Pros: Plays great, sounds beautiful. Worth 140 for sure..
Cons: Takes up space, but that is a problem with every subwoofer..
Comments: It has an excellent sound. I would say it works best paired to a Boston Amp, because that's what I have. It uses low wattage (15" is 300 watts Rms) so you don't need a big amp at all, so you'll spend less money on an amp for it. G2 will shake my rear view mirror enough to make cars headlights do circles. You can push it hard or play it easy it don't care, it will sound great either way. It will play 30 hz no prob. Around 20 hz is where its range stops. So it plays low bass well.
