I'm still learning the site, so bear with me. I built a set of cabinets to house full range Audio Nirvana 12" drivers awhile back. Was looking to make them and then sell them. Man, I just can't do it. It happens sometimes that you stumble onto something that is just you, and why would you give that up? It was a relatively easy bass reflex build, and when the drivers first arrived, I thought that I had just wasted $300 US on drivers. As many of you have experienced, the drivers broke in, and changed quite dramatically with a few hours time. Well crap, can't load my files at this time, sorry.
