I'm planning on ordering a 2x12 cab to go with my Fargen AC Duo Tone. I know I like closed back cabs wired in series. Other than speaker choice, are there any other factors that are actually significant? Ported? I was thinking of getting the JDesigns California cab loaded with WGS Invader and ET-65. Does the actual cabinet make (materials and maker) effect the sound to a significant degree if all else is equal? Thanks for the help!
