12' Vs 15'

[sheeraz552]

Currently got a sealed 15' JBL sub but might swap to a 12' ported (JBL)
RMS are the same
What would be better? (hitting low notes and general loudness)

[kizza]

i was once told that a decent ported box are louder than seal boxes, not sure weather its true or not.

Ported box will be louder if it's done right. Sealed generally gives you better SQ.

which sort of JBL is it mate. 15's have a bigger surface area than the 12's so they will push more air out. the jbl gt5's for example: the 12" version is best in a 1.7- 2cu.ft ported box. the 15" version is best in a 3-3.5cu.ft ported box. upto you what you want to tune the port to. i recommend 33hz =]

also ported boxes are alot louder than sealed. =]

Why not just port your 15? it will be louder than a 12 ported. but a 12 sealed with punch harder and tigher bass

also depends on wat sort of tunes he listens to and if he wants to go for SQ or Streetbass. =]

listening to music and going for SPL are 2 totally different worlds, listen to luke, he knows what hes talking about

stu, im sure you do to but i dont know you yet

i like sealed 12's for listening too and you can still hit decent db figures my primera used to run 144.4 with 4x 12" kicker comps in sealed boxes

ive gotta say heard of a seal box go over the 140db mark. the loudest sealed box in (((popper droppers))) tested last year was this guy:

Mamesh Varsani - 4x Hifonics 12" - Sealed Box - 2500wrms
Total Average (((Propper Droppers))) Score = 136.8dB

Peak= 138.3dB @ 42hz
40hz= 137.8dB
33hz= 136.6dB
25hz= 135.8dB
20hz= 135.5dB
