"Terrible sound quality"
Pros
The speakers and the sub feel solid, and the build quality is excellent. Gets reasonably loud without distortion.
Cons
The sound quality is not good. Sounds "tinny" or hollow. Perhaps the mids are over-amplified. Although the sub has a level controller, could not get it to sound right - its probably amplifying a wrong frequency. Would not recommend for music.
As pointed
Summary
I wouldn't recommend this as the speakers you pick up if the primary purpose is to listen to music.
