RE: Optimum Size for 2x12 Cab (Vet 30 / Ret 30 / Vintage 30)

Hi guys,  new to the forum here.  Love the name, Warehouse.... I want to build a speaker cabinet 2x12 or 4x12.  Powered by an Orange cr120h amp.  I am thinking of combining the veteran 30 and the retro 30, any concerns with that combo?  Also, how much cubic volume do I need for optimization for eack speaker?  thanks in advance!

 

I ALWAYS recommend folks build a box about the same size as the wonderful Marshall 1936 ... the ultimate "big-box" 2x12 cabinet!

Here are the dimensions of the model 1936 given on the Marshall site:

DIMENSIONS in mm (W x H x D), 740 x 600 x 305

The only thing I would add is a 3-piece back with the option of running the cab 1/3 open-back!
