I have the Bazooka Triangle sub-with about 150 watts going to it. It may not be the most accurate sub in the world, but it certainly puts out a great deal of SPL. I compared it back to back to a Polk/Momo 10 inch, and while the Polk probably needed about 300 watts (as opposed to the 150 I was giving it), There was NO comparison in SPL, impact and punchiness. The Bazooka was simply 5-6 DB stronger across the vast majority of the low end. Ill wait until I get a real head unit and a better Amp before passing complete judgement on its accuracy, but I am completely happy with it. (especially on sale at 99.00 at Circuit City)
