I'm starting construction of a room addition and for all the reasons most everyone here will understand, I need to install in-ceiling speakers for the AV system. The fronts are an easy choice - put the Invisa HTR7000's in L/C/R - but the rear/surrounds are where I'm looking for the collective wisdom of the group and the moderator to provide some suggestions. For similar aesthetic and budget reasons I'm not planing on putting in 4+ more speakers in the rear to try to get to 9.x.x or 11.x.x so that means I can put two in-ceiling speakers in the back of the room. The thought was to use the MPX as a way to create a more dynamic stage for movies which is the primary purpose of the av in this room. That said, my questions come down to 1) Pros/cons of using the MPX vs. running 5.x.x and just putting in two more HTR 7000's for the rear? 2) If I run MPX, should I wire them separately as different channels to jump from 5.x.x to 7.x.x? 3) Placement and orientation - depending on the answers to the above, what's the reco on placement and orientation? See my hand-drawn layout below. There are of course architectural drawings for the room add, but this is a quick way to draw up what I'm getting at. Thanks in advance!

Update - I'm including a link to the drawing as I'm unable to upload the drawing (I receive a "failed to create attachment directory" notification upon uploading. Link to drawing is here.

Hi, Mattboyd33

Just some thoughts.

You quote possible 5 or 7.x.x systems someday. Are you thinking you may want to add height channels someday (the last .x)? Your sketch doesn't describe distances, but if so, and if you have the room to keep the HTR 7000's far enough away from the listening position to project at ear height, then I'd lean towards going with 7000's for the surrounds also so that you have ear level sound all around and preserve any future option to add height channels.

What are you planning on for bass support since none of the speakers you mention are really designed to be full range speakers? A sub would add the dynamic sound you are thinking of using MPX's for also.

Have fun with your project!

Hopefully reading this correctly... HTR-7000 or MPX for surround in the ceiling?

The 7000 as surrounds will work great if you can place them far enough to give good focus. If not, MPX in the ceiling will work well.
