I would try synergistic UEF Panels and Dots - very musical - put em on the walls as outlined in instructions for a couple of days - and then remove the panels - the sound stage collapses. You will want them back in.
I tried the HFT's - they work as advertised. But I preferred the UEF panels. YMMV.
I have 8 UEF panels and I think 10 dots.
