I am thinking about making (rather, having one made) a simpler and more modernized version of the B-15 double baffle cab. Basically I'd be taking the cab as it is and putting it in the same box, but eliminate the fliptop and load it with a neo. Sounds a lot easier than it is, though. For those who don't know, the B-15 double baffle is a sealed 21"x21"x14 1/4" cab with two baffles. The inside baffle holds the rear-mounted speaker and has eight oval-shaped holes about 5" each spaced out around the edges of the baffle. The outer baffle is spaced out 1/4" from the inner baffle, and the sound from inside the cab is sent through the holes in the inner baffle and out of the hole for the speaker in the outer baffle. This porting system puts out a ton of low end while the small box keeps the high end intact. It works like no other 15 cab I've tried. The big 15"s have a lot of low end but that's all they have. The small 15"s sound constricted. This one is just right. The problem is eliminating the fliptop. Being a rear-mounted speaker design, if you eliminate the fliptop, you have no easy way to get to the inside. So you have two choices...creating a removable flush-mount panel, or front-mounting the speaker on the inner baffle. I would rather not have a removable panel if I can avoid it, but I don't want to change the sound of the cab even a little bit. How much of a difference would rear-mounting vs. front-mounting the speaker make to the sound? Also, what would be a good neo that could take 300w for this cab? My vintage cab has an Eminence Delta 15A in it and it sounds great, but I wouldn't mind shaving a few pounds off its weight.
