I added some measurements to the photo, if needed I thought i could get a piece of 3/4" mdf and cut off the four corners and curve the inside using a jig saw and place one in each corner. Each one would fit between the two existing braces in the middle of each panel, i tried to show this with the blue lines i added. Thanks again
You won't need it. The 2 side panels fit inside the side with the rabbet. These help fit the joint together and are supported by the rabbet on the dadoed panel. The brace that you have already extends from the bottom all the way to the top at centre. So you have 3 contact points on each piece. I think you are good to go. If you're going to do it, I would just double check the 90 degree to make sure that it is accurate.

nice diagram and thanks for the dimensions.

Yup that is the one i got without the mounting hole.
Any thoughts on the bracing, not sure if more is needed. I plan to assemble the box with glue only, need to pick up a few more clamps.
Sorry, lots of family stuff

That bracing should be adequate for the W7. It ties all 6 panels together which is ideal. You could add some additional strips in the corners as well if you wanted to provide additional surface for each of the panels to tie together.

You could certainly do as your mock-up shows if it provides extra peace of mind. It would add more strength though is not a necessity. The minimal extra effort does add extra strength. Not necessarily an audible difference but should help with rigidity.

any input on good binding posts for this application i came across the ones linked below i was thinking i could just drill a hole for each through the back but reading more about them it sounds like a plate is also required, not sure if it is 100% needed. I was not sure if the typical speaker terminal with the square plastic would be strong enough since this will be a sealed enclosure.

I was just wondering if you have made any more progress on this project. I have been wanting to do the identical build myself. I’m finally getting a dedicated sound/theater room set up in a new house and the space is much bigger than anything I’ve had prior and need a serious sub upgrade. I had been kicking around the idea of 2 W7’s and a Crest CA12 for quite a few months now.

im embarrassed to say it but its not complete, but i will be starting up again tomorrow.

i paid a local place to cut the circle in one of the front pieces, but it honestly looks like they cut it with a steak knife and i cant use the piece. So now i have to cut a new piece & the circle which is what i was trying to avoid since i hate making the straight cut, this one has to fit between the two ends adding to the fun.

Tomorrow i will be picking up the wood wish me luck.

You don't know anyone with a router? Pretty easy to cut a hole in the baffle with one even with a home-made jig. Not sure I understand what the straight cut/fit between two ends particularly means, tho....
