I bought this beast, just in case if I cannot get decent SPL out of single 12 inch IB and if I wish to add another 12 inch driver.

I am still hunting for decent 12 inch driver for my IB setup.

For interim, I have added 2X12 inch pioneer drivers (500W RMS each) in a sealed box and they shake the car badly. Sounds awsome but I cannot sacrifice the boot space on long term basis.

Kaigoss, I am considering 12W7 as IB on parcel shelf vs Fi IB3 12 inches. I am looking forward to hear your opinions on this.

Here is specs comparison:

__________________JL 12 W7 --------VS----------Fi IB3 12
Fs:_________________27.2Hz ----------------------23.6Hz
Qts:________________0.482 ------------------------0.57
Vas:________________66L----------------------------83.2L
Xmas:_______________29mm-------------------------30mm
Efficiency (1W/1m)____ 86.2 dB-----------------------83.2 dB
RMS________________750W---------------------------550W


I am more inclined toward 12W7 as I could sell it on easily compared to Fi IB3 if needed. But Fi IB can be coned easily (just in case) compared to JL subs.

Any suggestions welcome.
