Vet...I'm not so sure we should discredit the man. 700 watts RMS could also be anywhere from 1000watt to 2000watt spikes.

I've heard of a 6.5" sub hitting 140's in a crazy ass enclosure...it was a "horned" subwoofer or something rather...Anyways, seeing isn't always believeing and vice versa. Ever heard of that grand national from the 80's? Apparently it was hitting 130's on midbass using horned drivers.
