Vifa H26TG-45-06 6Ω silk dome tweeter, high output.
This high efficiency tweeter features a Neodymium magnet assembly, 25mm damped silk dome and a ferrofluid cooled voicecoil. The H26TG-45-06 has a horn loaded faceplate (104mm diameter) with recessed mounting holes - the horn loading yields a high efficiency of 94.6 dB/ 1W / 1M, making this tweeter ideal for use with low powered amplification.
H26TG-35-06 and H26TG-45-06 are the same - either may be supplied.
