or… Doc Brown in Back to the Future saying, “I finally invented something that works!” Speaking in reference to the Flux Capacitor. Nah, it’s nothing of the sort, but it is by no means less cool. The Flux Density Modulation Speakers are a new approach to attenuation where the attenuation happens right at the speaker! Giving you up to -9 dB attenuation, while keeping your tone, that is what I call cool, and something I must check out! You know me, I’m an attenuator fan, and something like this has me absolutely GAS-ing! From what I could tell from the videos below, the tone is really preserved. Now, mind you that -9 dB of attenuation won’t get you down to conversation levels, but it’ll sure provide enough attenuation to take the bite off the volume. If you need to go lower, hell! Get an Aracom attenuator, and get it down REAL LOW! Check out the NAMM vids!

Cool! I love new technologies and innovations like this. It’s amazing that no one has figured out how to do this until almost 60 years after guitar amps were becoming commonplace. There is a company called FluxTone Speakers which designed a similar speaker system last year. Their speakers can attenuate the output by 25dB, but it comes at a huge price tag of $750 and up. I hope Eminence can cut costs enough to make this technology affordable to everyone.
I’m pretty sure that they’ll be much less. The problem with Fluxtones as I see it is that they are active devices that need a power supply, in addition to being priced way too high for most folks.
While the Eminence speakers only attenuate down to -9dB, that’s enough to really take the edge off of a loud amp. To me, that’s really usable.
According to Eminence, they bleed highs a little, and after watching/listening to the videos again, I noticed that, but it’s such a small amount that it doesn’t matter. I’m definitely going to check one of these out!
