Super happy with the M10-V2, never had a real sub, it was replacing some cheap 8" which is paired with Kef Q150, so far pretty good. It took sometime for me to realize the deep bass, I was mistakenly expecting loudness that was my bad.

Its really Massive and heavy though, had to put next to the couch trying to blend them as corner coffee table, since its so big

Powerful, linear and punchy. Great price and very fast delivery from Monoprice.

cant say enough had it on low volume playing a heavy bass song and next thing i know is im getting a knock said his walls were vibrating and he was across the hall
