Planning on going down this road. I bought a pair of Deltalite II 2510s a while back to make a pair of BFM 10.5s, got 80% done with one, and lost steam (stopped gigging, don't have a good place to use the finished cab, other reasons). I'll finish it some day, but probably won't build the second, so I've got an extra 2510 on hand. Then I realized a very compact 1x10 could fit nicely in my office/work area, and the boxes in this thread would be nearly perfect. The boxes are still easy to find on eBay for just under $30, and a grill with anchors is another $7. My performance needs are negligible -- cost and space considerations are my top concerns (I still have my schroeder if I suddenly needed a cab for a show). I was going down the path of building something, but even a simple box would be more work than I want to invest in this.
My plan is to build, use, see how it goes. Then I'm going to explore chopping 2" off the back. That's completely to accommodate my office space, and some aesthetics in the room. I've been reading around, and working with WinISD to see if I can understand how that will affect the final cab. I've checked the resulting volume against the 2510's spec sheet for a ported design, and it appears to be still well within the specified range. I tinker with the tuning in WinISD, and get different port values and the graph updates, but I don't have enough experience to know how that will all play out to my ears, so I'm just going to have to give it a go.
I'm going very low cost, so just box, grill, no handles, very simple jack (using whatever I already have lying around) -- my goal is to stay under $37, with the understanding that I already had an unused 2510. Hmmm...I got the speaker for about $74, so that means I'm going to get very close to building this 1x10 for $110...
