how to build a bass bend/scoop cab

[Javalon22]

I happen to have a few extra subs around and our band really needs some good low end on our PA system. I have a Peavey Black Widow 15" and an older Peavey 15" of an unknown type. I can probably only take one of these for a sub right now, but we'll see how it works out.
What I want is some plans for a good bass bend cab that will give me good response from one of these 15" subs. I have built cabs, before and we don't think the woodwork will be a problem. If anyone has some plans like this, please email me or reply to the post.

Thanks!

Hey Dude!

I would need to check my files, but, I do remember to have
an optimum sounding scoop (JBL 4520, or 4530) you need
a QTS no higher than 0.3, and a high fs (Around 50 or so)

As a matter of fact, check out Lansing Heritage site. The
C 34 plans are the predecessor opf the JBL 4530.
