R-Series R-A75M Mono Power Density Amplifier


The new R-Series amplifiers produce accurate imaging and dependable power. Use them with the R-Series speakers and amplifiers for a loud and fun experience.



R-Series amplifiers have a built-in bandpass filter which lets you design an active speaker set-up without a separate processor. Improve the sound quality of component speakers by ditching your passive network.  Avoid added phase shifts and power losses by individually powering each component and assigning your own frequency bands for the incredible sound you’re looking for.
