ViaWave SRT-7

Ribbon tweeter with SRT membrane, flat flange 104 mm diameter, 8 ohm impedance

The SRT-7 tweeter is designed on the basis of the GRT-145-8 tweeter.
The design of the rear chamber of the SRT-7 is modified to obtain the smoothest frequency response in the operating range.
The SRT-7 uses a patented technology for sealing the air gap between the ribbon and the poles of the magnets.
Developed by Viawave Audio, this technology is called SRT - the sealed ribbon tweeter.
The gap is blocked by a U-shaped suspension made of heat-resistant polymer film.
SRT technology radically reduces the nonlinear distortion of the tweeter and allows it to operate at lower frequencies, while maintaining the transparency of the ribbon speakers sounding.
By combining SRT technology and a powerful magnetic system, a unique sensitivity was achieved for a ribbon of 7 cm2 - 95 dB/W/m in 4 - 18 kHz range.
The rear chamber of the tweeter is filled with a set of felt plates of a certain shape.
This way of filling the rear chamber provides a very high repeatability of the parameters of tweeters.
