The Magma-15 pair delivers professional full-range sound for bands, DJs, and venues that need reliable PA speakers without breaking the budget. These passive 2-way cabinets handle both mains and monitor duties, making them versatile workhorses for live sound applications.

Each cabinet puts out serious volume with 500 watts RMS and 1000 watts peak power handling, driven by a 15-inch woofer with a hefty 75 oz magnet and 3-inch voice coil. The titanium compression driver and wide dispersion horn provide clear highs with 90° x 60° coverage pattern.

The switchable crossover design lets you run these speakers in full-range passive mode or bi-amp configuration for more control over your mix. At 8 ohms impedance with dual Speakon inputs, they integrate easily into existing PA systems. Frequency response spans 48 Hz to 19 kHz with 99 dB sensitivity, delivering full-bandwidth sound that reaches 130 dB maximum SPL.

Use them for band performances in clubs and theaters seating up to 300 people, DJ gigs at weddings and corporate events, or as floor monitors for stage performers. The trapezoidal MDF enclosure works upright for mains or angled for monitoring, while 12 M10 flying points enable permanent installation or temporary rigging.

Connect via Speakon cables to your amplifier or powered mixer. Each cabinet weighs 55 pounds and includes side handles for transport.

Seismic Audio backs the Magma-15 pair with a one-year warranty and ships nationwide to get your sound system up and running fast.

Frequently Asked Questions

What size venues can the Magma-15 pair handle?

These speakers work well for indoor venues up to 300 people, such as clubs, small theaters, wedding receptions, and mid-size conference rooms. For outdoor events, expect effective coverage for crowds of 150-200 people depending on ambient noise and setup. The 130 dB maximum SPL and 99 dB sensitivity provide enough headroom for most live music and DJ applications.

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

You'll need Speakon to Speakon cables to connect from your amplifier or powered mixer to each speaker. Each cabinet has dual Speakon inputs for daisy-chaining or bi-amp operation. Standard quarter-inch cables won't work with these speakers - Speakon connections are required for the power levels these cabinets handle.

Can I use these speakers as both mains and monitors?

Yes, the trapezoidal design works perfectly for both applications. Set them upright on poles or stands for main PA duties, or angle them back as floor monitors for stage performers. The 90° x 60° coverage pattern provides good dispersion whether positioned vertically or as wedge monitors, making them versatile for different live sound setups.

Do I need a subwoofer with the Magma-15 pair?

For most applications, these full-range speakers provide sufficient low-end extension down to 48 Hz. However, if you're doing DJ work with heavy electronic music or need more sub-bass for larger crowds, adding a subwoofer will enhance the overall system impact. The switchable crossover also allows you to bi-amp and use an external crossover for more precise frequency management.

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

Full-range mode uses the internal passive crossover to split frequencies between the woofer and tweeter - just connect one cable from your amp. Bi-amp mode bypasses the internal crossover, letting you use separate amplifiers for the low and high frequencies through an external crossover. Bi-amping gives you more control and potentially better performance but requires additional amplification and processing equipment.
