Electro Dynamic Braking in Mirage M3-si


Can anyone elaborate what Electro Dynamic Braking in Mirage M3-si's 10inch woofer is please?
Or to point to a resource (brochure?) online where I can read/download about it?

This tech was also in M7-si but absent in top of the line (which is strange) M1-si (and also absent in M5-si).
Also, the first M series (without 'si') had no Electro Dynamic Braking on the woofer (none of the models).

I found this info in the original Mirage Msi brochure and I am very curious to find out what it is. 
Is this something to do/similar to servo controlled woofers?
Does it benefit the woofer control in real life? Why Mirage wouldn't use it in top of the line M1-si though?

many thanks
Marketing. At any rate it is a design that has been shunned by the vast majority of speaker manufacturers. Blasting sound all over the place is the best way to create confused room acoustics. Pedestrians like the effect. Look how many Bose 901s were sold. One of the worst speakers ever made. Us audio aficionados died laughing. What snobs we are. I actually have an older set of Mirage speakers. Don't remember the model. They are 3 way with two 10" woofers in each. I have 4 of them in my workshop and I have been blasting the hell out of them for 25 years. Speaker competes with 14 inch radial arm saw. I reckon I can't complain.   
with all due respect, I am not interested in your subjective opinion on M3si at all. As you may, or rather may not, see from the topic of this thread I am interested in EDB tech.

Please create a worthwhile content and input by answering the question or, in case you don't know,.....don't write anything at all to avoid spamming.Thank you

I am not sure if it is the same thing that Legacy used in some of their older models such as Signature III. They called it dynamic braking if memory serves. Basically, they had a dual voice coil woofer and used the back EMF from the first coil and shorted it into the second coil. It supposedly helped control woofer motion under high power usage. The M-3si woofer is a dual voice coil design. I am not sure if they were doing something similar with it or not. 
I don't know how dipolar, bipolar, open baffle, or omni-directional speakers have been shunned. They all send sound into the room in more than one direction. Magnepan, Martin-Logan, Sanders, Murr Audio, Quad, Kingsound, Sound Lab, Ohm, German Physics, Spatial, Emerald Physics, Pure Audio Project, GR Research, Linkwitz, etc, are all currently manufactured speakers that send the acoustic wave both forward and backward into the room. I guess no one listens to any of them. I guess when you have listened to a radial arm saw for long enough, everything sounds the same.
Many thanks for your comment - useful hint about the EDB. 
Although looking at the said woofer:

it doesn't look like having dual voice coil design (I am even surprised to see that the coil itself is so small).
Ps. I have of course emailed Klipsch (company who took over Mirage) to get an answer and they were useless. They told me they 'don't know'
All woofers and midrange drivers in the new M Series use injection-molded polypropylene cones impregnated with carbon and other proprietary additives for increased strength and rigidity. The woofer surround is still Butyl rubber, but the magnet is heavier: 28oz in the M-3si compared to the 20oz magnet in the M-3. This, along with a dual (or second) winding on the voice-coils of the woofer and tweeter (the latter also sports a heavier magnet), is said to lower distortion and increase power handling. The woofer is designed and built in-house; the midrange and tweeter are designed at Mirage, but built elsewhere. As in the M-3, the M-3si features matched pairs of back-to-back PTH tweeters and midrange drivers (with the rear-radiating sound delivered in-phase with the direct output from the front), but uses a single, front-mounted, ported 10" woofer.

I hadn't seen the woofer before. The above excerpt is from the Stereophile review of the M3si and is where I got the information from. Maybe I interpreted what was stated incorrectly.
"dual (or second) winding on the voice-coils of the woofer and tweeter" in Stereophile review.....how on earth did I miss that bit? :)

Many thanks for point out tho. Useful clue. 

Still waiting for someone to clearly explain and/or point to some materials online for what exactly EDB is and how it works in real life. thanks
Sorry I stepped on you toes meekeenz. But I did answer your question first. I said marketing. Dual voice coil woofers have been around for ever and if you hook one coil up the the other backwards all you will get is burned out fuses and voice coils. More BS is spewed about speaker design and mythology to try and distinguish ones products from another's. You can't find anything because there is nothing. It is all just a figment of some marketer's brain who probably does not know squat about speaker design.

Ian Paisley designed the M3si. Maybe he can be contacted directly through this site. Good luck.
Thanks csmgolf

I was thinking of contact him directly already and......tried to search for him on Facebook and LinkedIn to no avail hehe. 

I have already emailed Soundstage Audio now to ask for his email address. We will see what they say. 
It is just strange that there is no info on this tech anywhere on the internet or in the reviews and no one knows what it is about.
no luck here I suppose
This is strange
