Head Cabinet Drawings

[clobo]

Hi,

I too would be greatly interested in a 2x12 slant cab. Needs to be the same size as the 4x10 found in the download section, but fitted with a straight 2x12 (disgonal), with that obscure "fake slant front" shim.

The construction details of that "fake" slant cab has been the most keeped secret on the web .

I have already built the "real" 4x10 slant version (with 36W head), but I would like to change the baffle for 2x12.

I can share the real slant construction details

clobo,

The trick to the Fake slant is that the baffle is one piece with a raised grill cloth. The grill cloth frame is made to include the slant. Go to my gallery and look at the SIII-One gallery. I made like a Marshall mini-stack with the top cabinet a slant 1x12. Otherwise the cabinet is made like scaled down 4x12 (see the plans in the downloads section).

Thanks Richard,

I looked at your pics, but I don't see how is the grillcloth actually supported at the "break" angle. Did you add another horizontal frame piece later on ?

If yes, then my understanding is, that horizontal frame piece would be partially covering your speaker hole, right in the middle.

Then for a small square cab with 2 diagonal speakers, that horizontal frame would still be covering top and bottom of each speaker (respectively).

Or am I still missing something ?

On the small 1x12 cab I didn't bother with the center brace. The cloth is naturally stiff enough to not be necessary. It is just supported on the sides.

I did build a slant 2x12, but it is just 26 1/2 inches tall. Pretty tight fit. It has a center brace. You can see it in the gallery behind the SIII One in a few pictures.

On a 2x12, I wouldn't worry about the parts of the speakers being covered.

Thanks again Richard,

My cab is 25x25, I used 4x10 dimensions found in red on the 4x12 plans from the download section. Now I will build a new 2x12 diagonal baffle, following your idea.

I also found a picture of the real thing. From the back we can see the horizontal frame, and also the logo support plate.

I couldn't wait any longer to sink the 2 Celestion Relic 30s I've had for a while into something. Basically, I followed the 2x12 combo drawings in the download section here, but alterd the dimensions a little. It turned out sounding great, but looking just OK. I'll eventually re-do the piping on the front. It's not real piping, the real stuff looked too fat on this cab.

What wood/thickness did you use for the exterior pieces(the outside of the box) for the amp head cabinet? Thanks for the plans.

zappacat,

If you're building one to exact Marshall specs, they use 5/8 inch baltic plywood, but for a 2x12 you can use either 1/2 inch or 3/4 inch. Most metal corners are made to fit 3/4 ply.
