JBL L200 DRIVERS

This. How much floor space do you have to devote to the speaker cabs? You can simply design your cabinets around that space. Just build up until you achieve 5 cubic feet, add the ports, and go to town.

If you don't have the proper equipment, you can get the panels pre-cut at the home center.

I like the idea of designing the 5cu ft box to fit the space.. That is what I'd do with those drivers! With just a few basic tools it should be an easy job..
I'll bet I could do it with these 4 tools..
Cordless drill, circular saw.. Cheap one at a garage sale.. One of these little Kreg guides that clamp onto it, and a pocket screw jig.. I have a better one but this one is only $20 and would do the job with a clamp. Then glue and screw all joints.. Cosmo Kramer couldn't F it up!

Then either paint, or veneer, and that wouldn't be difficult, or take the box to a shop and have them veneer it in anything you want.

Edit: Ok then, boat builder! Never mind my quaint little post here! :rolleyes::biggrin:

Not at all man! I love how you think. When you think of the simple tools they had in the 9th century, and the cathedrals they built, you're on a very good track.

One of the challenges I set myself is to use only what I have at hand, it's too good just to sit on shelves. I even have the veneers — and it's classic JBL walnut. Hopefully all I'll need from the outside world is glue and screws (though I have a nice little dowelling jig I haven't used yet).
 
Well. So you have a cab about half the size of a L200....'bookshelf' territory (?).
Short of modeling it (ugh!) not sure how you'll do better than picking several woofs, measuring and swapping out.
But, that CD and short horn, and 077 should fit fine, so a matter of which woofer, and ports (or not).
Maybe make a 'universal woofer mounting plate' to help with various cutout sizes (the EV you show above looks like it wants to be mounted on the back of the baffle?).
Hm. Hey, how close is that volume to a JBL L65 Jubal (Alobar?!)!?
Maybe also dig through DIYAudio for someone doing something similar?
Personally I've been curious about the 'other' JBL neodiddlium Dual Drive woofer - the 12" 2213ND (as in the 4312E), but looks like those are NLA. That dual drive design is nothing short of amazing (read up on their white paper about it).
Getting to or below 30hz in that cab size might require a servo-type woofer (just speculating) - and I see that someone makes kits for that now??
Build it and they (woofers) will come?
Best Wishes!!
 
Go 4 ft tall and a 5 ft^3 cabinet doesn't look so big. A little thought and planning towards removable baffles would make it pretty easy to swap around components until you settle on something you really like the sound of. Get one of the Dayton Audio DSP-408 4x8 units and get your tweak on. Crap...I'm trying to get rid of speakers and I keep coming up with ideas for building more.

Interesting idea about the L65's. . The 077s came with those and an H91 horn just might fit where the little 5 inch paper cone MF driver went. A 12" JBL ND driver, wow! I got a lot of ear fatigue with the 5 inch mids. . I'll bet the LE85's would cure that for me. Hmmm
 
So many good ideas. Just that simple one-cap xover for the 077 cured a big headache. I'm compiling them all into a Word doc I can index. I can't overstate how helpful you've been. I've given thanks profusely already, no need to repeat it.
