Tweeter à ruban haut de gamme caractérisé par une courbe de réponse très linéaire, une vitesse et une précision dans les transitoires. Le RT8II a une capacité extraordinaire à reproduire les instruments à spectre de fréquence complexe. Contrairement à la majorité des tweeters conventionnels ou électrostatiques, le RT8II possède un champs de dispersion horizontal extremement large. A recommander sans réserve.

Tweeter Hi-Fi à ruban Hi-Vi Research RT8II
Contrary to a conventional electro dynamic driver, this transducer has a driving force distributed evenly over the whole area of the vibrating element.
The key element of the RT8ii is the membrane, which consists of Kapton? Film with a pattern of Aluminum conductors. The conductors cover about 90% of the whole vibrating area. The membrane assembly is precisely placed between two rows of 36-way Neodymium bar magnets. This tweeter is magnetically shielded and is an extremely flat driver.
It has resistive impedance in the audio frequency range. This unique feature provides a friendly load for any amplifier and facilitates easy crossover design. It has an essentially linear phase response that provides time coherent reproduction resulting in accurate musical rhythm and imaging. The vibrating element of the RT8ii is almost weightless to that of a dome tweeter. As a result it provides an immediate and precise response to any transients in the original signal. RT1 has an exceptional ability to reveal the dynamics of instruments with complex high frequency spectra.
Unlike conventional tweeters and electrostatic speakers, the RT8ii has an extremely wide sound dispersion in the horizontal plane.
Contrary to other dynamic tweeters, the RT8ii has well-controlled dispersion in the vertical plane. This feature helps to avoid disturbing floor and ceiling reflections, increasing imaging accuracy. With this tweeter, there is no need to manipulate the network or use multiple units to achieve the restricted vertical directivity necessary for home theater applications.
RT8ii possesses unsurpassed clarity, transparency, and the ability to deliver every tiniest musical detail. Since RT8ii has exceptional ability to reveal the dynamics of instruments and sonic resolution, it is recommended to match it with drivers having similar properties in order to maximize the overall integrity of a speaker system.
