I have been using Audiopoint inverted couplers, the APCD4s for several years and with proper placement and the right tensioning I can extend the soundstage down a couple of long walls..To tight =s too bright.. back the tension off a touch and there you are. Or I can focus the center stage. If you want it wrong keep adding more and it can sound like stretched pseudo surround sound..your choice you may like that sound. These can be threaded into mounted panels or use brass threaded inserts into materials and then thread the coupler and tune to your delight..Look at the overall shape and the center is inverted and will capture, focus and disperse energy or with another of our devices ground the resonant energy. Brass is the metal of music and Geometric shapes matter.
