The Acoustic Research AR-5 Tower Speakers are a pair of right and left speakers with an integrated powered subwoofer. The sleek black speakers have an audiophile sound. Perfect for a 2.0 channel home audio system, these wired speakers from Acoustic Research offer a high-quality listening experience with a modern design. Ideal for TV, video, and music lovers looking to enhance their home audio setup. When I first got these speakers they needed a few things. I wound up upgrading the surrounds, recapped the amps and a few other things. I have been blessed to evaluate many different speakers over the years. These AR5s are exceptional. They seem to do everything right. The 300 watt subwoofer produces as much bass as one could possibly hope for. Everyone I have let listen to these have all been impressed. Smooth, detailed non-fatiguing sound. I had intended on keeping these but circumstances are so that I need to sell them.
