitar speakers in it and remove the bottom two speakers. Replace with two 12" 200W car subwoofers and wire them to a separate jack, which is in no way connected to the jack with the guitar speakers.

Send a cable from the 1x12 guitar combo amp to the jack wired with the two guitar speakers and a cable from the 1x12 bass combo amp to the jack wired with the subwoofers.

So effectively, each amp is running with one 12" in it's own combo plus two more in a shared 4x12. Good idea? Bad idea? Insane idea? WHY?

I like the way you think. I think it would equally up the volume of the guitar and bass, and maybe help meld the two together tonally. I feel it's worth trying, I'm just wondering what all the tone snobs, I mean aficionados think!

Electrically it will work, but be sure to pay attention to the total impedance. The math could get weird depending on how you wire it all up.

Also, car subs tend to have a very low top end. A bass guitar can generate some fairly high harmonics. (Which is why so many bass amps use "10" speakers.) The car subs will probably be fairly dark and muddy.

Hmmm. Good point

The mounting of the cone is not tight enough to get the response you need.

It is a "sub" woofer. To produce the frequencies, the cone has to move great distances.
They (10" or 12" car subwoofers) have a frequency response of ~20 to 500 Hz
Compared to a 15" bass speaker (Eminence for instance) which goes to 3.7kHz.

Sensitivity ratings are very far apart as well. 91dB for an Infinity Kappa 12" (car subwoofer) vs 99.2 Eminence Delta Lite 15"(bassguitar speaker).
(To increase the volume by 3dB you need to double the power etc.)

Infinity make nice speakers. Cheaper brands don't even get that sensitivity rating (Kicker - Comp 12" 88.3 dB)


Not saying it can't be done... Question is, is it going to deliver what you are looking for?

I have to agree on the top end response from the car speakers, but I would also think that the pressure inside the cab created by a guitar signal and a bass signal could possibly affect something.

I had a Rockford-Fosgate PUNCH car subwoofer in my 1x12" bass amp once - it was actually pretty fukking cool.

WOOMP WOOMP WOOMP

With mixing guitar and bass speakers in one cab, you're looking at a little phase cancellation and stuff like that, but that is not A) guaranteed or B) constant
