Description
The 93021 is a silk dome tweeter made for indoor systems, providing both high output, and smooth, low-distortion sound. A low resonant frequency design makes this tweeter easy to pair with high-quality woofers as well. Use this product to create top-notch line arrays within close-fitting spaces.
- Tweeter
- 1” (25 mm) basket diameter
- 20 watts, 4 ohms, 90 dB SPL
- High energy neodymium magnet
- Silk dome
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.
