I made this 2×12 speaker cabinet (two 12” speakers) for my new Laney amp head over January and February of this year. It started when I saw the prices for store bought cabs. They’re basically only boxes with two holes cut into the front (called the baffle) that the speakers are mounted to. The rest is just aesthetics.
I had a nice piece of sapele mahogany for the case that I dovetailed together. Speaker cabs are usually made out of pine or birch ply covered with a leather-like material called Tolex. I knew the mahogany was going to make it heavy (it did), but I also knew that I wasn’t going to be traveling with it so why not have it look nice? Just to make it even more visually appealing, I added a 4” fascia across the front. I decided to veneer it. Problem: I had never veneered before. Joe at Veneer Supplies (http://www.veneersupplies.com/) was a big help. That’s where I got my veneer from. I picked out a really cool maple burl. Unfortunately, maple burls are among the most difficult to flatten. 240lbs wasn’t enough weight to flatten it, not even close. So I decided to vacuum press it (the recommended technique). Not wanting or needing to invest in a pump system, I heard of a company that makes bags and manual pumps for building skateboards (http://www.roarockit.com/). Worked like an absolute champ. For those of you that haven’t tried veneering or vacuum pressing, both turned out to be quite easy and a lot of fun. Definitely give it a shot.
The baffle is just ½” ply screwed to cleats inside the cabinet. Some speaker cloth covers the front and piping (a pain in the ass) is stapled around the edge. I left it as an open back cab. As usual for me, the finish took the most time and was the most difficult and tedious part of the project. I debated about filling the pores of the mahogany but, in the end, I just left them open. The finish went like this: Amber water based dye, washcoat of shellac, dark brown stain, 4-5 coats shellac (to somewhat fill the pores), and 5 coats of gloss poly. I was going to wax it too, but I didn’t know how the wax would react with a hot amp head sitting on top of it.
As for how it sounds? Stunning. One of the reasons I went for the Laney amp head is that it can be set to 5 watts or down to just half a watt. At that setting, I can get the tubes cooking nicely for a full, smooth crunch. Thanks for checking it out and let me know if you have any questions or if I left anything out.
