I bought these as a supplement to my main system for large rooms and outdoors. Compared to my Bose 302's and pair of Bose MB4 bass cabs, these don't quite have the same frequency response but that's not why I bought them. Bose fill a room nicely but these just throw sound confidently! They are big. If I had a sense of scale, I might have purchased the 12 inch version. My only gripe with these is that the knobs protrude well beyond the back plane of the speaker and I fear they will get damaged in transport. No gig bags provided to protect them. Overall, for the price, you won't regret it.
