"I built some DIY HFT resonators using ozzy’s recipe (copper fly fishing cones inside of 1/8" copper plumbing end caps). Total cost was something like $20. They definitely effect the sound in my room. Pretty powerful actually. Easy to overdo it and the mid-treble gets hard sounding IME."
Geez, I almost forgot the most important thing. The trick with these resonators is finding places in the room where they do good, not do bad. There are many places where they can hurt the sound. Like the empty beer bottles in the big rooms at CES. 😬
If you have an SPL meter handy you can map out all the pressure peaks in the room and attack the highest dB peaks first. If you don’t have a SPL meter handy it’s a lot of trial and error but the best places to start are proximity to room corners, especially upper room corners. Other places to start are 1st reflection points, the wall behind the listener and between the speakers on the front wall. Height is an issue with around 5 feet being a good starting point.
