This sub provides solid, clean bass and has an included crossover. It isn't earth-shattering, but for a single 10" sub paired with small studio monitors, it does an excellent job. LSR310S specs are bangs with extremely clean sound. It can satisfy the audiophile and producer. It's hard to find anything wrong with this thing, it does everything it is supposed to and more for a reasonable price.
Very cool technology on JBL's side. They just complete the overall sound and expands the sound stage making the imaging even more spectacular than it was before. The clarity of the subwoofer is simply astounding and the bass is phenomenal. The low end on the thing is fantastic and quite amazing considering this is 10’ woofers. Still, sound clean and accurate higher volumes. You don't feel the need to get any extra bass. For acoustic, classical, and jazz, it's more of stalemate, with the sub being darker, lusher, and smoother and the JBLs being more dynamic (both micro- and macro-) and more 'live' sounding.
Be sure LSR310S setup goes smooth and monitors to the 4 dBu setting while using pro audio equipment such as an audio interface with this sound system. This is the nominal voltage that the speakers are expecting to receive while using pro audio equipment (unless otherwise noted on your interface's JBL LSR310S settings). Things won't be shaking on the desk, but one can definitely appreciate the bass at moderately high volumes. At lower volumes, the sub is noticeable but won't really bother neighbors or even a roommate. If you can afford this sub and already have the 305 monitors, you should definitely buy this.
