Brahma 15'' box

[HotCarl 10+ year member]

i just bought a brahma 15 mk2 off a member here on the forum, and i was wonderin about box sizes for it.

my goal is low and loud...trying to top my W7 score of 144 @ 38hz by a few numbers.

i was thinking about doing 4.5 @ 32ish hz w/ 2 - 6'' aeroports.

f3 should be somewhere around 25ish

good idea, or needs improvement?

im thinking that if youre tunnig low with an F3@25Hz wich i like. you may not get that high of an spl. yeah it will be loud if powered right. but i think it will be more like of an SQ enclosure than an spl enclosure. whats your peak at @38Hz? have you graghted the freq responce already?

yeah, peak is right around 38hz...the response chart is almost identical to the W7 box, except a higher peak, and a lower F3.
