The SEAS T29B001 E0058-06B is an ultra high performance 29mm dome tweeter, featuring high sensitivity and a smooth, extended frequency response.
The dome is made from high purity Beryllium and manufactured to SEAS specifications by Truextent® in the USA. Being extremely stiff and lightweight, this precision dome ensures excellent performance and consistency.
The newly designed magnet system employs a high effi ciency Neodymium ring magnet, combined with shorting rings, to reduce non-linear and modulation distortion. A well-damped vented pole and a rigid rear chamber ensure a low resonance frequency and smooth response.
The 1.5 mm voice coil uses flexible lead-out wires and venting holes in the aluminium coil former, reducing noise to a minimum.
A 7 mm thick precision die-cast aluminium front plate with moderate horn loading ensures linear frequency response and represents an extremely stable platform for the magnet system and the moving parts.
