This silk, soft dome tweeter is perfect for anyone looking for smooth high end frequencies in a rugged frame. The transducer technology supplies clear, crisp, and consistent performance, using a custom-built, thin silk membrane to deliver a flat frequency response. It's wide bandwidth and high sensitivity make this tweeter ideal for multi-way systems looking to reproduce the finest overtones and harmonics.

  • Black 4" Aluminum Face Plate
  • Custom Design, 25 mm Silk Dome
  • Light Weight CCA Voice Coil Wound on a Polyimide Form 
  • Ferrofluid Cooled and Damped
  • Flat Frequency Response

Note: Protect the tweeters that are installed in your audio system. Lower frequencies are not desirable signals to send to a tweeter. They can damage or destroy the tweeter diaphragm. Protection is important. Use a simple passive crossover (First Order), by using a (proper value) capacitor to stop low frequencies from making it to the tweeter. You can also further refine your audio system by adding more complex crossovers with inductors and more capacitors and resistors. Or, ultimately you may want to add an active crossover system.

MISCO engineers test and analyze the performance of these speakers using the world's most sophisticated loudspeaker measurement systems including the Klippel Analyzer and the Klippel QC, which confirm the final design.
