Does Box Shape Matter

[vipervin 10+ year member]

so does box shape matter for a sealed enclosure?

i am running two type-r 10" in a sealed box. each box internal dimensions are:

6.7 H

10.5 W

16.1 L

(0.66 cu ft)

in the alpine manual, optimal specs for the external dimensions are:

11.5 x 11.5 x 12.75 and 0.65 cu ft gross internal vol

now it feels like my subs should be getting louder. i am wondering if my weird box design may be the issue.

should not matter much, if any

For subwoofers no, box shape doesn't matter.

Are your measurements external or internal ?

the ones i took of my box are internal... the alpine manual specs are external.

so i guess my next question is.. how big of a difference does vented make over sealed in terms of sound levels.. is it night and day?

it can be very drastic...ported boxes are more efficient and GENERALLY get louder. Sealed boxes are much more forgiving to design and space errors

Box shape can be very important, but you'd have to be doing some crazy nonsensical

shit for it to really mess things up.

Just thought I'd throw that out there for all you strange people.

the box shape can do it some good . it is the way it flows the air the better the air flow the better the sound and so on

air doesn't exactly flow in a sealed box.........
