Mr. Griffin contacted me recently and inquired about cutting/assembling some Array cabinets for him. He desired something similar to the "Epiques" but wanted to utilize a different driver (SB65WBAC25-4) along with make a few minor changes to the cabinets (1" wider, braces, roundovers). After a few emails back and forth, I presented him with a CAD model for approval and we started the project.
I didn't take a lot of pictures during the build process, sorry guys. Jim did give me permission to post what I have for you to see. If you have questions about the cabs, I'll gladly try to answer. If it's about the details of the design and the "why's", Jim will chime in to answer those.
Here are the CAD screenshots (in greyscale), not sure what color Jim will be painting the cabs. Believe he has a local painter in mind.
One of the first hurdles would be coming up with a way to secure the removable baseplates to the towers. Jim was prepared to use bolts and nuts which would require him to be able to get his hands in through the back of the tower to start the nuts and tighten them. I suggested we look at incorporating a plate with nuts welded to them so he wouldn't have to do that. He liked the idea and after giving this some more thought, I suggested the plate be changed to a bracket with legs that could also be secured to the sidewalls. This would increase the overall strength of the assembly and spread out the work load. Had some 1/4" thick 3"x3" angle iron on hand and decided to use that. Overkill, yep. 1/8" steel would probably have sufficed but the extra weight at the bottom of the array isn't gonna hurt us.
After cutting 1.5" off of two pieces of the angle iron, they were welded together and then milled flat on the bottoms. This was followed by drilling holes for 5/16" bolts, tapping the holes and then welding nuts for even more threads to engage with the bolts. Sandblasted them next and then applied a Rustoleum paint and primer in one.
More in the next post.
