Viawave GRT145


Introducing our new product, the GRT145 sealed ribbon tweeter

Viawave Audio proudly introduces a true world first in the GRT145; the technology of 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.

In the SRT, the gap between the ribbon and the magnets is covered with a U-shaped mylar suspension. This dramatically reduces harmonic distortions at low frequencies of the operating range whilst also increasing the sensitivity by 2-3 dB.

By combining our 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. In a tweeter with a 4-Ohm resistor it corresponds to 98 dB/m at 2,83 V.
