This 15" full-range speaker handles 500 watts RMS (1000 watts peak) with a frequency response of 48 Hz to 19 kHz, providing solid low-end punch and clear highs for vocals and instruments. The titanium compression driver with wide dispersion horn covers a 90° x 60° pattern, ensuring even sound distribution across your audience.

The cabinet features dual Speakon inputs and switchable crossover modes for full-range passive or bi-amp operation, giving you flexibility in how you power and process your signal. At 99 dB sensitivity and 8-ohm impedance, it pairs efficiently with most power amplifiers.

Frequently Asked Questions

What size venue can the Magma-15 handle?

The Magma-15 works well for indoor venues up to 300 people when used as a main PA speaker. For larger spaces or outdoor events, pair it with a subwoofer or use multiple cabinets. The 130 dB maximum SPL and wide 90° x 60° coverage pattern provide good sound distribution for medium-sized clubs, churches, and event spaces.

What cables do I need to connect the Magma-15?

You'll need Speakon-to-Speakon cables to connect from your power amplifier to the speaker. The cabinet has dual Speakon inputs for daisy-chaining multiple speakers or bi-amp operation. Standard 1/4" speaker cables won't work with this cabinet - Speakon connections are required for proper operation.

Can I use this speaker as a floor monitor?

Yes, the trapezoidal cabinet design allows the Magma-15 to function as both a main PA speaker and a floor monitor. When positioned on its side as a monitor, the angled enclosure aims the sound upward toward performers on stage. The side handle makes repositioning easy during setup.

Do I need a subwoofer with the Magma-15?

For most applications, the 15" woofer provides adequate low-end response down to 48 Hz. However, if you're playing bass-heavy music, electronic dance music, or need more sub-bass impact, adding a dedicated subwoofer will enhance the overall system performance. The cabinet works well as a satellite speaker in larger PA systems.

What's the difference between bi-amp and full-range mode?

Full-range mode uses the internal crossover to split frequencies between the woofer and tweeter - just connect your amplifier to one input. Bi-amp mode bypasses the internal crossover, allowing you to use separate amplifiers and external crossover processing for the high and low frequencies. This provides more control over your sound but requires additional equipment.
