What to do with Altec 816 cabs???

[Audio_by_Goodwill]

Hi All, I just picked up a pair of Altec 816 cabs with Pyle drivers. I will replace the drivers, but was wondering if there are any good tweaks or mods that might help these cabs. I will be using them and bass bins.

Also, has anyone ever used them standing on end? That would put the midhorn at ear level.

I believe turning them such that they are taller than they are wide is how they are most appropriately used*. That's how my late version of the cabinet, with factory hardware was flown.

*I'm no expert....... that's my recollection of secondhand knowledge.
