box question

[Jep772 10+ year member]

for some reason i think i got hustled w/ this box. i been looking around here alot and i've seen some of the members boxes, one i saw was a single 15" and the box was like 3.5 cubes or somethin, but it made mine look tiny... the dude that built it told me it was 3.148 @ 34hz. which is more or less what the woofer calls for..

heres the specs: 20.75" wide, 17" deep, 17.5" tall.. the port is 1.75" x 16"

what is the real size of my box? woofer displacement is 0.13

i dunno the formulas or w/e but im thinking its closer to 2 cubes, and if thats the case would i be better off just sealing up the port and running it sealed? optimum sealed volume for the sub is 1.75.

ok thanks.. he went right between the optimum, and minimum specs. ima go up there in a few mins, $130.00 it shoulda been what i asked for.

how long is the port? its less than 2.5 cubes probably.

14.5"

you think it'll still sound decent tho? or would i be better off stuffing the box & sealing off the port.

i got around 2.75 cf before port and sub displacement

and assuming his port is round, it would come out to be around 2.5

i wouldnt really plug up a port, and i wouldnt waste a 15" sealed, but if you have the extra room, make the box bigger, and tune appropiately
