I purchased this subwoofer to complete a 2.1 system for my PC with some JBL LSR305 speakers. The normal bass setting is subtle and good overall. I enjoy the XLR bass setting more though as it gives it that extra hit down low.

Ordered this for use with the surprisingly good JBL LSR305 speakers. Had moved the 305's to a bigger room. This filled out the low end nicely. Gave the speakers a calmer and authoritative sound like much larger speakers. This being an easy setup since you were provided with cables needed.
