The SA-15M.3 delivers professional stage monitoring for bands, vocalists, and performers who need reliable feedback in venues up to 200 people. This wedge-style floor monitor handles both stage monitoring duties and main PA applications with equal capability.

Built around a 15-inch woofer with 50 oz magnet and 2.5-inch voice coil, this monitor pushes 250 watts RMS through a frequency range of 45Hz to 20kHz. The 4x10 piezo horn tweeter ensures vocal clarity cuts through stage volume, while dual ports enhance low-frequency response for fuller sound reproduction.

The 8-ohm impedance and 96dB sensitivity make this monitor easy to drive with most amplifiers and mixing boards. Dual 1/4-inch inputs allow daisy-chaining multiple monitors or running separate mixes to the same unit. The wedge design positions at the optimal angle for stage monitoring, though it can flip to either side for different angles.

Use this monitor for band rehearsals, small to medium venues, church sound systems, or DJ setups where performers need to hear themselves clearly. The included pole mount transforms it into a main PA speaker for events up to 150 people. Front-panel plywood construction with steel grille and metal corners handles the rigors of regular transport and setup.

Connect directly to your mixer's monitor outputs using standard 1/4-inch speaker cables. The top-mounted strap handle makes positioning quick and easy. Backed by Seismic Audio's one-year warranty with fast shipping to get your sound system running.

Frequently Asked Questions

What size venue can this monitor handle as a main speaker?

As a main PA speaker on the included pole mount, the SA-15M.3 works well for indoor venues up to 150 people or outdoor spaces up to 100 people. For larger crowds, pair it with a subwoofer or use multiple units. The 250 watts RMS provides enough clean power for most small to medium events like church services, wedding receptions, or club performances.

What cables do I need to connect this monitor?

You'll need standard 1/4-inch speaker cables to connect from your mixer's monitor output or amplifier to the monitor. The dual inputs allow you to daisy-chain multiple monitors using a second speaker cable, or run two different mixes to the same unit. Speaker cables are sold separately and should match the length needed for your setup.

Can I use this for drum monitoring or does it handle low frequencies well?

Yes, this monitor handles drum monitoring effectively thanks to the 15-inch woofer and dual-port design that extends low-frequency response down to 45Hz. The larger driver size compared to 12-inch monitors gives you more punch for kick drum and bass guitar. Many drummers prefer 15-inch monitors for the fuller low-end reproduction.

How does this compare to using a 12-inch monitor?

The 15-inch driver provides more low-frequency response and overall volume than a 12-inch monitor, making it better for full-band monitoring or when you need to hear bass instruments clearly. However, it's heavier at 39 pounds versus typical 12-inch models around 30 pounds. Choose 15-inch if you prioritize fuller sound and have the transport capacity.

Do I need a separate amplifier or does this monitor have built-in power?

This is a passive monitor that requires an external amplifier or powered mixer to drive it. Connect it to your mixer's amplified monitor outputs, a dedicated monitor amplifier, or the speaker outputs of a powered mixer. The 8-ohm impedance makes it compatible with most amplifiers, and the 250-watt RMS rating tells you the minimum amplifier power recommended.
