The GH15M passive wedge monitors deliver professional stage monitoring for bands, DJs, and live performers who need to hear themselves clearly during performances. These floor monitors work with any amplifier or powered mixer to provide focused sound directly to performers on stage.

Each 15-inch monitor handles 400 watts RMS with a frequency response from 45 Hz to 20 kHz, giving you the full range needed to monitor vocals, instruments, and backing tracks. The high-output ribbed cone woofer paired with a 1-inch horn tweeter creates balanced sound that cuts through stage noise without feedback issues.

The 8-ohm impedance makes these monitors easy to daisy-chain from a single amplifier channel, while dual input options let you connect via 1/4-inch cables or direct speaker wire. At 96 dB sensitivity, they deliver plenty of volume without requiring massive amplifier power. The wedge design angles sound up toward performers while the tuned bass reflex port extends low-frequency response.

Built for the road with aviation-grade carpet covering, steel mesh grilles, and reinforced ABS corner guards, these monitors handle the bumps and drops of mobile gigs. Each monitor weighs 34 pounds and measures 25" x 18" x 14", making them manageable for solo setup while still delivering the punch needed for small to mid-sized venues up to 200 people.

Connect directly to your amplifier's speaker outputs using standard speaker cables. The pair ships ready to use with no additional accessories required.

Seismic Audio backs these monitors with a comprehensive warranty and ships from multiple US warehouses for fast delivery to get your monitoring system up and running quickly.

Frequently Asked Questions

What amplifier power do I need for these monitors?

These monitors handle 400 watts RMS each, so you'll want an amplifier that delivers at least 200-300 watts per channel at 8 ohms for clean headroom. A 500-600 watt per channel amp gives you plenty of power for loud stages. Remember that underpowering speakers causes more damage than overpowering them, as long as you don't drive the amp into clipping.

Can I daisy-chain multiple monitors together?

Yes, the 8-ohm impedance makes these monitors perfect for daisy-chaining. You can connect two monitors per amplifier channel (resulting in 4-ohm load) or even four monitors total across two channels. Use the parallel 1/4-inch inputs or speaker wire terminals to chain them together with standard speaker cables.

What size venues are these monitors good for?

These 15-inch monitors work well for small to medium venues up to 200 people, including clubs, churches, school auditoriums, and outdoor events. They provide enough volume for most band applications without needing a subwoofer, though adding one will extend the low end for bass-heavy music or DJ applications.

Do I need a subwoofer with these floor monitors?

For most band monitoring applications, these 15-inch monitors provide sufficient low end down to 45 Hz without a subwoofer. However, if you're monitoring bass-heavy electronic music, hip-hop, or want that extra low-end thump for kick drums and bass guitar, adding a subwoofer will enhance the experience.

What cables do I need to connect these monitors?

You'll need standard speaker cables to connect from your amplifier's speaker outputs to the monitors. You can use either 1/4-inch speaker cables (not instrument cables) or raw speaker wire with the spring-loaded terminals. For daisy-chaining, use additional speaker cables between monitors. Instrument cables will not work properly and may damage your equipment.
