I used a 5 ply "hardwood" from Lowes, no issues. I mixed a nice 9 ply, and the 5 ply, in my quad IB attic manifold.
I remember it was Lowes, ... the young man helping me with the ply inquired what I was doing with it. I reluctantly began to explain about subs, and the attic IB manifold, I no more than started and he interrupted and went off on car audio stories
I listened politely, explained I was into high end car audio in the 70's, early 80's. I shared with him I had a big, multi-way, active, ribbon tweeter, high-power system, w/big dual-coil subwoofer in my '76 Chevette, 30 years ago! He didn't know subwoofers existed back then! Yeah, we had subs in the 70's, ... we had had belts too, we used them to keep our pants up
Best of luck over the weekend with build progress, you've got the chops ... attention to detail, all the design talk, tips and tricks, and build updates are much appreciated. This is one to watch, your Kung Fu is good.

Side by side or one in front of the other it's amazing to me how much their response can differ. Stacked vertically though, always really close.
My vote is a vertical line of drivers.
Makes sense to me, I mentioned something similar back in post #10, these big physical elements up front, there may be significantly varying results, due to varying physical configs, interactions, etc. Also, quite likely out of sub band impacts as well.
Good luck with the vehicular issues. We've got a little snow the last few days, I just discovered my 4 wheel drive is acting oddly,.. not fully disengaging properly, in a timely manner. Winter always fleshes out this stuff.
