Seas loudspeaker H0561 8 OHM 19TAF/D, tweeter 19mm High Fidelity dome tweeter with smooth, extended frequency response. Aluminium diaphragm suspended by a specially designed soft Sonotex surround which allows a low fundamental frequency. Injection moulded chassis in high grade glass fibre reinforced plastic keeps the moving parts in perfect alignment and provides good coupling to the cabinet. Carefully designed diffuser protects the diaphragm and compensates for a slight axial roll off towards 20 kHz. Voice coil windings immersed in magnetic fluid increase short term power handling capacity and reduce the compression at high power levels.
