Hi Friend,
I searched for some atmos speakers last month and finally got a quote from Onkyo (through their facebook account) on their SKH-410 as MSRP 19.5k. The final quote from the dealer was 17k. These speakers can be used in an up-firing setup as well as can be wall mounted.
Finally for my atmos setup, I got normal Onkyo surround speakers and mounted on to the wall (near the ceiling) pointing to the listening position. Somewhere I read that this will not give the optimal immersive experience and it is always recommended to use ceiling mounted speakers.
But I am more than happy with the current setup, may be down the line I can upgrade to a ceiling mount (unlikely).
Till that day, I am very very happy with the current setup and experience :yahoo:.
