[Guesses on Klipsch's "Biggest Launch in Years" at CES on 01-06-15]

Not to be a Debbie Downer, but I guess the facts that the new Reference Premiere bookshelf speakers are rear-ported, lack wall-mounting hardware, and have a (presumably) non-removable plinth base rules them out for use as wall-mounted surrounds, huh?  I prefer the WDST surrounds myself, but those particular RP bookshelf design choices might alienate that segment of folks who prefer to use monopole speakers for surrounds.

 

And what's the thinking behind the slight upward angle the bookshelves seem to have?

The RP-150M have wall mount hardware on them.

Did you ever figure this out? I am looking at getting the Reference S4i and have a 4S.
