JBL LSR310S 10” Powered Studio Subwoofer

The Foto Crown Provides JBL LSR310S provides the clarity and power that modern studios demand. Designed to integrate seamlessly with JBL’s 3 Series monitors, this 200W Class-D powered subwoofer brings depth and impact to music production, mixing, post-production, and even 5.1 surround sound setups. Whether you’re crafting a cinematic score or finalizing a bass-heavy track, the LSR310S ensures that the low frequencies are represented with precision.

Deep Bass with Intelligent Port Design

At the heart of the LSR310S lies a 10-inch low-frequency transducer paired with JBL’s innovative Slip Stream Port. Engineered to deliver a smoother air flow and minimize turbulence, this port design enhances low-frequency extension and clarity. Because of this, the subwoofer is capable of producing a peak SPL of 113 dB, allowing it to deliver impressive volume while maintaining sonic accuracy. This is particularly helpful when monitoring the sub-bass content of modern music genres.

Extended Low Frequency Mode for Club-Style Mixing

To meet the needs of electronic music producers and DJs, JBL has included a Selectable Extended Low Frequency (XLF) mode. Inspired by the bass response characteristics found in modern dance clubs, this setting allows users to emulate the sub-heavy sound of club systems. As a result, the LSR310S offers a more accurate reference for how tracks will translate in live venue settings, enabling producers to make informed creative choices.

Versatile Crossover and Input Settings

To adapt to different studio configurations, the LSR310S includes flexible integration options. A 3-position crossover control allows you to choose between 80 Hz, XLF (120 Hz), or external mode, which supports the use of an independent crossover system. Additionally, the selectable input sensitivity switch helps match the subwoofer to a wide variety of audio interfaces, monitors, and control surfaces. Because of these options, setting up the LSR310S within an existing monitoring chain is both quick and reliable.

Built for Modern Production Workflows

Although compact in form, the LSR310S is engineered for the demands of today’s high-pressure production environments. Its rugged enclosure houses high-performance components that can handle continuous monitoring at elevated levels. The extended low-end response also makes it easier to identify and correct problematic frequencies during mixdowns, particularly in genres where bass plays a central role.
