Help with room treatments

I think the point of the thread was just who to spend money with.

Simple topic. Simple answer: GIK.

More on this, I recently went to the California Audio Show in Oakland. ASC was a sponsor. Rooms were terrible sounding. Midrange sucked right out of them, and yeah, almost 100% tube traps.  Could not wait to get home.

Only a couple of rooms had modest treatment, those sounded the best to my ears.

Best,

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?

I have Tube Traps behind the listening position. Also, there are Shatki Holographs in each corner of the room. All were effective, but the most effective of all were the ten Synergistic Research HFT’s placed in the room according to the directions.

I’d start there before I spent a lot of money on room treatments.

Trying to find the ideal locations for room treatments such as echo tunes, tube traps, Shakti Halographs, Skyline diffusers, crystals, DIY Helmholtz resonators, panels by ear is like trying to solve five simultaneous equations in seven unknowns. The best you can do by trial and error is find satisfactory locations but the chances of finding all the ideal locations with using a SPL meter and test tone to establish where exactly the offending pressure peaks are located are about zero to none. What you wind up with using trial and error is local maximums. This is one case where measurements save the day.
