Note that in the sketchups that show the filters on the bottom that's for pole mounted PA mains. For electric bass mine are on the back. In both cases so are the jacks.
Is there a reason for that, Bill?
When the speakers are on a pole you want the cable wrapped or velcro tied to the pole, so having the jacks on the bottom aid in that. Of course if stacking that only applies to the cab on the bottom.
Could I get away with 22awg for the parallel connections
You could, in that they're so short. But it's not like 18 is all that hard to work with.

I'm using a dual speakon + dual 1/4" jackplate just for maximum flexibility. What gauge wire should I use to make all the parallel connections between the four inputs? Is 18awg heavy enough? Could I get away with 22awg for the parallel connections and the heavier gauge Leland supplied connecting the paralleled jacks to the crossover and the crossover to the speaker?
Are you using enclosed 1/4" jacks? If not, you'll want some plugs....otherwise, you'll have an air leak. 18ga is fine for short runs inside the cab.
Yep, enclosed jacks. Thanks!

Leland included gasket tape for sealing the back panel. Should it go here?
Or here?

It goes on the flange.

Thank you! I assumed that was the case...I don't know why I was second guessing myself.

Go ahead and predrill your holes for the back and the flange, then you can cut a little notch in the gasket tape for the screws to go through. I usually double up the tape on the flange, not stacked but next to each other and run the screws in between. Better seal and you don't want to run a screw through the gasket tape, because it can grab it and make a mess.

Since there's a gap along the edges doubling up probably isn't necessary. Placing the edge of the strip at the upper edge of the flange should do it.

Looking great, dude! You'll be thumping through that thing in no time. Love the tweeters. Are you going with casters or rubber feet?
