History meets innovation

JBL approached the design of the LSR305 with new ears, but they built the monitors on solid, proven technology. Each speaker matches a 5" long-throw woofer with a 1" damped woven composite Neodymium tweeter to reproduce powerful transients and microdynamics in your mix. JBL's LSR Linear Spatial Reference design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that ‘sounds right' in any working space. The patented Slip Stream™ bass port uses a double-flared shape for greater low-frequency extension and less internal turbulence.

JBL's 5-1/4" 2-way LSR305 powered monitor provides big-time sound in a compact design.

Built to deliver accurate sound — and to last

Separate 41-watt Class D amplifiers drive the woofer and tweeter, so highs, mids and lows are delivered with dynamic accuracy for even the most demanding production styles. Durable balanced XLR and 1/4" TRS connectors ensure that pure, high-quality signal flows from the source to your ears. Just using quality materials and sturdy craftsmanship isn't enough for the engineers at JBL. Before each speaker leaves the factory it must pass a torture test: playing at full output for 100 hours without failure. And each is backed by a five-year warranty. Rest assured: your LSR305 monitors will deliver years of reliable, responsive performance.

A high-tech pedigree

JBL has been building speakers for over 65 years, and they continue to push boundaries in pursuit of great sound. Their Linear Spatial Reference (LSR) design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker that ‘sounds right' in any working space. They also adapted the Image Control Waveguide from JBL's flagship M2 Master Reference Monitor to the compact design of the LSR305. That means you're getting the best mix, and the truest sound possible, no matter where you're sitting.

You're in charge of what you hear

In your studio, you're the boss. The LSR305 allows you to fine-tune the sound to fit your room's acoustics and your personal preferences. Boost or cut frequency response as needed with separate three-position low- and high-frequency trim switches. A -10 dB/+4 dB sensitivity switch ensures compatibility with a broad range of signal sources, allowing you to connect high output professional gear without any danger of input overload.

It's your mix. JBL has gone to great lengths to make sure you hear what you need to hear when you're sitting in the sweet spot.
