Seas 22TAF/G H1283-06 is a High Definition metal dome tweeter with wide, coated fabric surround and combine the high frequency behaviour of a ¾” dome with the low frequency characteristics of a 1” dome.
Aluminium/magnesium dome for low mass and high rigidity and stability. Protected by an acoustically open Hexagrid. Precoated Sonomex surround gives low resonance frequency, 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. The chassis is moulded from a stiff and stable glass fibre reinforced polymer material, and its front design offers optimum radiation conditions. Large ferrite magnet gives high efficiency.
