Pair of WH6 Lites build
Posted: Sun Nov 08, 2020 9:02 pm
Started on a pair of WH6 lites, using 1/4" BB ply. I easily got all parts for both cabs cut from one 5x5 sheet of ply with about 25% of the sheet to spare. I cut the driver spacer and phase plug out of ½" BB scrap instead of doubling up and laminating ¼" pieces.
For one of the cabs I picked up a New-Old Stock Alpha 6a on ebay for $25. For the other cab, I'm rolling the dice a bit... I'd really like to have neo drivers in these, but with the Alphalite 6 no longer being made and remaining stock a bit too pricey to shave a couple pounds, I searched for other options. I ended up choosing a driver that's slightly out of spec, the PRV Audio 6MB250-NDY. Figured I'd take one for the team, give it a try, report back it's performance, and weigh in on whether I think the weight savings is worth it or not. At 1.2 pounds, it's less than a third of the weight of the 4.1 pound Alpha 6a.
Sorry for the cruddy photos. My phone has camera issues. I'll try to remember to bring a better camera next time.
I got all the pieces precut to their rough cut dimensions. -
Got the sides cut out. -
Here's what I'm going to do for the hand/port holes instead of half round stock. I added an inch around the handhole/port dimensions and cut it out of ½" BB, routed the outside lip on one face, and drilled the 2 center holes to locate it to the side. I only drilled one locating hole in the side and will use the hole in the backing to guide the 2nd locating hole so they're all lined up and perfect. Then I'll use a paddle bit and drill them together once they're glued together.
I held off on gluing them together. I want to check the SketchUp to make sure the modification won't interfere with anything else in the cab. -
I also got the top and bottom cut to final size with their angled cuts (not shown). For the outside pieces, I just have the top back and bottom back left. Then I'll start on the horn pieces.
Stay tuned. More to come soon.
