no significant difference my room has very little decay issues as it a good size, quite a bit of fiberglass and sound can escape it's not really soundproof. thanks, john
Thanks for doing the video, I'm about to do something similar, good idea with the bags, and that base looks nice and sturdy. I'm moving to stands partly so I can move to as small a desk as possible as I when I measured with REW I thought the desk reflections were making a big difference specifically a big dip at 80Hz then big hump at 120. - Do you think that dip at 100Hz on your graph might be the desk reflection?
thanks for the excellent question! 80,100 and 120 are not desk reflections. they are more than likely room modes the low freq cancelling itself out due to the size and shape of the room. search for "amroc room calc". on google. you can put your room measurements in and it will show the problem frequencies. keep me posted. cheers, john
Wow that is an old trick, I did that in 1990. I used waste Photocopier Developer! Similar to Iron sand nice and heavy!
Good job!
Interesting, thanks. Would have been also iteresting to see the differences in REW's waterfall (decay time) graph.

I made my desk stands from birch but I think best would be mdf (or something else cross fiber structure) board to be more dead.
