I have a quad of nice JBL woofers from EVOI 324 cabinets. Cool neo differential drive 14s, and I want to use them in conventional wooden enclosures (I only have 1 of the horns, which interlocks with the woofers).
The problem is the baffle, vents, and mounting are all integral to the frame. It has two flat sides, one somewhat curved side (top) where the midpoint of the frame protrudes 1/2" further out than the sides of the frame, and a bottom with all manner of silly shaping (for bolting together with the horn, in the completed evoi system).
Any thoughts on how to mount a very odd woofer frame?
lots of pics on the googles below

Interesting way of making sure you can't just pull the driver and use it in something. Short of building the enclosure with the same curve as the baffle, can't see how you'd do it.
I don't think that was the intent- the interlocking system and rods bracing to the back of the enclosure is very well thought-out, unfortunately, it makes them nigh useless for using outside of the stock enclosure with horn.
The issue would be simpler if the "bottom" (where the vents and supporting rods are) were curved/mounted the same as the top, but it's not. I am leaning towards rear-mounting onto a curved panel and giving up the "free" incorporated vents, but that's a shame as the integral vents (the whole aluminum chassis for the baffle in fact) are part of the cooling system.
Pro sound service had the horn listed and I'd be okay with keeping the cabs, but as it turns out they only have one in a cabinet and wanted to charge packing/shipping (normally free) as well as shop labor to remove it in addition to the cost of the part, doubling the cost. I'm not willing to take that path on principle, much to the dismay of my plans.
We are thinking the same thing, just worded differently.
Yes, there are pictures of the back on Google.
Taking a closer look at the full EVO documentation Evo Home * while thanks to modern DSP, some of the system functionality is now readily available to DIYers and small OEMs at very affordable costs, I think it might be at least shortsighted to under utilize the total system engineering by cannibalizing these drivers for uses other than those originally intended.

Perhaps rear mount the panel rather than front mount in an enclosure... or the obvious alternative - infinite baffle panel hung from a roof in a factory. These are a PA driver?
Enclosure a bit on the difficult side, possible but not all that practical.
Standard driver cabinet project a better use of your time and money perhaps?
I hear the words of my old Uncle Bob.... Why would you use that unless you got it for free?

Unfortunately the original system is not an option as the horn is unavailable. They're P.A. drivers for sure- but there's nothing inherently wrong with that, these differential drive woofers are of excellent quality and well worth experimenting with.
