New from SB! Beryllium dome at an affordable price. Many high-end features including optimized rear chamber and vented pole piece. High output above 92 dB. Strong response well above 20kHz.
Beryllium is incredibly rigid (seven times more rigid than Titanium or Aluminum) and is considered one of the best materials in the world for tweeter domes.
Extended frequency response past 20 kHz provides exceptional airiness and spatial quality with superb transients and micro-instrumentation. The result is a subtle, detailed, dynamic tweeter with fast response but without the typical harshness of metal domes that can cause listener fatigue.
With low resonance, very high output, excellent power handling and protective grille, this tweeter will work equally well for home hi-fi use or for high-end autosound applications.
Beryllium dome for non-resonant high frequency extension
Large surround dome for increased acoustic output
Copper cap for reduced voice coil inductance and minimum phase shift
Saturation controlled motor system for low distortion
Dual balanced compression chambers for improved dynamics
Flow optimized vented pole piece for optimum coupling to rear chamber
Non-reflective rear chamber with optimized damping for improved dynamics
CCAW voice coil for low moving mass
Long life flexible lead wires
Cast aluminium faceplate
Low resonance frequency
