It was a long hard fought battle, as those who have ventured know you want to quit at several points. These are built with stained Birch frames and the inner fins and wells are MDF. The precision cutting, sanding, and finish work is the most time consuming aspect. These are 10 inches deep, so deeper than what is generally commercially available, diffusing lower frequencies than with the typical 5 inch depths. I added legs and stacked the two in the corner directly in front of a stacked 8x2 ' x 6 inch broadband absorption with corner fill behind it. I don't know exact time, but for sure at least 40 hours for these two or more. So it becomes evident why it would cost about $1600 for these two if bought commercially and sadly the quality of build and materials would be LOWER!
Skyline diffusers, finishing and mounting T fusers, mounting ceiling clouds etc.... are all on the way!!
