Very true. I guess I can bear with single 12 inch till you or somebody else can fit IB behind the rear seats. In that case, I could go max for 15 inches sub in the boot.

I was reading the reviews on SBP15 last night. Brilliant driver.
However comparing it to Fi IB12, its xmas is limited and on 20Hz 250W RMS is enough to take it to its Xmas (though it is 7dB louder than Fi IB12) and that is coming straight out of John's posting.

Whereas Fi IB3 takes 500W RMS @ 20HZ to reach its Xmas. In a way it favours SBP15 as it takes less power to create more sound but then with Fi IB3, there are less chances of mechanical failure due to greater Xmas (unless I am missing a point here).

So considering that, I am getting confused which one would work out better in IB setup?
