Seismic Spotlight: Magma Series Powered PA Speakers

The Magma series of PA speakers are the premium choice from the Seismic Audio stable.  Built to rigorous standards, these speakers are solid enough to stand up to a lifetime of gigs.  Each powered cabinet is matched to a purpose-built amplifier ensuring consistent sound quality every time.  The single speaker cabinets, passive and active, are designed with trapezoidal cabinets.  This shape allows them to easily be used as monitors, as well as PA loudspeakers.  These cabinets also include pole mounts for standard PA use and a dozen M8 flying points if your venue needs the PA to be flown.  All full-range cabinets boast a 90 degree by 60 degree coverage pattern making them capable of covering any area easily.

Let’s dig a little deeper on the individual models and learn more about the Magma series.



1600 Watts of Peak power through an 18″ speaker with a 4″ voice coil provides all the low end you need in one cabinet.  The Class AB amplifier will stand up to whatever you throw at it in any genre.  The cabinet is built from medium density fiberboard and a powder-coated full metal grill.  This speaker is solid.  Helpful features like a Phase / Invert switch and an XLR Loop Through output, make the Magma-118S-PW ideal for anyone who needs a top-tier powered subwoofer.






Need more loud?  This speaker will hit 135 dB thanks to 1000 watts RMS running through two 15″ woofers and 1 3/8″ titanium horn designed for wide dispersion.  Massive 75 ounce magnets and 3″ voice coils reside inside a sturdy medium density fiberboard cabinet.  The grill is powder coated steel and will stand up to the worst abuse.  Bi-Amping allows the whole package to be more efficient.
