The Magma-215 delivers serious output for bands, DJs, and venues that need full-range sound without compromise. This dual 15" passive speaker cabinet handles 1000 watts RMS and peaks at 2000 watts, making it ideal for medium to large venues where power and clarity matter.

Built around two high-performance 15" woofers with 3" voice coils and 75 oz magnets, the Magma-215 moves serious air while maintaining tight low-end control. The 1⅜" titanium compression driver with wide dispersion horn ensures vocals and highs cut through the mix with 90° x 60° coverage.

At 4 ohms impedance with 101 dB sensitivity, these cabinets work efficiently with most pro amplifiers. The switchable crossover design lets you run them full-range passive or bi-amp for maximum control, with crossover points at 800 Hz and 2.5 kHz. Maximum SPL reaches 132 dB, handling venues up to 500 people indoors or 300 people in outdoor settings.

Connect via dual Speakon inputs using standard speaker cables from your amplifier or powered mixer. The rugged MDF enclosure features powder-coated steel grille and side pocket handles for transport. Twelve M10 flying points provide professional rigging options for permanent installations.

Each cabinet weighs 97 pounds and measures 41.9" x 17.7" x 16.5". Backed by Seismic Audio's one-year warranty with fast shipping nationwide.

Frequently Asked Questions

What size venues can the Magma-215 speakers handle?

Each Magma-215 cabinet can effectively cover venues up to 500 people indoors or around 300 people in outdoor settings. The dual 15" woofers and 2000-watt peak handling provide enough output for larger clubs, wedding venues, churches, and outdoor festivals. For smaller intimate venues under 150 people, a single cabinet may be sufficient.

What amplifier power do I need for these speakers?

You'll want an amplifier that delivers 500-1000 watts RMS at 4 ohms per cabinet to properly drive the Magma-215. Running them at their full 1000-watt RMS rating will give you maximum headroom and dynamic range. Make sure your amp is stable at 4 ohms, as that's the nominal impedance of each cabinet.

Can I use these speakers without a subwoofer?

Yes, the Magma-215 is designed as a full-range system with dual 15" woofers that extend down to 40 Hz. The large drivers provide substantial low-end output that works well for most live music and DJ applications without additional subs. However, if you're doing bass-heavy electronic music or want to feel serious sub-bass, adding dedicated subwoofers will enhance the low-frequency impact.

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

Full-range mode uses the internal passive crossover to split frequencies between the woofers and compression driver - you just run one speaker cable from your amp. Bi-amp mode bypasses the crossover, letting you send separate low and high frequency signals from a crossover or DSP system. Bi-amping gives you more precise control over the sound but requires additional amplifier channels and processing equipment.

What cables do I need to connect these speakers?

You'll need Speakon-to-Speakon speaker cables or Speakon-to-1/4" cables depending on your amplifier's outputs. Each cabinet has dual Speakon inputs for daisy-chaining multiple speakers or bi-amp operation. Use 12 AWG or thicker speaker cable for runs over 50 feet to maintain proper power transfer and sound quality.
