Black Aluminium Cone Mid/Bass
The 23W 4557T02 produces a clean, dynamic natural sound with low distortion and a good transient response.
The ultra long throw voice coil uses aluminium wire wound onto a paper reinforced Kapton former along with Scanspeak's patent diecast aluminium chassis, allows the 23W to produce a bass response of unusual depth and precision.
