PreSonus R80 active studio monitors are fitted with a custom 6.8" Air Motion Transformer ribbon tweeter that delivers superb transient response and ultra-low distortion. The R80's custom-coated 8" woven Kevlar LF driver provides more dynamic output than conventional woofer designs, thanks in part to the rigid cone's superior ability to maintain a more constant dispersion pattern across its frequency response range. Amplified by 100-watt RMS of Class D amplification driving the woofer and 50-watt RMS driving the tweeter, the R80 gives you exceptionally transparent sound with reduced reflections.
Superior clarity and transient response
To achieve high-frequency resonance-peak damping, many manufacturers inject conventional dome tweeters with fluid that raises mass, and in the process, sacrifice transient response time. The custom AMT tweeter in the PreSonus R80 uses an ultra-thin, folded Kapton membrane with an inlaid aluminum circuit that functions as the voice coil; this lets the tweeter move concurrently with the electric current. The result is most impressive clarity and superior transient reproduction that will make marathon sessions less fatiguing and give you better mixes.
Excellent dispersion and stereo imaging
As compared with traditional 1" dome tweeters, which provide a small projection area, an unfolded AMT tweeter diaphragm delivers between eight and 13 times the projection area - considerably larger coverage. This means you'll enjoy a much wider stereo soundstage with the PreSonus R80 than traditional designs can provide. The R80 exhibits wide lateral dispersion and very limited vertical dispersion. Narrow vertical dispersion reduces reflections from your ceiling and work surface that can cause smearing due to phase incoherence. The R80's broad, even horizontal, dispersion gives you a wide sweet spot. And being less sensitive to room-aberration interference, R80s perform more predictably and sound more consistent from room to room.
