OK, then the cab alignment usually depends on what sort of performance you’re wanting from it and/or whatever size/shape constraints you have with the largest net internal volume [Vb] normally being the 843 and of course you would use the single driver baffle ‘B’: http://www.lansingheritage.org/image...ure/page11.jpg

So, is either the 620 or this one good enough to suit your needs or…………?
