Reviews

Anthem MRX 300 review

It provides a room filling sound without cranking the volume too high, but when pushed it flat out refuses to distort. Bass is of the highest order too, making every gunshot or explosion punch right into your gut. ARC deserves a special mention here. After room correction, the sound is tighter and more focused, with less bass boom from the subwoofer that stops it overpowering the other speakers.

Anthem MRX 300 A/V Receiver

The Anthem MRX 300 is the first A/V receiver to bring Anthem Room Correction below the psychologically potent $1,000 price point. It would be noteworthy for that alone. But there’s more. The AnthemLogic-Music mode is remarkably fine and may be especially well suited for systems whose center speakers are less than perfectly timbrematched. Dolby Volume is a superb addition for any system that you’ll use for movies. Altogether, this is a very impressive AVR and a must-hear.
