The Magma-215 delivers professional-grade output for bands, DJs, and venues that need serious low-end punch without compromising clarity. This dual 15" passive loudspeaker cabinet handles both bi-amp and full-range operation, making it adaptable to different sound system configurations.

Built around two high-performance 15" woofers with 3" voice coils and 75 oz magnets, the Magma-215 produces deep, controlled bass response down to 45 Hz. The 1.375" titanium compression driver with wide dispersion horn ensures vocal and instrumental clarity reaches every corner of your venue with 90° x 60° coverage.

With 1000 watts RMS power handling and 132 dB maximum SPL, this cabinet moves serious air while maintaining headroom for dynamic peaks. The switchable crossover design lets you run it as a standalone full-range speaker or split frequencies for bi-amp operation. At 4 ohms impedance with dual Speakon inputs, it integrates seamlessly with professional amplifiers and crossover systems.

The Magma-215 handles medium to large venues — think clubs, outdoor festivals, or church sanctuaries seating 400-600 people. Twelve M10 flying points allow permanent installation or suspended arrays for larger coverage areas. The rugged MDF construction with textured finish and steel grille stands up to regular transport and setup.

Connect via standard Speakon cables to your amplifier or crossover system. Side pocket handles ease transport despite the 97-pound weight. Seismic Audio backs the Magma-215 with a one-year warranty and ships quickly to get your sound system running.

Frequently Asked Questions

What size venues work best with the Magma-215?

The Magma-215 handles medium to large venues seating 400-600 people indoors, or outdoor events up to 800-1000 people depending on coverage requirements. Its dual 15" configuration and 132 dB maximum output provide enough headroom for live bands, DJ sets, or speaking events in clubs, churches, or festival stages. For smaller venues under 200 people, a single 15" model might be more appropriate.

Can I run the Magma-215 in both bi-amp and full-range modes?

Yes, the Magma-215 features a switchable crossover that allows both bi-amp and full-range operation. In bi-amp mode, you'll need separate amplifiers for the highs and lows, giving you more control over each frequency range. Full-range mode lets you run a single amplifier to the cabinet, making setup simpler for portable applications. The crossover points are set at 800 Hz and 2.5 kHz.

What amplifier power do I need for the Magma-215?

The Magma-215 handles 1000 watts RMS at 4 ohms impedance, so you'll want an amplifier capable of delivering at least 1000-1200 watts at 4 ohms for full headroom. Most professional power amplifiers in the 1500-2000 watt range will drive this cabinet effectively. Make sure your amplifier is stable at 4 ohms and use quality Speakon cables for the connection.

Do I need a subwoofer with the Magma-215?

The dual 15" woofers provide substantial bass response down to 45 Hz, which covers most musical content without additional subwoofers. However, if you're running electronic music, hip-hop, or other bass-heavy genres, adding dedicated subwoofers will enhance the very low frequencies below 50 Hz. For rock, country, or acoustic music, the Magma-215 typically provides sufficient low-end on its own.

How do the flying points work for permanent installation?

The twelve M10 flying points allow professional rigging for permanent installations or suspended arrays. You'll need appropriate hardware rated for the 97-pound weight plus safety factors, and installation should be performed by qualified riggers. The flying points enable various mounting angles and cluster configurations for optimal coverage in fixed installations like theaters, churches, or clubs.
