Gearank High Notes

Even with the release of the second generation 308P, the original LSR308 is still making waves in the market, thanks to its reputation for sound quality and volume.

It features an 8″ woofer and 1″ tweeter, both of which are housed in a sturdy injection-molded baffle. JBL’s “Image Control Waveguide” is also implemented into the design of this monitor, a feature that spreads the sound more consistently across a wider area, which results in a wider sweetspot. This feature lets you move around your listening area / studio without missing out on important sonic details.

Other features include HF and LF trim controls for tweaking the monitor to match the acoustics of your room.
