JBL LSR 310 S

This sub-woofer is perfect for freeing the monitors from the arduous task of reproducing very low frequencies. Used with care and in a correct "dosage" in correspondence with the room and the monitor system you have will produce much better results than before.
On the downside, it is a little bigger than I imagined and looks more like a night stand. However because of this, I now have a place to put my audio interface.

I wasn't expecting much from the price. I own way more expensive subwoofers and monitors.
I bought this one for my holidays house, and immediately I fell in love with it. I use it to extend the bass range of my genelec m040 and I can say that it doesn't look bad at all compared to them

Totally recommend this subwoofer especially if you are using the JBL LSR 305s and JBL LSR 308s all together. Low base response at 20hz range. Very happy with my purchase. Money well spent.

LSR310S is the perfect companion for LSR305P because it gives that extra low end, often needed, to reconstruct better a sound or a group of sounds.
Especially in the home/project studio, like my situation, this subwoofer makes the difference. Used mainly to rehearse during the composing phase, it helps listening to a more satisfying sound because it increases the overall definition.

Bought this to compliment JBL LSR305's (which are excellent) It adds some really nice sub-bass and thump to the overall sound. Need to be careful with the level-I had to keep the volume down pretty low to avoid overwhelming the mix in bass (sounds nice but you end up with bass-lite mixes) The lower price made it an irresistible purchase. Would have been nice to have an easy option to toggle between subwoofer in and out-only criticism really

Perfect audio advancement for JBL lsr 305 - this setup can do much :) There is enough low frequency (even to much and i had to decrease it to 3/4 to match lsr 305) Home music experience became complete now ;)

Clean sound, quality made, good design

One of the best subs I heard, and I owned 15 times as expensive subs

Sounds great with my dynaudio bm5a
