Should i mod this woofer with PirateLogic MFB?

[StabMe]

Hi!

I have a BNIB car audio subwoofer - Kicker L7S 12" and i was thinking about modding it with PirateLogic's MFB StarBass accelerometer and EVE module.

The driver is a dual voice coil, rated 750W RMS at 2Ohm.

Here are the specs:

Fs - 30Hz
SPLo - 86,9 dB
Qms - 11,2
Qes - 0,63
Qts - 0,59
Vas - 55,7
XMax - 16,25
LE - 4,5mH
Bl - 18,28

Here is how it looks.

Do you think this driver can be a good candidate for modding? Although i can tell good sounding sub bass from mediocre, can spend hours upon hours toying with EQ, DSP, FIRs, routing audio, etc, i am still complete newbie in electronics. Probably, will be asking a lot of questions here in this thread.

I also have a car audio amplifier with ample power which i can power via 220V->12V converter. Do you think that a car audio amp can be used in this application?

I am building a Synergy horn with Beyma bass drivers and Faital HF driver and thought that this sub with an MFB would couple with these speakers nicely.

What you think?

Yes it will work.
It s important that the accelerometer is mounted rigid to the voice coil.
I guess the cone is quite stiff looking at the picture.
Good luck!

Yes, it is indeed very stiff. It doesn't have a dustcup, but i think it is quite easy to drill a round hole in the center of the cone to get the access to the cone, mount the accelerometer, make the leads accessible and then glue the round chunk back onto the cone.

Do i need to make any modifications to the amp in order to make the whole system work?

I would try mounting it off center just close to the corner where two "spokes" are meeting up.
There I guess is a quite stiff small area

Um, i'll be using Piratelogic's stuff and of the available accelerometers, the one that suits me most, i guess, is the StarBass 54, which looks like this:

So it will go inside the coil, glued to the walls of the coil.
