Active Compliance Management (ACM) Patent Pending
ACM is a unique hybrid design that combines the attributes of direct radiating and band-pass configurations to reduce distortion and optimize amplitude and phase response

Sounds like they are using some type of Positive Feedback arrangement, as in ACEBass etc to alter the T/S.
From the specs i saw, it's not as effecient, nor produces as much SPL as some designs we're familiar with ! Still, i havn't heard it, so it "might" sound ok ?
Is HR capable of simming this ?
@ Inductor
Yeah it's a hybrid i just wondered about the best way to sim it ? As nobody else has replied, i guess they don't know !
Thanks for the Andre d'Alton link, i'm looking at it now Amazing to think it was filed in 1933 ! I have a feeling not many people knew about it @ the time, or until many years later. Fig 1 is how many boxes are still being built, even after 80 Years !
Around a year earlier Albert L. Thuras of Bell Laboratories patented the Bass Reflex ! Maybe AdA saw that & expanded on it ?
So 2 great designs from 2 clever people from way back when, that have influenced speaker designs ever since. And to think, they had NO software or high tech hardware to do what they did. Fantastic
