I am building an new house and want to put surround sound in my family room with plasma screen over fireplace. My electrician uses the "Levitron Architectural Edition powered by JBL installed theater speaker and components". I have no experience with surround sound. He also uses Nutone ceiling speakers. Please give me any feedback on systems. I have to answer him quickly. He says its around $700. The room size is 14x24. Help please!
