Decent for its price.. don't expect it to go below 50hz, even though it is advertised as 20hz. Unfortunately, after a week of use, while playing at low volumes (never went above half), and after being calibrated with audyssey from a Denon amplifier, suddenly a loud crackling noise started and the bass completely disappeared. I'm waiting to send it back to the company for inspection.

Very good.. quite powerful for a 50sqm living room.
In terms of sound, something more expensive will definitely perform even better, but it is by no means bad.
Worth the money! Now, I just have to see how it will hold up over time.
