JBL LSR310S Active 10" Powered Studio Subwoofer with XLF

Product Information

I use mine via a direct connection from my monitor controller and do not use the built in crossover. Once you get it dialed in (which you likely won't - these don't balance correctly because the output is super low unless you crank it - the problem is - when you crank it, you have to turn down your mid/high monitors, and the input levels won't match. Basically, you will lose out on a bunch of sonic detail. When dialing your sub in, remember that "less is more." I've found this to be true in just about every facet of life. The 80 Hz setting is recommended for use with the LSR305, LSR308 or any studio monitors. The External setting allows use of an outboard crossover.

I do not have the output running through the sub and up to the mains as most do. Instead, I control the mains and sub separately from the MC3. When I first hooked it up, I tried a pair of balanced cables and wondered, "where did all the bass go?" Figuring I might have a polarity issue, I tried one channel only — same thing (what the???).

There's a lot of great information to be found in this article.It took me a few minutes to dial in the JBL, but once I figured that out it sounds smooth and complimented my setup perfectly. I'm not sure why anyone in a studio setting would want to use anything but the 80hz crossover. It had PLENTY of power, in fact, it's set to about 40 percent power to balance out with my studio monitors. Folks that say it doesn't have enough power need to turn down the gain of their monitors. Very clean meshing with the JBL LS305's I'm using for monitors. Very easy to hook up, no adjustment was required. Just make sure it's all setup like the manual tells you, and you're golden. The whole idea of a studio sub is not to blow you away (which this can certainly do) but rather to compliment (extend the frequency range of) the monitors. It does this very well. If you don't use this balance, your mixes will not be accurate may result in them being low-frequency deprived. This sub completely changes music; I'm using it with two JBL 3 Series MkII 305P speakers supported on stands; the 305Ps connected to this sub and then the sub is connected to a "SSL 2" interface; the interface's usb cable connected to my CPU.

Connections

A TRS connection into one side only yielded the weakest output—same with XLR. Going to an unbalanced mono guitar cable into one side gave me much better output but I suspected there was better. Finally, I used an unbalanced guitar cable in one channel only. Boom! There it was! My studio is in the middle of electrical interference hell (aka the Silicon Valley) so I used a balanced cable from the MC3 to the JBL but terminated it with a 1/4TRS-F to TS-M stereo to mono converter (Hosa GPP-290). Now I had a balanced line with a mono plug. Hey, it works and is quiet.

Hugely powerful. Would probably take the paint off my walls if I cranked it too much. However, even with the imposing power, it's never boomy or distorted. Create the full-range sound you need out of your studio monitors with the JBL LSR310S active subwoofer. The rich and full low end you'll get from the 200-watt Class D power amp and 10" woofer will make it easier than ever to create amazing sounding mixes. When you activate the XLF Extended Low Frequency Setting, you'll get a club-like response that will help you tailor your bass volumes and frequencies to perfection. The JBL LSR310S powered subwoofer delivers deep bass down to 27Hz to round out the sound of your studio. Ported design means more accuracy at low volume levels Overall this is a great buy and I'm super happy with it. I'll probably never actually get rid of it.To sum up, I finally got the promised output and it balanced nicely with my monitors. I also found some shelves that now rattle because of the extra bass (easily fixed). The downward-facing driver ("Low Frequency Transducer") has a diameter of 10 inches, which corresponds to about 250 millimeters, and has a very soft surround and a fairly large, maximum deflection of almost two centimeters (3/4-inch). By the way, "transducer" means structure-borne sound generator and is a clear indication that the loudspeaker radiating downwards should reproduce the low frequency components that are particularly popular in surround environments and that are barely audible but physically perceptible.
