The PreSonus R series studio monitors offer user-adjustable contour features for optimizing the monitors for your mixing space. This enables full integration into any studio environment. A four-position Acoustic Space switch helps to compensate for the boundary bass boost that occurs when the monitor is placed near a wall. A high-frequency driver level control helps to further mitigate room anomalies, and an onboard highpass filter makes it easy to integrate a Temblor subwoofer into your monitor setup. The R series’ highly accurate, transparent sound makes them ideal for use in both commercial and home recording studios as well as broadcast and post-production environments. Bi-amped and driven by a 150W Class D amplifier, the R series has some of the most powerful monitors in their category, delivering an open, clear, and less fatiguing listening experience.

Clean Stereo Image

The R80 features a custom 6.8-inch Air Motion Transformer (AMT) tweeter that responds to the subtlest waveforms and the highest frequencies, allowing you to hear the “air” and the greater sense of space that is characteristic of audiophile recordings. Unlike a traditional 1-inch dome tweeter, which provides a mere 506 mm (squared) projection area, an unfolded AMT tweeter diaphragm provides 8 to 13 times the projection area so its sound coverage is much larger. For example, the 4,400 mm (squared) PreSonus 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 soundstage than traditional designs.

The R80 also utilizes 8-inch, custom-coated, woven Kevlar® low-frequency drivers. This rigid cone maintains a more consistent dispersion pattern across its frequency response range, giving a wide lateral dispersion and a 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, and because they are less subject to room-anomaly interference, the R65 reacts more predictably and consistently from room to room.

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 R80 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. With three different types of audio inputs, it’s easy to feed audio to your R-Series monitors from a mixer, an interface, a media player, or almost any other line-level source.

The R80 provides balanced XLR, balanced ¼” TRS, and unbalanced RCA line-level inputs. The responsive nature of the R80 AMT monitor design provides lifelike sonic reproduction that will allow you to hear the room and breath in your recordings. The transparent sound and responsive transient reproduction make them an ideal solution for anyone who is mixing high-resolution audio.
