They're worth having IMO; certainly in a box with panels that size.

Flush Trim on all edges worked out perfectly. That has to be one of the most useful bits ever. I am now going to finish sanding the driver rabets to ensure a perfect fit then clean the, up, shellac them, and set them up! So excited!

Ron,
The build looks great - nice job! I was going over some old threads and recall you were talking about building the WIBAQ (essentially the same thing but with shelf-port). Did you abandon that due to back order of Betsy driver? Looking forward to first sound.

Yes, I also wanted a pure full range driver without the use of a whizzer. I read in a few places that whizzers could be prone to shout-iness. The back order also didn't help as I was impatient and was itching to get started.

That said, doesn't mean I wont build those in the future as well.

My brother has the Betsy-K's so building that cabinet without the driver might still be a possibility.

That said I am blown away by the build quality of the Mark Audio drivers.

Have you started breaking in those MA drivers? I hear they need like 200 hrs before they sound right. Good to hear that you like the build quality, I may have to get these one of these days when I have a shop that can make stuff out of wood. I don't think a 4 foot tall box this big would work very well in foam core Good point about the whizzer, but I have not heard anybody complain about the whizzer on Betsy's in particular. You are impatient - working at breakneck speeds with your build there Amazing progress.

All the bad clamps went back to lowes, not enough clamping pressure with the Bessey's and the Irwin's... Going to woodcraft to get a nice set of the Jorgensens tonight.

Some more build pictures soon.

Update the tools section with the circular saw I ended up getting, and a great blade for plywood.

This build has been completed to a listening state. I will be running them like this for a while during the "burn-in phase". So far I am just blown away by the Mark Audio A12p's.

Imaging is just ethereal and absorbing. I have never heard anything like it.

I posted some final build pics. Last things left are some wood filler, sanding, and stain. I will be holding off on this until I have listened long enough.
