Presonus R65 - ACTIVE 2-WAY STUDIO MONITOR 6.5 "/6.8" 150W

(This text is machine translated) In the domes of conventional tweeters, given the need to attenuate the resonance peaks on high frequencies, fluid material is introduced to increase their mass. Doing so, however, results in a worsening of the response time to transients. The AMT tweeter specially designed for Presonus' R series, on the other hand, uses an incredibly thin (less than 0.01mm) Kapton-coated membrane, with a built-in aluminum circuit that acts as a voice coil. In this way the tweeter moves instantaneously to the passage of current and, thanks to this reactivity, the resulting response time guarantees high transparency and superior quality in the reproduction of transients. The diaphragm of an AMT tweeter guarantees a diffusion area of ​​8 to 13 times larger than a classic 1-inch dome tweeter, allowing the R series to obtain a much wider stereo panorama than a traditional system.
