Viawave Audio GRT-145-4

Sealed ribbon tweeter 4 ohm

Tweeter ribbon GRT145-4 Viawave
A pair of ribbon tweeters with excellent frequency response and very good sensitivity while maintaining the distortion under a very low threshold. These parts are designed and hand-assembled with great attention to detail.

SRT

Tweeter Frequency Response GRT-145-4

Senior GRT-145-4 speakers exploit the SRT technology (sealed ribbon tweeter). This technology developed by Audio Viawave consists of placing a polymer film between the tape and the poles of the magnet. This type of construction greatly limits the harmonic distortion, especially in the lower frequencies that cover this type of tweeter.

One feature that refines the sound precision while specifying sensitivity. Indeed, it is considered that the SRT technology increases the final sensitivity of 2 to 3dB.

Excellent management magnetic stresses

Cumulative spectral period of tweeter speakers

With a magnetic system built with precision, the speakers feature tweeters TSO 145-4 remarkable sensitivity to this class of equipment. On a range of 4 to 18 kHz, it manages to achieve a sensitivity of 95dB / m @ 2.83V, a tour de force for a ribbon tweeter 7cm². It may therefore put some its great sound precision midrange service to enjoy a brilliant and clear.

Similarly, its top desgin allows it to provide a clean, clear sound over the entire response range. These speakers show indeed a cumulative spectral period such as can be found in the professional equipment.

Type of mounting

The tweeter format allows him to enjoy all the depth of a speaker enclosure to avoid sacrificing floor space while providing an aesthetically uniform result - even with massive loudspeakers serious.

rear dimensions and connectors 145 GRT

The rear connections are thought to increase the mechanical stability while remaining easy to install and connect to other elements. In addition, this construction allows to easily configure filters and crossover essential to make the most of this tweeter.

Many fasteners and easy installation

The front has multiple bindings that will facilitate the integration of complex speaker systems, leaving no room for error.
