New BassChat 8"Cab design

[Phil Starr]

It's never a bad thing to seal up the cab. I usually use draughtproofing foam strip to seal my connector plates and the baffles and rear panels which on my personal cabs are just screwed and not glued. 

 

Interestingly some allowance for leakage is made when calculating the cab sizes and tuning Using a factor called Ql. WinISD defaults to Ql=7 which is what I've always done anyway and by and large the measurements on the cab come out very close to those expected. You can't seal everything and the magnetic gap in the speaker itself is almost always open but sealing things where you can is good.

It will help prevent rattles as well, if there is no gasket supplied with the plate.

 

Please could you share your wiring diagram for the speakon sockets please. I have no idea how to wire them together so that you can daisy chain cabs.

Connect the two 1+ together and the two 1- together. Connect the 1+ to the +/red of the speaker and 1- to the -/black.

 

And I use thin neoprene draught proofing strip. Unfortunately I've bought both 1mm thick and 3mm thick so I don't know which one I used on my previous builds, but it was 10mm wide.

It's best to minimise leakage, but most have some porosity around the connectors, especially if using jack sockets.

 

If you use a vinyl covering then the edges will seal well enough, but if on a hard surface a bit of sealant wouldn't be a bad idea.

I'll try and make gaskets for the jack sockets and for the plate. That would be neater than sealant, which knowing my luck, would mean I'd attach myself to the cabinet, never to be released. Much like Hans Solo in his Carbon tomb .

If it helps this is the back of the Speakon sockets. They are neatly marked as +1 and -1 the +1 is connected to the +1 on the second socket and then to the + or red terminal on the speaker.

 

If you use a jack socket then you are very naughty, but the tip of the jack is the +1 and the sleeve is the -1.

It's also just possible to use spade terminals which crimp to the wires without soldering, though I recommend soldering if you can do it.
