The SA-12MT-PW pair delivers professional stage monitoring for bands, solo performers, and live sound engineers who need reliable foldback in venues up to 400 people. These powered wedge monitors put your vocals and instruments right where you need them—clearly audible over stage volume without feedback issues.

Each monitor pumps 300 watts RMS through a 12-inch woofer and 1.35-inch titanium compression driver, covering the full 40Hz to 20kHz frequency range at 123dB maximum SPL. The titanium horn delivers crisp highs that cut through dense mixes, while the ported 12-inch driver provides punchy midrange and enough low-end response for vocals, guitars, and keyboards without muddiness.

The Class D amplifier keeps weight down to 38.6 pounds per cabinet while delivering clean power. Onboard 3-band EQ lets you dial in the perfect monitor mix for different instruments or vocal ranges. The angled wedge design projects sound directly to performers' ears from floor level, and the low 24.25-inch profile won't block audience sightlines.

Connect via XLR inputs with loop-through outputs for daisy-chaining multiple monitors from a single console send. The 3.5mm input handles direct connection from phones or laptops for solo performers. Each monitor includes recessed handles for easy load-in and black carpet covering with metal corners for durability on the road.

Seismic Audio backs these monitors with a one-year warranty and ships nationwide. Professional-grade monitoring that works every night without breaking the budget.

Frequently Asked Questions

What size venue can these monitors handle?

Each SA-12MT-PW monitor delivers 123dB maximum SPL, making them suitable for venues up to 400 people or outdoor stages where performers need to hear over high stage volume. The 300-watt RMS power rating provides plenty of headroom for vocals, acoustic instruments, and keyboard monitoring without distortion. For larger venues or louder rock bands, consider adding more monitors rather than pushing these beyond their limits.

What cables do I need to connect these monitors?

You'll need standard XLR microphone cables to connect from your mixing console's monitor sends to the monitors' XLR inputs. Each monitor has XLR loop-through outputs, so you can daisy-chain multiple monitors from a single console output using additional XLR cables. The 3.5mm input lets solo performers connect phones, laptops, or audio interfaces directly without needing a mixing console.

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

While these are designed as floor monitors, they work well as small PA speakers for acoustic performances, coffee shops, or meeting rooms up to 100 people. The wedge angle projects sound upward when used as monitors, but they'll still cover a room effectively when placed on stands or tables. For dedicated main PA use, consider Seismic's full-range PA speakers designed specifically for audience coverage.

Do I need a subwoofer with these monitors?

Not for typical stage monitoring applications. The 12-inch ported design provides enough low-end for vocals, guitars, keyboards, and most instruments that performers need to hear in their monitor mix. Bass players might want to add a powered subwoofer for their personal monitor rig, but most performers will find these monitors deliver sufficient full-range coverage for effective stage monitoring.

How do these compare to passive monitors?

These powered monitors eliminate the need for separate amplifiers, reducing cable runs and setup complexity. The built-in Class D amp is matched specifically to the drivers for optimal performance and protection. The onboard EQ lets each performer customize their monitor sound without affecting others. Passive monitors require external amplification but offer more flexibility in amp selection and potentially lower per-unit costs for larger systems.
