Need help with Speaker Selection

[jb1013]

Hi thanks a lot for reading!

I'm working on designing a new 5.1 surround sound system, to go into a home that is currently being remodeled, so this is a pre-construction install.

The 42" flat panel display is going to be over the fireplace and the bottom of the display will be at around 60+" from the floor (I know its high, but this is not something I can work around). So basically I don't have room to install the center channel below the Display as it would just push it the display that much higher. So I think I would like the center channel to be either "In Wall" above the display or "In Ceiling". If its in wall its going to be very high, pretty close to the ceiling.

I'm thinking I'd like to use the lsi9's as the front channels that will reside in Built In bookshelves to either side of the Fireplace and Display

The subwoofer will be in the bottom cabinets of the Built In Bookshelfs. I'm thinking about one the DSW Pro Series, or maybe the PSW505. Anything I should be aware of for having the sub in cabinet? Anything I should make the cabinet builder aware of?

For the Rear Channel I was looking at the TC60i's, I will also be installing 10 more of these or whatever speaker I decide on in other zones throughout the house.

For the Center Channel I was thinking about either the LC80i mounted in the ceiling, or the LCi-C mounted in the wall.

What about timber matching from the lsi9 fronts, LC80i or LCi-C center along with the tc60i rears?

The 5.1 system will be powered by an Onkyo TX-NR905 A/V

Any recommendations, suggestions, advice would be greatly appreciated.

I'm no expert, but I can forsee a lot of rattling with a sub inside a cabinet like that. Also, the cabinets might play a role in sound quality as well.

I think this is a valid concern, for sure. That's why I'm looking for input regarding this. The cabinets are still be designed, so if there are steps I can take to minimize problems, I'd certainly like to hear them.

One thought is to have a circular cut in the bottom of the cabinet that would vent out the riser in the front. I can add either some kind of vent or speaker mesh to it.

I suppose one of the other options would be for me to go with one of the in wall subs.

I'm obviously new to these forums, does anyone from Polk tend to answer in these threads. I also sent an email to their support people asking these same questions, and never heard anything back.

I'm sure the home theatre folks will probably disagree, and I'm primarily a two channel guy, but I think a setup with Lsi9's in the front and Lsi7's for rear channel would sound great. Never understood why a center channel was needed if you have a soundstage like the Lsi series produces. A sub might be good and I doubt placement of the sub would be critical.

The rear channels need to be in ceiling, and the owner is wanting a full 5.1 surround system.
