More DIY - Cab this time

Time to go buy the speaker. Thinking of a celestion Vintage 30.

Looks good. What do you have for a head?

[Simon Barden]

Probably two eyes, a nose, mouth, ears, hair etc...

You forgot to mention how many teeth!

Ooops, sorry, that is an Ipswich or Gympie joke and didn't mean to offend anyone in the lovely city of Newcastle.

It's pretty hard to find a better general purpose speaker than the Vintage 30. Very popular with the metal music guys too.

I've built two cabs, one is a 2x12" and the other is a oversize 1x12". Both were made with 19mm formply (the same that concrete'rs use) and came already with a durable Black coating.

The 2x12" (on the Left) is a vented port design with a V30 and a G12H75 Creamback both 16ohms in parallel to give an 8ohm load to the amp. As the formply came in 600mm x 2400mm sheets that set the depth of the cab to 300mm. The width of the cab was set by the width of my JVM210c combo amp as I originally had intended for it to sit on top of the cab, so the only parameter that the speaker enclosure design software could change was the height of the cab which came out to be about 950mm. Internal screws via glued ribbing allowed a fairly clean outside finish. A dowel frame with some Grey speaker cloth stretched over the front hides the two front loaded 12" speakers. The choice to make it a vented/ported cab was to try and find a mid point between open back and sealed enclosure sounds, and it does this quite well... and having two different 12" speakers loaded sounds awesome and allows for more tonal options when recording.

The 1x12" (on the right) is the same dimensions as the 2x12 but instead of the port vent has only half the back panel. The old (antique) 4 ohm Washburn 160W speaker has an interesting tonal flavour that doesn't suit all ears, and is much better suited to an open cab than a closed or vented cab. Again a frame was made and Grey speaker grill cloth stretched over it, which clips into place over the front loaded 12" speaker. The clips used are the same as those that hold doors open, or cupboards shut, four of them, one in each corner, the white patch in the top right of the Grey is one I didn't paint Black. Having the larger cabinet volume does increase bass response slightly.

Both cabs have castors and side handles for easy relocation and handling.

Not 100% sure yet, something low wattage and valve, Marshall DSL possibly.

[Dedman]

AC 15 heads aren't terribly expensive either, $100 more than the Marshals if you shop around. The Boss Katana heads are getting rave reviews, not valve but I've been tempted to go try one. There is also those tiny Vox micro tube amps, could be worth a listen. And lastly Orange Micro Terror. I have one and love it, it's actually serving as a bass amp atm.
