  • Kevlar low-frequency driver gives consistent dispersion across the frequency range
  • Designed for commercial, home, broadcast and post-production studios

Purpose-built 8" AMT monitor

The Presonus R80 AMT is an active studio monitor designed for commercial and home recording studios as well as broadcast and post-production environments. It uses a custom 6.8-square inch Air Motion Transformer tweeter that responds to the subtlest waveforms and highest frequencies. A 150W Class D amplifier powers the unit for an open, clear and less fatiguing listening experience.

Limits of AMT tweeter design

The folded Kapton membrane provides 8 to 13 times the projection area of a traditional 1-inch dome tweeter, yielding a much wider stereo soundstage. Superior transient response time captures fine detail, though the specialised driver topology is optimised for critical near-field accuracy rather than high-SPL main monitoring. The custom-coated woven Kevlar low-frequency driver supports consistent dispersion across the frequency response range.

Deciding spec: 150W Class D power

The 150W Class D amplifier defines the headroom and dynamic capability available for mixing and mastering tasks. Buyers needing higher output levels for larger control rooms or main monitoring positions should evaluate whether this power rating meets their SPL requirements. The single-unit configuration also means stereo pairs must be purchased separately for standard monitoring setups.

Questions about this item

Should I pick the 80 W or 150 W version of the R80 AMT?

The R80 AMT uses a single 150 W Class D amplifier to drive both the AMT tweeter and the 8-inch woven Kevlar woofer, so there is no separate 80 W model to choose between.

What does the 150 W Class D rating mean when the monitor is in my studio?

It means the built-in amplifier can deliver 150 watts of continuous power to the custom AMT tweeter and Kevlar low-frequency driver, providing high output with low distortion for accurate mixing.

What interface does the 6.8 sq in AMT tweeter use and what does that cap in practice?

The Air Motion Transformer tweeter is driven directly by the internal 150 W Class D amplifier, so its output is capped by the amplifier's power and the tweeter's own thermal limits rather than any external interface.
