JBL has been in the sound reinforcement business for over 7 decades now. So it is not surprising to find that the LSR310S has been on our recommended list, a powered subwoofer with a 200W amplifier and a down-firing 10" speaker, tailored for studio monitoring use.

It features a ported cabinet design that improves bass response at low playback levels, and reduces turbulence to ensure clarity.

Other features include selectable crossover settings and level control.

Pros

One user put it nicely, the JBL LSR310S is physically and sonically imposing, and most of the reviews agree that it sounds much bigger than expected. Many describe it as having clean and tight sounding lows, and that it integrates well with the JBL LSR308, which resulted in a fuller sound that helped many with their mixing and production duties.

Cons

Lack of overall volume came up a few times prompting other users to provide tips on how to better position or setup the unit for improved results.

Overall

If you're looking for a quality subwoofer from a reliable brand that matches well with JBL speakes or any hi-fi sound signature monitoring setup, then check out the JBL LSR310S.
