I've seen several small subwoofers in the press recently. These are quite dinky looking, yet are paired with a 1500Watt amplifier. The mags rave about them, but then they rave about anything. I'm considering picking one up and replacing my big ole 150W 12" Paradigm sub. I wonder if anybody here has experiences with these mini-subs and if they really are as good as advertised. And how are those amps rated...that is, is 1500 Watts truly 1500Watts or is a peak number only?
