Extend your system LF all the way down!

JBL Patented Slip Stream Port
This patented JBL port design works in concert with the LSR310S low-frequency driver for deep, dynamic bass response at all playback levels. The double-flared shape of the port is precisely calculated to optimize low-frequency extension.

Wonderful service


Quick delivery great price got a perfectly new looking refurbished unit. Quite happy. Will consider looking to SamAsh for future refurbished products again.



better sound equals better mixes


glad i bought the subwoofer. it really helped with mixing my music and gave me a better sound.



Didn't know I needed it until I started using it.


My recording room is pretty dialed in, but I found I was working on more tracks involving synth-bass lately, so I figured I should get with the times. This unit sounds great and was super easy to integrate.



Great Purchase


Enjoying My Product



I recommend it 100%


I bought this one because I have the jbl 306p, sounds perfect no complains



Absolutely great!


I paired this with the 5" JBL monitors in the same product series. The sub is fairly large, with downfiring speaker and front port. Read the manual, it tells you exactly how to set it up. I actually set both sub and monitors to the same gain after adjusting the switch and use the monitor controller to control input signal. It is true, this pairing does in fact lower your overall output potential. For me, this is a non-issue as I am modeling sound in a highly controlled room. For project studio usage, this combination of monitors is a low cost way to get accurate representation of your mix and master. In pink and grey noise tests in our mix room, we found fairly flat response with no loss in the crossover range. It wasn't "perfect", but definitely usable for almost any practical mixing application. I would not recommend this for home theater use (not because it wouldn't sound good, but there are better options in the price range for that application). I would 100% recommend this for studio use in music, broadcast and folly/sound design applications, even if you have a higher budget. The quality here is consumer grade but frankly, the goal isn't perfect sound but normalizing as closely to sources your audience will typically use to consume your music or sound. This product does that in spades. Subjectively, I think the pairing of this sub with its smaller family makes for a really fantastic sound. Objectively, they are balanced with fair response and won't lead your ears astray. Just be sure to balance monitor and sub output. It's easy to set the sub too high, which happens when you sit too close to it. Remember, bass wavelength is long, so it literally takes some distance for the wave to reach max amplitude. Small rooms can still benefit from a sub provided you treat it to control moral response.
