Building a home theater system and need some advise. My room size is approx. 15 feet wide, 22 feet long with a 10 foot ceiling. I don’t have any experience with this but I have spent a lot of time reading and viewing posts. I live in Costa Rica and don’t have HD and wont have in the near future. This is what I have come up with and would like some advise on my choices. Panasonic PT-AE900U Front Projector / screen size 102” – 120” Yamaha HTR-5890 7.1 or RXV1500 7.1 Receiver Yamaha DVC-6760 5 disc changer / All Zones All units approx. $2200 Would like some recommendations on a 5.1 speaker system to go with the Yamaha Receiver. Would like to keep the speaker price under $500 if possible. Thank you for your time and advise. CRBookie
