Help with room treatments

Years back I built a ton of bass traps and misc. panels to try to fix the bass response in my basement.  I built 27 cylinder bass traps and quite a few panels as well.  If I walked into my basement listening room and just sat there for a few minutes my ears would start bothering me.  It felt like tiny muscle cramps.  I guess my brain didn't know what to do about the complete dead silence.  We're used to ambient noise and it's a strange experience to be without it.  

It was too dead in there and I tend to think poured concrete basements are a bad place for audio but I definitely learned something by getting it so quiet.  I also bought the behringer measurement mic and real time analyzer.  I had the bass trapped and equalized to +-1 db.  The process taught me that frequency response isn't everything.  

I do think that the best way to decide how much absorption you need is to start out with way too much.  Start out with a completely dead room and take absorption out until you start to hear the sound of the room and keep taking absorption out until you hear as much of the room as you want.  I expect beyond that is to bring in dispersion.  I tried a little bit of that but not a lot.  

Speaking of the homemade bass traps, I have about 15 of them that I'd love to give away.  They make a huge difference in a room.  They're the Risch style fiberglass insulation, wire fence, high loft polyfill and burlap.  If anybody wants to experiment this is a chance to do it for next to nothing.  The hard part is that they're bulky and you'd need to pick them up here in a northern Chicago suburb.  Some of them look fine, a few are a little rough.  They could be easily recovered or just stacked and then covered with a blanket or something.  There are a lot of ways they could be dressed up to look how you want them. 

They are all cylinders, not all exactly the same size.  There's a uHaul about 2 miles from here.  You could rent a 10 foot truck for $20 plus mileage to take them home in. 

I spent a lot of time and a few grand building these 10-15 years ago.  I've got little kids now and this isn't the priority it once was.  I just moved, got rid of my storage unit and now I'm looking for a home for these.  It's a great opportunity for someone with the interest and space.  Any takers?
