These speakers fascinate me. Can someone explain to me their mode of action
Being an engineer, I read Zoltan's Ingenious patent before I bought mine. For the bass, the two woofers fire upward and downward into the "C" shaped hollow carbon fibre tube and are offset 180 degrees, which will dramatically increase the bass response, while at the same time cancelling the mechanical artifacts of the drivers. This C shaped tube has two rear firing ports for yet further improved bass response.
Using a 1st order crossover at 2k is where the magic REALLY starts! And where Zoltan's design separates from the all the rest.
Located in the centre front of the speaker, the dual diaphragm Bayz Radial Speaker (BRS) takes over, (which is the subject of his patent)
This ingenious dual membrane driver uses two magnetic gaps, into which the edges of the forward and rear firing cylindrical membranes are suspended. Due to the brilliant geometry (the gaps are 180 degrees apart and perpendicular to the main listening axis) the two membranes are cylindrical and approximately 270 degrees from edge to edge which are joined in the magnetic gap and are essentially pulsing, physically growing in diameter in response to the musical signal input to the magnets. (Did I mention the word ingenious...;-))
What is amazing is the area of these two cylinders is on the order of 50 to 100 times that of a standard 3/4 or 1" tweeter with comparable liner excursion!! Not a Ribbon, not a DD, not anything similar.
FWIW I sold my Rockport Cygnus and bought the Courantes after hearing the bigger Counterpoints at AXPONA.
FINALLY I have uploaded an animation that Zoltan shared with me recently visually describing the BRS for those who are interested.
Here's the link showing the BRS 2.0 diaphragm configuration and movement
