Sorry, not trying to be rude but I feel like i'm going crazy while reading this. You're telling me going to Home Depot and paying to have a new back made is easier than removing a dozen screws? Everything you said applies to the CB, if you only want to attach the back with a couple of screws, you can do that. The OB has two plates that run across the top and the bottom and the top has the input jack, so you still have to deal with all that of too. The jacks are only held in place with a couple of nuts around the shaft, just pop them out and plug a cable in there's plenty of slack inside. Or make a top plate for it like the OB, if you want to make something.fiveightandten wrote: ↑Thu May 11, 2017 11:00 pmTo make the OB convertible, you have the guy at Home Depot cut down a 3/4" piece of birch plywood. It takes 2 screws to put it on or take it off. You can do that with a screwdriver at a gig in about 30 seconds.
It's more laborious to take the back off the closed back cab. And then what are you going to do with the input jack? You have to keep the back of the cab right next to it after removing a bunch of screws? Then you're tugging at the wires and trying to position the back in a way that you can have the speaker cable plugged into it. That seems silly.
The closed back has a sound that the OB can't do, and vice versa. People who have the open back can easily make it sound closer to the closed back, but not the other way around, IMO. If you like the sound of the closed back, that's not an issue in the least.
I said earlier that the OB wins hands down on portability, I just honestly don't understand how you can say it doesn't "work the other way around" because it does. It's a wood box with speakers inside it, the exact same speakers in both models. The only thing different is that they're parallel in the CB like they are in the 4x12, and offset in the OB to save space inside. I'm not trying to be a jerk, maybe some people like that the speakers are closer together? I don't know.
