I have mentioned Space Couplers a good few times now. I would love to test them, but the woodworking is beyond me. I am waiting for some tests from Gavin at Auralex. I have an article here which describes how the author (designer?) Jeff Syzmanksi, reckons they work. To me, it is all hypothetically plausible. However the increase of LF absorption of 40% in the 125 Octave band really caught my attention. If this is true, plus the promised 'liveness' this is truly a device worthy of experimentation. Hopefully Terry will show us that.
Terry, I would rather see FuzzMeasure, 3 in particular used. However, assuming I will assume REW and get to know it a bit better in order to help you-
Mark your measurement spots on the floor with tape. Tie some thread and a weight to your measurement mic. This will ensure that the mic measures in exactly the same spot before and after the introduction of the Couplers. Drive the room well by putting the speakers in the corners, on the floor, if possible. We are interested in modal decay here not frequency response. The more Couplers and Traps involved, the more meaningful the test. Four corners floor to ceiling would be ideal.
I very strongly encourage your efforts here. I have a good feeling about this.
40% more LF action. Better looking. Some HF diffusion/liveness.
A lot to like!
