Hello TB amps forums. I'm a bit of a DIY nutjob, to be frank, and if I grow an interest in something, I'm bound to try my hand at making it - be it beer, ukuleles, basses, I'd even like to try refurbishing a car some day - but that's in the distant world of some day, for now it's not feasible for a number of reasons (money being the first). Anyways, I've been considering getting a new cabinet (or two) for my bass rig, seeing as I've been having a hard time keeping up to two guitarists without my Warwick 410pro chuffing out at the bigger gigs (gigs at larger bars, and the outdoor show we've played a while ago) we've been playing as of late. To be frank, I don't want this cabinet to break on me and it's perfect for our smaller gigs at the moment which still make up most of our gigs. I understand completely that the best way to expand on this would be to get another 410 pro, but they aren't made by warwick any more, and they are impossible (for me at least) to find used. I've looked up on kijiji to find some other speaker cabinets, and nothing seems to be showing up. Somebody is, however, selling 4 Peavey "scorpion" SP 15825 speakers at "best offer". I've read a bit of the speaker building bible, as well as played around a bit on WinISD using the specs supplied by Peavey for these speakers, and I've got a VERY rough design for a 215 cabinet to bring to the bigger gigs. I'm a bit conflicted with this idea however, mostly because the xMax of these speakers is 3.1 mm, while the average is 4 mm, and the headroom of this cabinet would only be 400 watts RMS, among other considerations. I'm not entirely sure that this would be the best way for me to increase my volume for larger gigs, even if I DON'T screw up too much with the cabinet design, how much more SPL would I really be able to reach? Keep in mind that I'm in no real rush - I would not even building this project until at least June, and I'm permitted to borrow my buddy's ampeg 610HLF for the time being. I've considered some options - primarily building a fEARfull 15/6 and selling the 410 pro to help fund it, or perhaps design this cabinet with the concept of buying a "better" speaker later on in mind, as well as looking for some used cabinets, and I'm a bit unsure as to where to go with this project. I would like a bit of help coming to my conclusion, and to be honest, as has been mentioned, I like DIY projects a lot, and I would like to build something, though I'm not particularly averse to using someone else's design, although the fEARful is a bit expensive for me at the moment considering the cost of the 3015 alone. Ps - if I do decide to go ahead with this, I'll likely be posting updates and pics in this thread.
