A class above any other sub out there

By LA Funk Master

from Lafayette, LA

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.
