The SA-15M.3 dual-angle floor monitors deliver professional stage monitoring for bands, DJs, and live sound engineers who need reliable vocal and instrument monitoring. This pair of wedge-style monitors handles everything from intimate acoustic sets to full band performances.

Each 15-inch monitor delivers 250 watts RMS with clean vocal reproduction and solid low-end response. The dual-angle design lets you position each monitor on either side for the perfect monitoring angle, whether you're dealing with cramped stages or need precise aim for different performers.

The 2-way design pairs a 15-inch woofer with 50-ounce magnet and 2.5-inch voice coil with a 4x10 piezo horn tweeter, covering 45Hz to 20kHz at 8-ohm impedance. At 96dB sensitivity, these monitors cut through stage volume without excessive amp power. Dual ports enhance low-frequency response for fuller vocal monitoring.

Use these monitors for band rehearsals, church worship teams, DJ monitoring, or small to mid-sized venue performances handling up to 200 people. The wedge profile works equally well as floor monitors or elevated mains using the included pole mount. Each monitor features dual 1/4-inch inputs for daisy-chaining or running separate mixes.

Connect directly to your mixer's monitor sends or amplifier outputs using standard 1/4-inch speaker cables. The rugged plywood construction with steel grille and metal corners handles regular transport and stage use.

Seismic Audio backs each monitor with a one-year warranty and ships factory-direct for professional sound at a practical price point.

Frequently Asked Questions

What size venues work best with these monitors?

These 250-watt monitors handle venues up to 200 people effectively, whether used as stage monitors or elevated mains. For larger outdoor events or venues over 300 people, you'll want to add a subwoofer or step up to higher-powered mains. They're perfectly sized for church worship teams, wedding receptions, small club gigs, and rehearsal spaces.

What cables do I need to connect these monitors?

You'll need standard 1/4-inch speaker cables to connect from your amplifier or powered mixer to each monitor. The dual inputs on each monitor let you daisy-chain multiple monitors or run separate mixes to each input. Make sure to use speaker cables, not instrument cables, for proper power handling and signal transfer.

Can I use these as main speakers instead of just monitors?

Yes, the included pole mount lets you elevate these as main PA speakers for smaller events. The dual-angle wedge design works well on stands, though the 15-inch driver and 250-watt power handling makes them better suited for intimate venues rather than large outdoor events. For bigger crowds, consider pairing with a subwoofer.

How do the dual angles work on these wedge monitors?

Each monitor can be positioned on either its left or right side to change the monitoring angle, letting you aim the sound precisely where performers need it. This dual-angle feature helps maximize stage real estate and ensures every band member gets proper monitoring coverage, even on crowded or oddly-shaped stages.

Do I need an amplifier to power these monitors?

Yes, these are passive monitors requiring an external amplifier or powered mixer. Match them with an amp that delivers 250-500 watts per channel at 8 ohms for optimal performance. Many powered mixers in the 400-600 watt range work well, or you can use a dedicated monitor amplifier for multiple monitor mixes.
