A full 18" unit, Maelstrom delivers the highest displacement in a single high efficiency, low frequency driver available for under $300.
A dual 8 ohm voice coil unit, it's capable of extreme levels of bass in a variety of enclosures. Essentially, Maelstrom is a full-blown pro sound woofer, optimized to cover the entire first octave. Most pro-sound woofers roll-off around 30-40 Hz; other high excursion 18s trail off in the 25-30 Hz range, and can't extend beyond a few hundred Hz. Maelstrom's been designed to offer the same level of dynamics, clarity, and high frequency extension as the best pro-sound woofers, but with the ability to crank out serious SPLs below 20 Hz.
