Not uncommon with altec. The A7 uses this arrangement when the horn is stored inside the cab.

If you'll be taking measurements while experimenting, you might do so in it's natural state, as a baseline. Or just mod one at a time and a/b.

...yup, the drivers will stick themselves to the baffle. When the goop has run (over time, temp) it can rip pieces of the cork or baffle out. Gentle is good when they are stuck, saves headaches down the road. Gravity is a friend, but you have to be ready to catch or otherwise land ~30lb of woofer.
Mine too...just a little. I'd love to build Bruce's 300b monoblocks, but at (4) 300b tubes per channel and $150ea for cheapies, I might have to wait till I hit the lottery.

So if I wanted to do some measurements, what would you recommend. I've never done anything like this before and I don't have a proper mic. Would my Macbook Air do? What software?

BTW, the drivers released with a little persuasion. Very little. Cork completely intact.
