This product has been replaced by the Waveguide version: VIAWAVE GRT-145W-4 Speaker Driver Ribbon Tweeter.
Sealed ribbon tweeter 4 ohm
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.
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.
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.
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.
The front has multiple bindings that will facilitate the integration of complex speaker systems, leaving no room for error.
