Electro Dynamic Braking in Mirage M3-si

+mijostyn
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.
