Hello ,
I'm looking for the plans of a D&B B2 sub cabinet.
For those who are interested , i have the plans for Max 12 /15 incl original filter
Q sub,C4 sub and C7 sub.
All drawn by me from an original cabinet.
So anyone who wants to share?

why do you want to build such a terrible sub?

Google is your friend. Just tried it, and found it in 3sec.
Also, i guess you got the amps for it, since you want to get a box wich sound like shait on regular amps :)

The plans you'll find online for the B2 aren't correct....

There’s no magic to the preset, it’s just a massive EQ boost like all d&b subs. Not actually dissimilar to what people used to laugh at scoop owners for doing with their preamp, in fact.

The online plans are wrong but you can buy a clone from China or Russia if you’re really bothered about huge output at one note.

I just prefer more QSubs rather than adding B2's

It’s a reflex box. Do you have the original drivers, and amplified controller?

If not you aren’t building a Q Sub. Design a reflex in similar external dimensions for the drivers you have.

You're completely right, but I was interested when someone posted this image a few years ago.

Takes some of the guesswork out of it....

Well yeah, pretty much every d&b box has a B&C unit in it. Even the new big boy GSL and KSL is using modified off-the-shelf parts. But the point still stands, if you don't process it as they do, it's not a Q Sub.

And trust me, I don't think many people on here would even remotely approach their style of EQ

Yes can buy the exact drivers and have access to D&B audiotechnik amps, just want the speaker plans.

Then measure one of the boxes you should have access to.

Or maybe, stop lying to yourself and your customers.

Buy some of these, load with 18TBX100 (one of the recommended options) and you won't be far away...
