For those of us who are not familiar with my system, it is Altec 2-Way monitor crossed over at 500Hz. HF is handled by the horn and LF is a sealed enclosure of approximately 8cu.ft. with 15" Altec 411 Driver.
The cabinet came with minimum damping, about 2" of fiberglass on 3 sides and bottom. Over the next couple of months, I plan to redo the internal damping of the cabinets.
Tom's Eggs got me thinking about eliminating the parallel surfaces in the cabinet to reduce resonances. But that would be impossible to do without significantly reducing the volume. Came across this website which talks about using Anechoic Chamber type rubber wedges. Want to try out wedges and light acoustimass type of stuffing. Could not find the rubber wedges online. Anechoic wedges are too big and too expensive.

Looking for ideas of making the wedges easily without breaking the bank. Thinking of 1"x1" base and 2" tall wedges. One idea is to use sculpting foam. Any other ideas?
