The other thread gave me this idea. We have been through three different receivers and blown out speakers. One of the receivers looks to have fried during a lightning storm. Today, while the volume was up, it tripped the breaker and seems to have fried the receiver. We need to push out sound at a decent level that can fill up 5000sq ft with 20ft ceilings. Sound quality doesn't have to be ridiculous. Where the heck can I find something that would fit the bill? It's all boom boxes from the 80s or 90s, home theater systems, or DJ equipment. Craigslist isn't being fruitful and I can't find where or what to buy new.
