This has been covered extensively in this thread with many user reviews of 5.1/7/1 upmixed with Dolby Surround Upmixer (DSU). A search will help you come to a decision.

All I have said, IIRC, is that the Di5s are in line with Dolby specifications, which they are. The entire issue of their dispersion patterns was a result of an error in their documentation, which...

It is. But small rooms (like mine) and heavily treated rooms (like mine) can benefit from the 'Flat' setting. I have been running XT32 'Flat' for a while now and, in my room, it seems to add a little...

This debate has also raged for years with conventional 5.1 systems. It's no different now - it's just, as Scott says, the speakers are on the ceiling this time instead of on the floor (stands). Just...

You make good points. It's more of an 'academic' discussion I guess, rather than intended as practical advice. I agree with you - most speakers seem to work pretty well and I cite (again) Dolby's own...

I’d love to see where that is stated. At the Dolby 'typical home theater' demos the ceilings were all ~8ft (2.4m) and bipoles were definitely not used. So either the new information is not correct or...

Difficult to be 100% sure but my guess would be 'no'. But then, they are not specifying different speaker types for different elevations either.
