The SA-15MX floor monitor delivers clear vocal reproduction and instrument reinforcement for bands, solo performers, and houses of worship that need reliable stage monitoring. This 2-way passive monitor combines a 15" woofer with a 7x9 titanium horn tweeter to provide balanced sound reproduction across vocals and instruments.

Built around a 15" driver with a 50-ounce magnet and 2.5" voice coil, the SA-15MX handles 350 watts RMS and 700 watts peak power. The titanium horn tweeter ensures vocalists and musicians hear clear detail in the critical midrange and high frequencies where intelligibility matters most.

The 45Hz to 20kHz frequency response covers the full range of musical content, while the 8-ohm impedance and 95dB sensitivity work efficiently with most power amplifiers. The rear-ported cabinet design extends low-frequency response without sacrificing clarity. At 54 pounds with a durable black carpet finish and metal corner protection, this monitor withstands regular transport and stage use.

Whether you're running monitors for a four-piece band, providing vocal reinforcement for a worship team, or setting up DJ monitoring for mobile gigs, the SA-15MX handles venues up to 200 people. The angled cabinet design ensures proper positioning when placed on the floor, directing sound toward performers' ears.

Dual 1/4" and dual Speakon inputs provide flexible connection options for any amplifier or powered mixer output. The monitor includes a standard pole mount socket for speaker stand mounting when needed.

Seismic Audio backs the SA-15MX with a one-year warranty and direct shipping from our warehouse.

Frequently Asked Questions

What size venue can the SA-15MX handle as a floor monitor?

The SA-15MX works well for monitoring in venues up to 200 people, including small to medium churches, club stages, and wedding reception spaces. For larger venues, you may want multiple monitors or consider pairing with a subwoofer for extended low-end response.

What cables do I need to connect the SA-15MX to my amplifier?

You'll need either a 1/4" speaker cable or a Speakon cable to connect from your power amplifier to the monitor. The SA-15MX has dual inputs of each type, so you can use whichever cable type your amplifier provides. Never use instrument cables or XLR cables for speaker connections.

Can I use the SA-15MX as a main PA speaker instead of just a monitor?

While designed as a floor monitor, the SA-15MX can work as a main speaker for smaller venues when mounted on a speaker stand using the pole mount socket. For main PA use, consider adding a subwoofer to extend the low-frequency response for fuller sound coverage.

How many SA-15MX monitors do I need for a typical four-piece band?

Most four-piece bands use 2-4 monitors depending on stage size and individual preferences. Start with two monitors positioned for the vocalist and lead instruments, then add more based on each musician's monitoring needs. Drummers often benefit from a dedicated monitor for click tracks or vocals.

What power amplifier do I need to drive the SA-15MX properly?

The SA-15MX works with amplifiers rated between 250-500 watts RMS at 8 ohms. This gives you clean headroom without risk of damaging the speaker. Most powered mixers with 300+ watts per channel will drive the SA-15MX effectively for typical stage monitoring applications.
