Eminence engineers have collaborated to introduce a simple, affordable, yet revolutionary technology to mechanically manipulate the flux path and relative densities within a loudspeaker motor structure. The result is a patent-pending innovation lending guitarists the ability to achieve high power amplifier tone at lower volumes simply with the turn of a dial on the back of the speaker. This revolutionary, all-analog technology puts a new twist on guitar tone. Just turn the modulator knob to adjust speaker output and amplifier interaction, helping you find that sweet spot of saturated tube tone but at a significantly lower volume. Tweak the knob for a wide range of tones: More attenuation affords a warmer tone while less attenuation restores volume and brightness. It’s like switching amps in the middle of the set. You get real attenuation without losing the “feel” of playing through a speaker. No pedals or expensive electronics – just a speaker, from Eminence. Available in both the Patriot® and Red Coat® lines of Eminence guitar speakers, the Maverick™ and ReignMaker™ models each put tonal control at your fingertips.
