Big Boom for the buck...

I have eight of these subs and they rock. Weight verses having an amp rack or two full of amps is not that bad at all. These were some of the first ones QSC shipped three years ago and they have had NO problems what so ever!

I bought a pair of 181i's after being blown away by the 122i tops. Let me tell you that I have heard a lot of gear, but no subs comes close to these. 700 continuous Class H watts....pure! If you're looking for subs, BUY THESE! A little heavy, but equipped with 3" casters, so not bad to transport at all. The weight is the only con...everything else-all PRO.
