I am looking to install wall mounted speakers in my sun room, which is roughly a 300 sq. ft. rectangle. It's glassed in and insulated, but I do plan to heat or cool it at all. Therefore, it will not get any rain or sunlight, but will likely have temperature fluctuations throughout the year (I live in central VA, winter nights as low as 10 degrees, summer days at 100), though the insulation will reduce the extremes a bit.
I was imagining two speakers mounted up near the top of an 8' wall at opposite corners of the long side of the rectangle adjoining the house, facing two walls of windows. First, does that placement make sense? Secondly, do I need outdoor speakers to handle the temperature changes or would indoor speaker work in this situation? Finally, any recommendations? My budget is about $5-700 for a pair.
Thanks for any guidance.
