Oh, thanks. I would like to understand internal layout of the ring diaphragm, rear chamber, compression chamber and the first horn section that goes from the diaphragm to the exit of the motor. It seems that the new BMS ring radiators don't use the same layout as the classic inverted dome compression drivers.
Thank you very much. I think that patent drawings solved my doubts, I was not sure about wehter the cavity had a 180 degree fold in the beginning or not. The dual diaphragm version got me quite impressed too.
They solved the old problem of lack of repatability in compression chamber size, usually resulting in different response in the top octave and bad stereo imaging by including the chamber in the diaphragm assembly.
Hey Rialb, are you alive?
