Eminence Speaker introduces Flux Density Modulation

Eminence Speaker introduces Flux Density Modulation (FDM) Technology, a tonal breakthrough for guitar sound. The patent pending FDM Technology from Eminence offers control of output level, associated distortion, and tonal balance via a simple control knob on the back of the speaker.
Since electric guitars first hit the stages of entertainment venues cranking out Blues and Rock'n'Roll, guitarists have struggled to maintain a balance of the saturated, overdriven tone of a great tube amplifier and a reasonable stage volume. "The dilemma has spawned the development of isolation chambers, isolation boxes, electronic attenuators and a host of other compromises that just don’t lend the same tone and feel as a good high-power tube amp cranked up to 10," said Eminence Speaker LLC President, Chris Rose. "Eminence is proud to present what could be the most notable development in guitar loudspeaker technology in decades."
Eminence engineers have collaborated to introduce a simple, affordable 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.

"Using a speaker without attenuation circuits or other gadgets to facilitate amplifier distortion is the most logical engineering solution to an age old problem,” said Tom James, Design Engineer at Eminence. "Our method maintains fidelity in the signal path that can otherwise be compromised. The ability to adjust a speaker's output in this manner simplifies life for today's musician playing varied styles in a spectrum of venues."
This all-analogue technology puts a new twist on guitar tone. Turning the modulator knob to adjust speaker output and amplifier interaction helps finding that sweet spot of saturated tube tone - but at a significantly lower volume. Available in both the Patriot and Red Coat lines of Eminence guitar speakers, the Maverick and ReignMaker models each add this tonal control.
