\rHi Richard:
The ideal matching in-ceiling speaker for surround and effects (ATMOS/DTS:X) is our ACE670 6.5" Angled Trim-less speaker featuring the same Metal dome tweeter and Carbon Fiber Cone. The angled speaker allows you more flexibility for placement. The ultimate goal is to have every speaker's Tweeter aimed towards the optimum listening/viewing location.
