HiFi Class (Poland) gives SB-1000 Five Stars

“Massive, springy and strong bass from a small compact box. Effective and precise sound in a multi-channel configuration. It will also well complement the sound in the lowest tones of the classic stereo systems. Difficult to upset even when I forced it to work at higher than average volume levels - the bass was always played with proper control, without compression or audible distortions. Boasts performance I would expect from much more expensive constructions.”
