Thank for the review
zieglj01. Soooo Outlaw M8 or BIC F-12???

Which would produce better natural bass?
The word on the Bic is that it is more boom than musical - more for
the Home Theater crowd - the M8 attracks me more. The Bic should
play louder - However, I would be surprised if it went much deeper.
I do not believe that Outlaw would put their name on a sloppy product.
This is a little test of the Bic sub, from a review on Amazon
This review is from: BIC America F12 12-Inch 475-Watt Front Firing Powered Subwoofer (Electronics)
I actually have a pair of 10" SVS subs, and then purchased this 12" sub for a friend. I did some testing with not only music but since wave test tones. Running 1/3 octave sine wave test tones through both brands, this 12" sub is very peaky at around 60hz, and output starts to fall rather steeply beyond 40hz-35hz... It does produce 25hz sine wave tones, but at very low levels that is basically not audible relative to the higher frequencies this sub can make. And at about 20hz, you can obviously hear doubling effects from this sub, where there is quite a lot of 2nd harmonics at 40hz present... So, this sub is not very loud at low end bass below 30 hz, has a rather poor bass response linearity (very peaky), and produces too much of 2nd order harmonics at its low end response (will make some music such as pipe organs sound like one note bass). It is great for making explosion sounds or pop music that is heavily equalized from 50hz to 80hz, but very poor at producing loud and clean low frequency notes of a large pipe organ below 35hz...
