I am looking to build the smallest and lightest great-sounding 112 combo cab possible for my EF86 18w build (early ac15 pre with 18w Marshall power). Cool as they are, vintage AC15 and 1974x combos are way too big and heavy for me to live with. Prevailing wisdom seems to suggest a small cab can sound "boxy" yet I see amazing offerings such as the Texamps EF86 at 19x19x9 and Sock Monkey 18/12 at 18.75"W x 17"H x 8.25"D (and only 28 pounds!) In this boutique spirit of "smaller, lighter, better," just how small can I go? I plan to use one of these older Rola Celestions, one is a 75Hz and one is a 55Hz.... Any opinions on which speaker would sound better in this application would be appreciated too. Thanks everyone!
