Review Summary

Rated 4 out of 5

Ceiling mounted for Atmos

I held off for a while on an Atmos setup. I finally gave in and chose the DI 8R (2 pair) after reading recommendations on a forum. Installation is very easy. Sound quality is very good for surround (Atmos) setup. Power handling is great (separate power amp each pair). They also do an excellent job using DTS-X and Auro 3D modes blending very well with my speakers; ST-L, Mythos Ten, Mythos Gem XL (F Height, Side and Rear).
