The JBL LSR310S is a powered 10-inch studio subwoofer designed to extend the low-frequency performance of any monitoring setup with deep, accurate bass. Featuring JBL’s patented Slip Stream port technology, the JBL LSR310S delivers tight, dynamic low-end response with exceptional clarity, even at high playback levels.
Its custom-designed 10-inch down-firing driver produces low frequencies that reach into the 20 Hz region, achieving powerful and precise sub-bass reproduction ideal for music production, post-production, and sound design. Powered by a 200-watt amplifier, it provides high output and long-term reliability. The unique XLF (Extended Low Frequency) mode emulates the boosted bass characteristic of modern dance club systems, giving producers an inspiring reference when mixing low-end heavy genres.
With balanced XLR and ¼-inch inputs and outputs, selectable input sensitivity, and three crossover settings including 80 Hz and External, the JBL LSR310S integrates seamlessly with JBL 3 Series monitors or any professional studio setup. Its robust build and simple volume control ensure consistent, balanced performance in every application.
