Tweeters à compression Beyma CP21F
[CP21F-8] Avis/Critiques Points forts :
1.5" (37.6 mm) edgewound aluminium ribbon voice coil
Great power handling: 25 w AES
High Sensitivity: 105 dB
Very similar model to the CP22 but with wider
horizontal dispersion (140º)
Designed for applications with need of wide horizontal dispersion and precise high frequency coverage.
Description :
This compression tweeter is designed for use in multi-element loudspeaker systems in both sound reinforcement and studio applications. It features smooth response with wide controlled dispersion in the horizontal plane (140°). The voice coil is wound from flat aluminium wire, bonded to an aluminium diaphragm for extended response and excellent transient attack. The diaphragm assembly is field replaceable without soldering.
