So I built masking panels yesterday. I picked up some cheapo insulation board, for $8 for an 8x4 to attempt some super simple panels as mentioned in prevoius post. Since my frame is 3/4", I went with 1/2" insulation board so I'm not laying the panel directly against the screen (Don't want any fluffies on it). Cutting it to exact size to fit isn't difficult but having to remember the velvet will be wrapped makes a pretty tight fit.
Pulling the velvet tight is a bit hard with such light material. So I placed some books on the board to weight it down a bit. Made it much easier.
Since I used just cheap elmer's glue I had in the garage, it takes a long time to dry. So I used some tape to hold things together. Doing the ends was hell though, as I'm just not gifted in the wrapping department.
So far I have just finished the 1 panel but here is the result. Super impressed for just an $8 solution with leftover velvet.
If I place my ear on the velvet side of the panel, the sound of course is reduced, however the outer edge of the speaker is pretty much on the edge line of it and angled towards the center seat. Once I get the other one done (Just needs to be wrapped) I'll do actual tests from my seating to see if there is any noticeable audio difference, hopefully not.
