Alto SXM112A

The Alto SXM112A is a purpose built 12″ foldback stage wedge designed to deliver clear and accurate monitoring on stage. Easy to set up and use with its internal 800W Class-D amplifier and onboard DSP which allows you to change the charateristics of the speaker with the turn of a knob. The SXM112A delivers a big sound with a high-performance 12-inch LF driver (2-inch voice coil), and an exacting 1-inch HF driver. What’s more, it utilizes a trapezoidal design which greatly decreases the resonance of the standing wave in the cabinet for a more true and exact sound reproduction. The SXM112A is the perfect solution for club installations, rehearsal spaces, gigging musicians, mobile DJs, and houses of worships who need additional sound reinforcement.

Road Ready
Built to take a beating night after night, week after week, the SXM112A’s cabinet is made of thick birch plywood, features a heavy-duty steel grill that’s built to last, and is covered in a rugged black textured finish that is scratch and dent resistant. Recessed handles make the SXM112A easy and safe to move from rehearsal space to stage and back again while heavy-duty rubber feet ensure that it stays put no matter how much volume you pump through it.

Plug It In, Turn It On
The SXM112A houses more than just great sound under the hood, it features a built-in Class D, 400W bi-amplified system (800W Peak). As a self-powered stage monitor, all you need to do is plug in your audio and power cables, turn it on, and you’re all set. No external amplifiers to set up or transport — it’s all built into the SXM112A.
