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? ------------- “The fact is this is about identifying what we do best and finding more ways of doing less of it better” |

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. |

but, unfortunately, the wrong note. ------------- Chas n Dave : it's like Drum and Bass but with beards. E=mc² ±3dB |

| 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... http://bluearan.co.uk/index.php?id=JMSKIT118&browsemode=category" rel="nofollow - http://bluearan.co.uk/index.php?id=JMSKIT118&browsemode=category |

Rent a Q sub, and use your tape measure. Or just build any 18" reflex sub with the same external dimensions. |

If you can't afford to rent one speaker cabinet, then you should be looking elsewhere for your design. Not that you should be trying to copy it anyways. It's just a small reflex box with a B&C driver in it, that's all. Tons of those out there, and simple to design your own. |

That’s not illegal! If you reproduce the box and put the logo and say that is original it is illegal. If you read the plans to study it is not illegal! Bye bye!!

| You’ve literally been told everything you need to know. If you can’t find the dimensions on the d&b site then you probably should put down the tools. |

| Are you willing to try designing it yourself? |
