JBL LSR310S 10" Powered Studio Subwoofer with XLF

Extend your system LF all the way down! The LSR310S Powered Studio Subwoofer incorporates JBL’s patented Slip Stream Port working in concert with a custom 10" down-firing driver and a 200W amplifier to add deep, powerful bass to any studio monitor system. The unit’s XLF Extended Low Frequency setting lets you hear your tracks with the augmented bass tuning used in today’s dance clubs.

JBL Patented Slip Stream Port

This patented JBL port design works in concert with the woofer’s 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.

XLF Extended Low Frequency Setting

A JBL first, the XLF setting activates a specially-engineered tuning that emulates the ample bass tuning used in today's dance clubs. When producing a dance track, the XLF setting will inspire you and bring a bit of the club to your control from. For inspiration to the max, position the LSR310S Subwoofer in the nearest corner of your room and activate the XLF setting.

Custom 10" Down-Firing High Excursion Low Frequency Driver

JBL Transducers are legendary for their performance. The custom-designed driver in the LSR310S Subwoofer exemplifies JBL engineering prowess, delivering deep low frequency response into the 20 Hz region, and 113 dB peak output, for long periods at full rated power with no risk of failure.

Professional Balanced Inputs and Outputs

Thanks to the balanced XLR and 1/4" inputs and XLR outputs, you can add the powered subwoofer to any studio monitor system to extend its low frequency performance or use it as the "0.1" LFE Channel in a surround sound system.

Selectable Input Sensitivity

The -10dBV/+4 dBu sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect the unit to high-output professional equipment without any danger of input overload.

Three Crossover Settings

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.

Volume Control

Simple and effective, the subwoofer’s volume control has detents that make it easy to balance it in your studio monitor system.

JBL LSR310S 10" Powered Studio Subwoofer with XLF

JBL LSR310S 10" Powered Studio Subwoofer with XLF SKU: LSR310S

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.
