Inconspicuous HRV/ERV ceiling inlets/outlets

What's everyone using for small diameter (3", 4") ceiling duct terminations, such as what might be used for a HRV or ERV? Can't find anything that would be low profile and require a minimal cutout...

diffusers
I've seem everything from conventional louver-type diffusers to the round outlets for hi-velocity systems used. The only thing I would recommend is that the outlets be mounted so they don't discharge directly onto anyone. ER/HRV units are only about 80% efficient, and can discharge cold air on days when it is very cold outside. Insulation of the ductwork is vital.0 -
Thanks!
The diffusers seem to run on the large side of things. I like the high velocity outlets but they're $pendy. Oh, well...0
