Summary: There are other reviews that talk about sound quality but not much about audioengine's customer support. Sadly, my s8 broke after 6 months of almost daily use. I emailed audioengine and they would always reply with in 24 hours.
Beautiful rich sound. Control knobs and setup guide could be better.

Summary: First, I don't need to add anything to what other reviewers have said about the great sound quality across the music spectrum, I'll simply agree with them. I do think the 3 control knobs on the back could be improved.
Summary: I'm using this subwoofer along with audio engine A5+ speakers and I'm very satisfied with the sound quality. On the lowest setting it still cranks out plenty of bass. If you really wanted to drive your neighbors crazy this would surely do it!
