“Free swinging tweeter” is a true-ribbon tweeter used throughout VMPS line. It is one of the best tweeters available today. It’s advantages over previous spiral ribbon tweeters were easily audible and cost is not overly prohibitive.
We use custom version (8 Ohm, custom transformer and diaphragm) of similarly looking Aurum Cantus tweeter. The FST tweeter has 30 degrees of vertical dispersion, less than 25 mm dome tweeter, but does not become directional at 11 kHz like a 25 mm dome. Horizontal dispersion is broad and even up to 25 kHz.
Foam pads surround the opening of the diaphragm, slot-loading the tweeters for better horizontal disperson.
