Designed for powerful performance

JBL's STX812M passive monitor loudspeaker packs a 12" driver in a 2-way design for maximum sonic quality. High frequencies sound clear and natural too, thanks to JBL's 3" neodymium magnet compression driver. And because the STX812M handles 1200 watts RMS, you'll be able to put out a lot of sound. But they're not just great at getting loud - the high power rating gives the STX812M the needed headroom to reproduce your sound with exceptional clarity and presence and no distortion.

Road-ready construction

If you need high-quality portable monitor loudspeakers that can take abuse, you'll appreciate the STX812M's design. You get multi-ply birch/poplar construction, coated with DuraFlex for maximum protection. The hardwood cabinet isn't just strong, it reduces resonance for cleaner sound quality. And with a rugged 14-gauge steel grill protecting the drivers, you can be sure your STX812M is ready for virtually anything.

Bad to the bone

Bought a pair for monitor use. I must say they sound great with a full and sound solid. Some speakers sound loud with piercing highs and a mid speaker that's muffled. This speaker has an all around solid sound with highs and mids that compliment each other. I'm pushing them with a crown ma5000i amp. I'm very happy with my purchase.
