Magma-212 - Premium Dual 12" Full Range / Bi-Amp 2-Way Loudspeaker Cabinet

$432.99 $623.99

The Magma-212 is built for bands, DJs, and venues that need serious sound reinforcement without the complexity of powered speakers. This dual 12-inch passive cabinet delivers the low-end punch and vocal clarity that cuts through loud stages and energetic crowds.

Two high-performance 12-inch woofers with 50-ounce magnets and 3-inch voice coils handle bass and midrange duties, while a 1⅜-inch titanium compression driver with wide dispersion horn ensures vocals and highs reach every corner of your venue. The bi-amp/full-range switchable crossover gives you flexibility to run it passive from a single amplifier or bi-amp it for maximum control and power handling.

With 600 watts RMS power handling and 120 dB maximum SPL, this cabinet covers venues up to 400 people indoors. The 90° x 60° coverage pattern provides even sound distribution whether you're using it as a main PA speaker or stage monitor. Twelve M10 flying points allow for permanent installation or rigging applications where floor space is limited.

Two Speakon inputs handle connections from your power amplifier. The 4-ohm impedance works efficiently with professional amplifiers, while the ported design extends low-frequency response down to 45 Hz. The rugged MDF cabinet with textured black finish and powder-coated steel grille stands up to regular transport and setup.

Seismic Audio backs the Magma-212 with a one-year warranty and ships it ready to connect to your amplifier and start performing.

Frequently Asked Questions

What size venues can the Magma-212 handle?

The Magma-212 covers venues up to 400 people indoors with its 120 dB maximum SPL and efficient 90° x 60° dispersion pattern. For outdoor events, expect coverage for 200-250 people due to the lack of acoustic boundaries. The dual 12-inch configuration provides the low-end impact needed for music venues, while the titanium compression driver ensures speech intelligibility in houses of worship or corporate spaces.

What amplifier do I need to power this speaker?

You'll need an external power amplifier capable of 600-1200 watts at 4 ohms to properly drive the Magma-212. The bi-amp/full-range switch lets you run it from a single stereo amplifier channel in full-range mode, or use two amplifier channels in bi-amp mode for maximum control and power handling. Connect your amplifier to the speaker using professional speaker cables with Speakon connectors.

Can I use this as both a main PA speaker and a monitor?

Yes, the Magma-212 works well as either a main PA speaker or stage monitor. The wedge-shaped profile and side pocket handles make it easy to position as a floor monitor, while the twelve M10 flying points allow for main PA positioning on stands, poles, or rigged installations. The wide 90° horizontal dispersion provides even coverage whether positioned upright or angled on the floor.

How does the bi-amp mode compare to full-range operation?

Bi-amp mode uses separate amplifier channels for the woofers and compression driver, giving you independent EQ control and more efficient power distribution. Full-range mode runs the entire speaker from one amplifier channel through the internal passive crossover, which is simpler to set up but gives you less control over the sound. Most users start with full-range mode and upgrade to bi-amping when they need more precise sound shaping.

Do I need a subwoofer with the Magma-212?

The dual 12-inch woofers extend down to 45 Hz, providing substantial low-end for most live sound applications without a subwoofer. However, if you're playing bass-heavy music genres like hip-hop or EDM, or covering large venues over 300 people, adding a dedicated subwoofer will give you the deep bass impact those applications demand. The Magma-212's ported design complements subwoofers well when you're ready to expand your system.
