Presonus R65 Studio Monitor Speaker


SKU: Presonus R65 Studio Monitor Speaker Categories: , , Tag:



The Presonus R65 Studio Monitor Speaker R65 feature a custom 6.8-inch2 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 Presonus R series’ transparent and highly accurate sound makes them 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 in-layed 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.

Clean Stereo Image as a pair

Unlike a traditional 1-inch dome tweeter, which provides a mere 506 mm2 projection area, an unfolded AMT tweeter diaphragm of the Presonus R65 Studio Monitor Speaker, provide 8 to 13 times the projection area so its sound coverage is much larger. For example, the 4,400 mm2 PreSonus R65 and R80 tweeter provides coverage equivalent to that of a 3-inch dome tweeter. This enables the R-series monitors to provide a much wide stereo sound-stage than traditional designs.

Consistent Performance

The Presonus R65 provide a wide lateral dispersion and very limited vertical dispersion. The narrow vertical dispersion helps to reduce reflections from the ceiling and desktop that can cause phase coherence issues. The broad, even horizontal dispersion creates a wide sweet spot. Because The Presonus R65 Studio Monitor Speaker is less subject to room-anomaly interference, the R65 reacts more predictably and sound more consistent from room to room.
