Anyone heard this sub at all? I know it's got one of Sony's new S-Master Pro digital amps driving it for 1000 watts, and I believe it has two 12-inch woofers...I think it might be ported? Not sure though. And I know it retails for £500, but can be got for £350 at various places. Anyone know anything else about it? Most of the reports from the States seem to indicate this new digital amplification from Sony benefits bass the most, so I am interested in this sub.
