The SA-15M pair delivers professional floor monitor performance for bands, solo performers, and small venues that need clear vocal and instrument monitoring on stage. These passive 15" wedge monitors require an external amplifier but offer the flexibility to match your existing power setup.

Each monitor handles 250 watts RMS with a 15" woofer and piezo tweeter delivering full-range sound from 40Hz to 20kHz. The 8-ohm impedance and 97dB sensitivity work efficiently with most amplifiers, while the 2-way crossover ensures vocals cut through the mix without muddy low-end interference.

The 5/8" plywood front panel construction with black carpet finish and metal corners handles regular transport and setup. Dual 1/4" inputs on each monitor simplify daisy-chaining from your amplifier, while recessed handles and the compact 23" x 18" x 17" footprint make load-in straightforward. At 38 pounds each, these monitors stay put on stage without being unwieldy to move.

Whether you're running vocal monitors for a 4-piece band, providing drum monitor feeds, or setting up floor monitors for a small church or wedding venue, this pair covers stages accommodating 50-150 people. The wedge angle projects sound directly to performers without excessive stage volume.

Connect via standard 1/4" speaker cables from your amplifier's monitor outputs. Each monitor includes dual ports for extended low-frequency response.

Seismic Audio backs each monitor with a one-year warranty. Professional-grade monitoring at a price that works for working musicians.

Frequently Asked Questions

What amplifier power do I need for the SA-15M monitors?

Match each monitor with an amplifier channel rated between 200-350 watts RMS at 8 ohms. This provides clean headroom without risk of clipping distortion. Most guitar amp heads, powered mixers with monitor outputs, or dedicated monitor amplifiers work well. Avoid underpowering these monitors as weak amplifiers clip more easily and can damage speakers.

How many people can hear these monitors in a venue?

These monitors work best for stages serving audiences of 50-150 people. They're designed as personal or section monitors for performers, not main PA speakers for the audience. For larger venues, you'll want dedicated main speakers while using these SA-15Ms strictly for stage monitoring.

Do I need a subwoofer with these floor monitors?

No, the 15" drivers provide sufficient low-end response for most monitoring applications. These monitors extend down to 40Hz, covering the fundamental frequencies of bass guitar and kick drum. Add a subwoofer only if you're using these as part of a main PA system rather than dedicated stage monitors.

What cables do I need to connect these monitors?

Use standard 1/4" TS (tip-sleeve) speaker cables, not instrument cables. Run speaker cable from your amplifier's monitor outputs to the dual 1/4" inputs on each monitor. The dual inputs allow daisy-chaining to additional monitors if needed. Never use XLR or 1/4" TRS instrument cables for speaker connections.

Can I use these monitors as main PA speakers?

While possible for very small venues, these monitors are optimized for stage monitoring with their wedge angle and frequency response. For main PA use, consider Seismic Audio's full-range speakers designed for audience coverage. Use the SA-15M pair for their intended purpose as floor monitors to get the best performance and clarity for performers on stage.
