JBL Professional Control HST - speaker

The dual tweeters feature aluminum diaphragms with a CMMD treat, polyurethane surround, a neodymium magnet, and fluid-cooling for high output, low distortion and humidity resistance.

The well-damped woofer incorporates a CMMD ceramic metal matrix diaphragm for a very high stiffness-to-weight ratio, high output, resistance to humidity and long-term durability.

Engineered noise canceling allows Control HST to provide a flatter resulting frequency response along with a more consistent sound character throughout the room.
