Seas 27TDFC Tweeter, H1189-06 - Prestige Series

Seas 27TDFC Tweeter, H1189-06 - Prestige Series

27TDFC is a High Definition precoated fabric dome tweeter with a wide, soft polymer surround and a rear chamber. Sonotex precoated fabric diaphragm with high consistency and excellent stability against variations in air humidity Sonomax surround for low resonance and excellent mechanical linearity. Voice coil windings immersed in magnetic fluid increase short-term power handling capacity and reduce the compression at high power levels. A stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be used with moderately low crossover frequencies. The chassis is precision molded from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.
