Description
The Anthem MRX-SLM is a slimline AV receiver designed for discreet, high-performance home cinema setups where space is at a premium. Despite its ultra-slim profile, it delivers powerful 5.1 channel surround sound and cutting-edge features, making it ideal for living rooms, media rooms, or compact home theatre environments.
Built with Anthem’s renowned ARC Genesis Room Correction technology and Dolby Atmos/DTS:X support, this unit brings immersive sound precision to any installation.

It suits design-conscious homeowners and custom installers seeking uncompromised AV quality in tight quarters.
