Hear the most subtle details.

The R65 features a custom 6.8-square-inch Air Motion Transformer (AMT) tweeter that responds to the subtlest waveforms and the highest frequencies. This allows you to hear the “air” and the greater sense of space that is characteristic of audiophile recordings. The R65’s transparent and highly accurate sound makes it ideal for use in both commercial and home recording studios as well as broadcast and post-production environments.

Superior transient response.

In order to dampen resonance peaks at higher frequencies, conventional dome tweeters are injected with fluid to raise their mass, sacrificing transient response time. By contrast, the custom-designed AMT tweeter in the R65 uses an incredibly thin, folded Kapton^® membrane (< 0.01 mm) with an inlayed aluminum circuit functioning as the voice coil, allowing the tweeter to move at the same instant as the electric current. The resulting reactive response time provides marked clarity and superior transient reproduction.

Features

Components and Construction

2-way active AMT design provides articulate high-frequency response and wide stereo imaging
Custom-designed, 6.8-inch, AMT ribbon tweeter responds to the subtlest waveforms and the highest frequencies
6.5 woven composite LF drivers provide transparent mid- and low-frequency reproduction for clean sound and punchy bass
Balanced XLR and ¼-inch TRS plus unbalanced RCA inputs provide flexibility for seamless integration into any environment

User Controls

Acoustic Space settings (Linear, -1.5 dB, -3 dB, -6 dB) compensate for room placement

Wide, consistent stereo image.

An unfolded AMT tweeter diaphragm provides 8 to 13 times the projection area of a traditional 1-inch dome tweeter, enabling R65 monitors to provide a much wider stereo soundstage than traditional designs. At the same time, the R65 provides a very limited vertical dispersion, which helps to reduce reflections from the ceiling and desktop that can cause phase coherence issues. Because it’s less subject to room-anomaly interference, the R65 reacts predictably and sounds consistent from room to room.

Transparent sound.

The R65 utilizes a 6.5-inch, woven composite, low-frequency driver. This rigid cone maintains a more consistent dispersion pattern across its frequency response range. Biamped and driven by a 150W Class D amplifier—making the R series some of the most powerful monitors in their category—these monitors deliver an open, clear, and less fatiguing listening experience.
