Just though I would share a little story about my new wires... So I've been a part time projectionist at a family run 10 plex movie theater for the past 8 years. Recently the owner passed away and his wife sold it to a small local theater chain. They decided to do a complete renovation to it and started in August and are just finishing up now. I don't think much of the new owners and the way they go about business and planning for this renovation but one of their project planning mistakes became my benefit.
They overordered speaker wire by buying about 5x too much and most of it was not in wall rated so the installers refused to use what they bought except for inside the equipment racks. They had 5 spools of 300 ft 12 awg monoprice wire and 8 spools of 100ft 10 awg dayton audio wire. From going through their emails, I gathered that someone was supposed to return it but the message was miscommunicated....
Anyhow, I swipped a spool of the 10 awg dayton stuff because it was thicker gauge. I then looked up the price on parts express where they got it from and saw it costs about $110 (like I said poor business mistakes from lack of planning... that was a costly mistake). I rewired all my speakers the other day with it and can say it definitely made an improvement. The surrounds are more active and have noticeable subtle effects I didn't hear before. The fronts really opened up with more depth and detail than before.
The wire I was using before this was also wire I took from my theater years before. It was 12 awg inwall stuff with no brand name on it. It was just on a large bulk wooden spool if found under one of the screens. The wire I was using before for the surrounds was 18 awg radioshack brand because I didn't have long enough runs of the theater stuff. I just wanted to share my experience between different wires. I don't know if going from 12 to 10 awg was what made the difference or if it was the strand count (the old stuff was pretty stiff and had less but thicker strands) but I am really happy with my new free product.
