Monitor Audio Radius 90 (pair)

Regular price $629.00

High-performance sound from a tiny speaker

From the minute you unpacked the Monitor Audio Radius R90s, you will realize these speakers are downright beautiful, and almost impossibly small. The real surprise comes when you hear the open and spacious sound they delivered. 

Use them with a subwoofer for deep bass

If you're looking for big, powerful bass, you will definitely want to add a powered subwoofer. Use a pair of R90s in a 2.1-channel stereo system for room-filling sound. Or mount four or more around your home theater room for surround sound with superb detail and clear dialogue.

Monitor Audio's superlative Engineering at an affordable price  

Both its 4" woofer cone and 1" dome tweeter are made of a high-tech ceramic-coated aluminum/magnesium alloy. This exceptionally stiff, lightweight material allows the drivers to respond swiftly and precisely to the audio signal for greater accuracy. The tweeter also gets an anodized coating of gold that helps ensure smooth, extended highs.
