JBL LSR308 Powered Studio Monitors

The JBL 3 Series powered studio monitors are designed to deliver pro performance at an affordable price. The LSR308 is the larger of two monitors in the series, employing a magnetically shielded 8-inch woofer and a 1-inch soft-dome HF driver in a ported cabinet. A 56-watt, Class D amplifier powers each driver, enabling the LSR308 to achieve maximum SPLs exceeding 110dB.

Molded into the LSR308’s front panel is JBL’s patented Image Control Waveguide. Initially developed for JBL’s M2 Master Reference Monitor, the Image Control Waveguide was engineered to ensure a broad sweet spot, wide stereo image, and resolution of subtle details—all of which I found to be true. An LED power indicator is recessed into this panel, set between the vertically aligned tweeter and woofer.

By providing pro-level playback at a personal-studio price, JBL has clearly achieved its goals with the LSR308. It’s an excellent system that makes mixing easier. If you’re looking for a new set of monitors, the LSR308 deserves serious consideration
