Well, in the midst of planning to build myself a fEarful 15/6 my scheme was pleasantly interrupted by scoring this wonderful unloaded Sunn Cabinet off my local CL for $25.00... The covering will be fine after a scrubbing and a dose of Meguiars #40, but the box needs to be reglued & rescrewed. I also plan to install a Speakon NL-2MP, which conveniently is an exact fit for the hole in the rear panel and replace the speaker mounts with the proper number (8). I considered a NLJ2MD-V, which might be a better choice, but I already have the NL-2MP in hand A few questions, TIA for any input, comments or answers. It's a weird size. 24" wide x 28" tall x 10" deep internally measured. Counting on my fingers gives me 3.8888 CF internal volume which should be enough space for a Kappalite 3015 (non-LF), which I ordered while they're still on sale at Beach Audio. It has a cute little 3" x 3" round port already. 3/4" plywood. Anybody know which model cabinet this is? The port calculator at http://www.mobileinformationlabs.com/HowTo-1Woofer-Box-CAL Port lenth 1.htm tells me that I'll be able tune this box to 40Hz by trimming the existing port tube to 0.87" This seems as if I'm missing something somewhere. Is that really all there is to it? I want to seal/fortify the original wood screw based joinery as best I can. The back is screwed on with 26 screws ( all but 4 missing on this treasure ) I'm planning on getting new screws & trim washers in the same size as the originals, dowelling/gluing the holes in the cabinet & rescrewing - pretty straight forward. I'd like to glue the baffle into the cabinet along with redoing the 16 screws that hold it from the inside, but the grillcloth is stapled to the baffle instead of on it's own frame so that seems like it might not be the best idea. I'm thinking of installing threaded inserts in the baffle and using machine screws instead of wood screws for this, but I'd love a better idea... The baffle is flush with the front of the cabinet so there's no room for a separate frame for the grillcloth without major surgery that I'm not up for. I'm probably gonna install T-Nuts and use machine screws to mount the speaker. The foam is starting to deteriorate but is still spongy. My first inclination is to leave it be, but refoaming while it's already apart should be no big deal. It also occurs to me that there's room for a mid-enclosure and one of those nifty 18Sound 4ND410s in the box with room to spare, but that might be a phase two if I don't like it plain. I'm gonna be driving this gem with a Shuttle 6.0, but I'm not planning on needing to be real loud without additional reinforcement. Thanks again for any help.
