Following the success of treating my cupboard space I decided to make up some temporary corner bass traps to give an idea of the benefits from replacing my GIK TriTraps with bigger corner traps. I used my leftover RS45 and RS60 rockwool insulation slabs to make 60cm x 60cm squares and stacked these in the rear corners in front of my TriTraps to form two 60cm cubes. These traps are BIG, probably four times the footprint of the TriTraps!
They have a decent effect on reducing decay times in the 40Hz-100Hz region. They do have one drawback though, - I now have +2dB more energy at 68Hz. I did a quick 'walk around' with my SPL meter and 68Hz seems to be in the height dimension, - it gets louder as you move nearer the floor. The level also changes depending on how you turn and tilt your head so I think it's my tangential length/height and width/height modes.
Seeing a 60cm x 60cm stack in the flesh is an imposing sight, I'm not sure if I'm prepared to sacrifice this much floor space! The key question is just how much performance I'll lose by cutting these 60cm squares on the diagonal into wedges.
PS - Ignore the high frequency response, - the measurements were done with both speakers playing at the same time, hence the comb filtering.
