As I said there was/is a 30Hz standing wave at the front wall - with the Tube Traps it is less obvious. I first became aware of the problem when someone brought over a signal generator with a microphone and print-out. I don't have any measuring equipment myself, so I can't measure their effect. I assume the Traps in the corners by the bookshelves are helping - without them there would still be "pressure zone" there, regardless of the bookshelves. I haven't tried any other type of bass traps - these are about 10 years old - the 20" diameter ones were custom-made, I believe for a speaker manufacturer to use at a CES show. I picked them up second hand.

Mike
