hy, i am currently building a new house and i have put wires in the walls for speakers. i have a main room that is about 500 square feet and wanted to put in 4 speakers in the corners, and 2 outside on the deck. this is a beach house so i am worried about salt water air outside but the AC will be running 24/7 inside. my budget is about 700$ for 6 speakers and they will be used primary for listening to music and not videos. what speakers do you guys recommend, i have been looking at the yamahas or the polks that show up in the amazon listing and dont really know about the out door ones yet.
