Commentary
This top-of-the-line speaker system uses a passive radiator system.
A 33 cm cone woofer and a 33 cm cone passive radiator ABR are used for the low band.
The ABR operates with a woofer due to pressure changes in the enclosure caused by vibrations of the woofer.
The mid-range has a 5.2 cm domed scoker, and the high-range has a 1.9 cm domed tweeter.
