Hi Rontalley and Sanjiv and others,
I went to dolby's site and this is their recommendation for 5.1.4
So two speakers in front of MLP and two at back. Since the MLP has a wall at the back, I was thinking the rear become mids.
Take a look at my room layout ...
Notice the following,
There is duct work on the right hand side of MLP. I had another look at the area tonight and think I can rework the duct work such that there is a 12' gap between the back wall and start of duct trunk. I could fit a ceiling speaker (ie TRR or TMR) here. As this is very close to the back wall, I am not sure if this is a good idea. I will then extend this duct all the way across the room (which will house a return). The TRL or TML speaker is situated on left hand side.
Both TR/M left and right are about 10 feet apart. The bad part is that they are very very close to the back wall.
There is another bulk head in this area sort of in middle of the room. I could put TFL and TFR in this bulk head, symmetrically opposite TR/M speakers on the back wall. The distance between TF and TR/M speakers is also 10ft.
What are your thoughts. I am thinking of using Kef Ci200QR here for their wide dispersion. But could also go with ceiling speakers with amiable tweeter such as Speakercraft Aim 7 series 2 and aim the speakers towards MLP. Both I can obtain for similar pricing.
A picture of the existing duct work in the pic below. I will have to rework some ducts to free up space between backwall and the start of the duct.
This is pic taken from standing at MLP and looking right. Notice, the existing duct. I will have to rework that duct to squeeze in the Ci200QR.
The ceiling speakers will be slightly more than 8ft from ground as they are installed in bulk heads. The normal ceiling height is 9ft.
Sanjiv, you had mentioned front height speakers on the front wall. This is an interesting idea aswell, but I don't see dolby recommending this in their 5.1.4 arrangement. I would likely have to buy something like Kef R100 instead of their inceiling speakers to angle the front height towards MLP. There is quiet a bit of pricing difference between a pair of R100 vs pair of Kef CiQ200QR.
Thanks for your insights. Again very much appreciate it.
