I think that would be a great solution. Your problem is that the ports will then be quite small and you'll have problems with wind noise in the ports. If you can fit in two drainpipe ports that will help a lot or use a single 10cm port. Two ports 13.2cm or a 10cm port 14.4cm long.

I found that a single 10cm port worked best for me. Single hole to cut, easier to position on the the baffle and lots of vendor options.

Well heck, this is taking a while to sort!

 

I’m going to combine a couple of projects here.  I need to make a sleeve for a Trace Elliot head, and I want another cab to pair with the Trace or the Peterson.

 

The Peterson amp has a fault, so will need to get that sorted.  Whilst it’s not operational, I might as well do the proper woodworking on the cab to optimize it.

 

Order of business;

1. Design the 2nd cab so it matches the Peterson dimensions (at least just the width so it sits nicely).

2. Go get some ply cut up

3. Build the Trace amp sleeve

4. Build the new extension cab using the Beyma from the Peterson.

 

Working amp & cab

 

5. Get the Peterson amp head fixed

6. Put the Peterson shell under the knife to optimise the tuning.

7. Acquire a 2nd Beyma (should have bought that 2nd one from you at the time @Chienmortbb!)

 

Will put pen to paper this evening when I’m in the house, also try WinISD to see if I can work out tunings myself.  Will then post my crayon drawings here for comedy value/feedback.

Sadly that Beyma went dome time  ago. The 12CVM2 is a close alternative but not an exact replacement. 
 

I have a Faital Pro 12PR320 neo if it helps or @Phil Starrmight have a Beyma.

I probably need to go up into the loft, I'm not sure what is up there any more.

That's a lofty ambition Phil!

It was a 12CVM2 that I bought from you, so should be able to source a 2nd one as they appear to be current. 👍

Ooh, should be able to get the Peterson cab to 41 litres with woodwork.  Should help, I guess.  Will make sure by checking it out on WinISD before getting the tools out!

Bought some 12mm ply, some wood glue and a circular saw.  Sh*t’s getting real!

 

Found an app called Cut List, for optimising cuts on the ply - should help minimise waste.

 

Trying to see what colours Tuffcab do, but their site doesn’t appear to work very well on a mobile.  Will fire up the laptop to browse later on.  Half tempted to do the same domestic emulsion + protection coat like I used for the “BC house jam micro cab”.

When that happens I select "desktop site" on the phone browser. It doesn't always work but usually I can zoom in on the good bits.
