Description
The R-A90S features a staggered power channel layout that allows each channel to host different levels of power, compared to traditional, multi-channel amplifiers. This allows the R-A90S to effectively function as both a 3-way active amplifier and a 5-channel amplifier by delivering the power you need to the channels where you need it the most.
Hear the subtle details you’ve been missing in your music with the R-A90S. With the highest power output in its category, the R-A90S drives power to your sound system to create a big dynamic music range for the listener, reproducing high-frequency sounds up to 45k Hz, making the R-A90S Hi-Res Audio Compliant.
Alpine’s R-Series line of speakers, subwoofers, and amplifiers have a heritage of sound quality that can be heard from a block away. The R-A90S is tuned to emphasize the characteristics of the R-Series speakers and subwoofers for a legendary R-Series experience.
