Description

Boost Me (for free)

If you would like to see more models like this, please consider giving me a boost! 

**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.
