open bottom speaker cab?

ok , been a member here for a while but have just lurked for info occationally. i wasnt sure where to post this question because it doesnt fit into any category neatly. first off i mostly build and repair tube/valve guitar amps but, i also repair tube radios and record player consoles. i realized a while back just how much speaker box design as well as speaker type changes tone and response of my guitar tone. so to the point i got a couple 12" 1950s magnavox speakers from an estate sale and really liked the tone. one i mounted in a open back diy 3/8" plywood box and the other i put in a 1946 stromberg carlson 1121 large console radio. well one day i decided to run my guitar amp through the speaker in that beast and it sounds phenomenal. i thought at first maybe one speaker sounded better than the other so i swapped them and side by side the console cab is the best sounding cab i have. cant drag around this thing though so i have thought about trying to replicate the speaker enclosure portion when it dawned on me this thing is not only open back but open bottom and the thick wooden legs elevate this thing 3.5". comparison in size btw the 2 is comparable. the stromberg enclosure portion is 18"x18"x18" open back and open bottom 3.5" off the ground and 5/8" thick ply . my home built job is thinner ply 3/8" and dimensions are 18"x 16"x 10.5". the main differences are thickness of material width is 2" less and depth is 10.5" vs 18". has anyone ever tryed a bottomless speaker cabinet specifically for guitar? i cannot find any evidence using google. i know the thickness of material could be a small factor and the depth being quite different . has anyone here tryed an open bottom /back speaker for guitar? results? i also wonder if the overall mass of the console itself colors the tone and by how much? i will put a link below so you guys can see what my console looks like. thank you for any input.

Hi! Although you are basing your design on an antique console, this thread would fit nicely into the 'Live Sound'; 'Instruments and Amps' section.

Perhaps a nice moderator will move it there. 🙂
