I was wonderin what would be louder a 13" W7 or a 15" Brahma? recently bought a brahma nd a friend of mine is buying a w7 he bet me his would be louder

Pioneer P8-MP

15" Adire Audio Brahma

6.5" Infinity Perfect components

6"by 9" Infinity Perfect Coaxils

Hifonics 1800D

Hifonics ZX 6400

2.5 cu ft ported enclosure

Optima Yellow top battery

Stinger Alternator

18 yrs old nd this took me 2 years to save up 4 but well worth it!!

Too many variables. I'd say the loudest one will be louder.

this comparsion has been done before on other sites, but I personally would run the brahma, much more sub for the money, and I think its still less than the W7,

edit: moving to sub section

hmmmm well being that the more air you move the more bass created

2 find this out

take the cone area in cubic inches

and multiply it by the xmax

and the total is the amount of air being displace in cubic inches

for example:

jl audio 13w7

cone area is 107.5cu.in

xmax-- 1.25in

total air displacement

134.375

brahma 15

cone area is 116.1(kind of small 4 a 15 dont ya think)

xmax--1.10

total air displacement

127.71

hmm this interesting.....13w7 move alittle more air than the brahma 15...but the human ear will not notice it....but in actualty the brahma 15 should move move given the same power as the 13w7 due to having a slightly larger cone area...but this is all numbers crunching i would have to hear these two against each other.

there are a few people on another site that have done head to head comparos and the Brahma has seemed to win more than not
