I used the pictures from Felt-tip picture and I believe I ran everything like he did. Before soldered everything I crimped the wires tight together with pliers and then soldered my joints.

Thanks Jim.

I hooked it up to my power amp and then connected the mid section out to one of my Acme LowB 2s and then I shut it down and then hooked the Acme to the low section. It didn't make any unusual noises and I believe it sounded as it should without being able to have it installed in the cab with the proper drivers.

Well, GoldenSepter and I seem to be on the same page. Barring a little bit of shadowing around the terminal block and some bare wire confusion there. Always could do the meter between all the pluses and minuses on the terminal block just to make sure there's no dead shorts.

EDIT: Ah. Tried it out. So you must have felt good enough about it then ; }

Here's another picture. I don't know if it will be easier to see. This is the one I sent Jim.

Trying it out just made me feel a little better not much just a little.

I would try to use the meter but there are two problems with that. One I don't know what I'm supposed to look for on the meter and two I don't own a meter. :)

After looking at the pics you sent, you're all good.

As far as my own project is concerned, woodwork is now completed. My router and I have been having a ball. I routed the areas out for the handles and put it to use today to cut the holes in the baffle. Circle rigs are cool.

I also spent some fun time with my big ugly files today. Cracked a hard sweat before I had that crappy plywood whooped. Darn thing could take a piano finish now, its butt has been kicked.

I'm dropping the extra brace on the bottom. The kickback foot ought to terminate any little movements well enough.

Thanks Jim.

I look forward to seeing your cab when it's done.

I'm thinking I might line the inside of the cabinet with batting before I put the back on and then I'll only have to line back of the cab through the hole for the woofer. Then sand and finish the exterior.

That makes perfect sense. I'd take a look at even putting the fuzzy stuff on the back panel before you glue it in. I really don't enjoy emulating Houdini.

I'll post pics in a day or so before I prime the cab. I really had a fight on my hands with this plywood. I used every trick I knew to lay it up square, and still the prep stages for finish were a beast. Anything I build from here on out will come out of aerospace stock.

The Fiberglas doesn't bother me to work with and it's cheap.

Brave Lad!

Also FWIW - I suspect the acoustic properties are better suited for the job - example low entrance impedance = absorption at all angles on incidence, a property at which foam stuff is generally inferior by comparison [this is why acoustic foam panels have ridges cut in the face side], and a higher density than the poly batt stuff I have seen [too low a density = poor attenuation below 1 kHz].

In any event I have removed all the foam and poly batting from my fEarful-esque cabs and replaced with a nice thick layer of fiberglass. I find it makes for a tighter more even sound in the mids at higher volumes. YMMV
