JBL LSR310S is rated 3.7 out of 5 by 3.
Rated 5 out of 5 by from Nice control for different styles I work with a variety of clients who have vastly different Audio needs. I paired this sub with some LSR’s and have been very pleased. Whether it’s a singer/songwriter with an acoustic guitar and vocals or EDM/club music, this setup is very adaptable. Just give your speakers some space away from hard reflective surfaces and enjoy! One note - I wish there was a protective grille; it would just give me some piece of mind.

Rated 5 out of 5 by from Tight and responsive bass I ordered this a few weeks after I received my 3 series monitors. I found the 3 series excellent and didn't want to disrupt the sound of them but I did find the low end while good wasn't what I wanted in my system. After some long consideration of this device I made the buy. I couldn't be happier with the subwoofer. Its tight and responsive and doesn't muddle the image that the 3 series monitors cast so well. I did find that I needed to adjust the levels of the sub down quite a bit to avoid over doing it in my room. However that is not a flaw in the device but rather just a message on the size and power of this device. It does a great job at roughly half the power output setting on the knob than I have on my monitors. Overall very powerful and really like it. Definitely worth the investment to fill the room with extreme low end.

Rated 1 out of 5 by from Defective out of the box. Was really excited to get this for my JBL305’s. Set it up and got a constant hum. Unplug everything except power and still humming. Call for support and I get we can’t help you with JBL “professional” products you need to call the “professional” support team that is not open. So I returned it, at least that was easy.
