From what you've listed and knowing my ALtec preferences, i'd go with the 288/MR at ~500hz in a heartbeat and apply some careful eq/contour. That's the combo that will do tear sheddingly real midrange if you get the XO right.
So I want to test out the 828 cabs before I spend time refinishing them. I plan on loading them with the 515Bs on the low end.
I am going to restore the Heathkits to their original configuration and sell them...I think. This will free up the 802Gs I have in there now and help pay for the 604Ds I just bought.
The high end on the A7s is the question. I can try the 288/MRs on top. But I think I also want to try loading a 511 or 811 inside with the 802Gs. If I do that, the "port" on the bottom will now be closed up. Do I need to create another port or just use the "leakiness" of the cab as a natural port?
Also, what would I expect to see as the difference in an 811 loaded A7 vs a 511 loaded one? 1) assuming the same 800Hz XO and 2) using a 500Hz XO on the 511? I hear the 515Bs have a "lovely voice". I'm not opposed to letting that shine to 800Hz or even higher if it works better. Would I get more extended highs with the 811s?
Again...just thinking out loud.
BTW, anyone know the PMS color to use if I wanted to restore the A7s to their original color? PMS Color Chart

True dat. I've been reading Jim Smith's "Get Better Sound" and he talks a lot about "musical involvement". Not just listening to music, but the level that the sound engulfs and involves you.And ain't that what it's all about? I call it the goosebump effect.
Some sound only reaches your ears, better sound can reach your brain. Great sound will make it all the way to your soul and affect you long after you turn it off. It will stop you in your tracks and force you to sit and listen deeper. That is what Altec has done for me.
That said, I'm sure the signal chain including amp/preamp has something to do with it as well. I never had the chance to listen to my new speakers on anything but these nice tube amps. It would an interesting experiment to hook them up to my old Onkyo receiver and see what I get. Maybe when the A6s get to the garage I'll try it.
Speaking of the A6s, if I keep the 288/MRs for the A7s inside, I'll need a horn to go with the 802Gs that will likely be going out there with them. Just pick up a cheap pair of 511Bs and keep the XO at 500Hz?
The port dimensions are part of the design. They can be changed, but you should not be sealing up the cabinet simply because you don't have a horn there. The leakiness of a cabinet is not a port, it's a poorly sealed cabinet.

I think the plan will be to open the back, add bracing and damping material to the cab (maybe battens at the seams) and horn and add ports on either side of the MR. There should be plenty of room. The only issue I see is the MR will be a little tall for the existing opening.
Wow, that sounds like alot of fun!!!! I especially like sheddingly.... should be added to the audio expressionist's dictionary...

Yes, I fully concur with you. Bowtie has an uncanny ability to express things so well, so well its almost like seeing a 3D image in front of you. I at times I think him to be a writer, or may be he is actually so, on the side !
Anyone putting rollers on the bottom of their cabs. I like these ball transfers:

Along with keeping the dust bunnies under control, they might help with isolation.
