**this is a work in progress**
I will continue to update this as I complete the design.
I found that I was putting my desk speakers at an angle so they would point towards me, so when I started designing an enclosure for the CHR-70 drivers I thought I would design the enclosure so each speaker could sit squarely on the corners of the desk and already be oriented in the ideal direction.
I am currently running the radiators with no weights attached but I plan to spend more time in WinISD as well as taking physical measurements with UMIK-1 and REW to determine the ideal weight.
Components:
