SEAS H0881-06 (27TFFC) is a High Fidelity precoated fabric dome tweeter with an integral wide surround and a rear chamber.
Sonolex precoated lightweight fabric diaphragm with high consistency and excellent stability against variations in air humidity.
Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels.
Stiff and stable rear chamber with optimal acoustic damping allows the tweeter to be used with moderately low crossover frequencies.
The chassis is precision moulded from glass fibre reinforced plastic, and its front design offers optimum radiation conditions.Specifications
