Questions for HT with Forte IV and PRO-180RPC LCR

[IvanLionel]

Hello, I'm planning for building a system for both home theater and music. To have better sound for music without influencing the home decor too much, here is my current plan for a 5.1.2 system:

 

Left and Right: Klipsch Forte IV

Center: PRO-180RPC LCR

Rears: Not selected yet

Atmos: Not selected yet

Subwoofer: Not selected yet

AVR: Marantz SR7015

 

And here are the questions I want to get your opinions:

1. I know PRO-180RPC LCR should be paired together as LCR, just wondering if anyone knows would it perform well with Forte IV? Since the L&R would be floor standing, would PRO-180RPC LCR sounds weird since it's in the ceiling?

2. For the rear speakers, I used to think about Pro-180RPC LCR as well. But I'm not sure if 45 degrees would be too much for my space? Would Klipsch CDT-5800-C or regular PRO-180RPC perform better?

3. For the Atmos, it's kind of similar, the 45 degrees may be too much for the atmos speakers, would Klipsch CDT-5800-C or regular PRO-180RPC perform better?

4. As for the sub, I'm thinking about GoldenEar SuperSub X, but if the in-wall or in-ceiling speaker like PRO-1000SW or PRO-800SW could perform similarly, I may prefer the in-wall or in-ceiling solution. Any suggestions?

5. For the AVR, I think all the speakers I'm looking at have high sensitivity, I think SR 7015 would definitely be enough for HT. But for the music, would it be worth having an amp for the Forte IV to get better sound? or just upgrade the AVR to Denon 6700h?

 

I really appreciate your help in advance!

I also attached my floor plan with the location of speakers I'm thinking now.

 

EDIT
Thanks for all the feedback! I would forget the in-ceiling center and rears. I would appreciate it if anyone can give me suggestions on:
1. Any recommendations on the center and rear speakers which would well pair with the Fortes?
2. If this is the case, would it be worth it for me to upgrade to a 5.1.4 system?
3. For the sub, would the in-ceiling or in-wall sub perform well?
