What to build (eminence 4012)

Greetings all, it's been awhile.

I have two blown definimax/magnum 12's here that should be used for something. I do recall these came out of a now long-gone T30, but would they work in any other cabinets?

Is there a guide to which driver are good in each design anywhere? Besides what's list in the first page of the plans?



I kinda want to build a couple of Jack12's, be their a bit below the recommended Vas - not sure if there's a different non-tuba cab for them to work in, or if they would fit in either of the t39 build types.

They'll work in Jack 12, though a bit weaker in the mids than the recommended drivers.

I'd like that in some form of technical data? how many db up toward the crossover frequency?

A couple of Jacks would be easy to build, and would be nice to have a few more tops around. not like a couple sheets of ply and some piezos will break the bank

Compare the SPL charts on the Eminence data sheets.
