The SA-12MT-PW powered floor monitor delivers clear vocal and instrument reproduction for performers who need to hear themselves on stage. This 12-inch wedge-style monitor works for bands, solo acts, DJs, and speaking applications where stage monitoring is essential.

The 300-watt RMS Class D amplifier drives a 12-inch woofer and 1.35-inch titanium compression driver, producing clean sound from 40 Hz to 20 kHz at up to 123 dB SPL. The titanium horn handles vocal frequencies with clarity while the ported design extends low-end response for full-range monitoring.

The built-in 3-band EQ (treble, mid, bass) and gain control let you dial in the right balance for your voice or instrument. Dual-voltage operation (110-240V) handles any power situation, while the crossover point at 2.5 kHz keeps vocals clear and present in the mix.

Use this monitor for club gigs up to 200 people, church stages, outdoor events, or studio applications. The wedge design angles sound toward performers while minimizing feedback, and multiple units can be daisy-chained for larger setups or multi-performer monitoring.

Connect via XLR input/output or the 3.5mm aux input for backing tracks from phones or tablets. The side-mounted control panel stays accessible when the monitor is positioned on stage. MDF construction with 5/8-inch plywood baffle and metal corner protection handles regular transport and stage use.

Seismic Audio backs this monitor with a one-year warranty and ships ready to use for professional live sound applications.

Frequently Asked Questions

How loud is this monitor and what size venues will it handle?

The SA-12MT-PW produces up to 123 dB SPL, making it suitable for club gigs, church stages, and outdoor events up to 200 people. The 300-watt RMS power rating provides enough clean headroom for most live sound applications where stage monitoring is needed. For larger venues or louder bands, consider using multiple monitors or adding a subwoofer for extended low-end support.

What cables do I need to connect this monitor?

You'll need standard XLR cables to connect from your mixer's monitor send to the monitor's XLR input. The monitor includes XLR output for daisy-chaining to additional monitors if needed. For backing tracks or solo performance, use a standard 3.5mm to 3.5mm cable from your phone or tablet to the aux input. No additional power cables are required beyond the included AC cord.

Can I use this as a main PA speaker instead of just a monitor?

While this monitor can function as a small PA speaker, it's optimized for stage monitoring with its wedge design and angled dispersion pattern. For main PA use, consider Seismic Audio's full-range speakers that project sound forward to the audience. The SA-12MT-PW works best when angled up toward performers rather than projecting horizontally to a crowd.

How do I prevent feedback when using this monitor on stage?

Position the monitor behind microphones and away from direct pickup patterns. Use the onboard 3-band EQ to cut problematic frequencies - often reducing mids around 800 Hz to 2 kHz helps control feedback. Keep monitor volume below the threshold where feedback occurs, and consider using a feedback suppressor or graphic EQ in your signal chain for additional control.

Does this monitor need a subwoofer for full-range sound?

The SA-12MT-PW's frequency response extends down to 40 Hz, providing adequate low-end for most monitoring applications including vocals, guitars, and keyboards. For bass guitar monitoring or electronic music with deep sub-bass content, adding a subwoofer will provide fuller low-frequency response. Most performers find the monitor's built-in bass response sufficient for stage monitoring without additional subwoofers.
