Which will be have more SPL?

[Irokpolo]

Just like the title says.

Two 15" Comps in 5 cubes sealed

vs.

One 15" Cvx in 4 cubes tuned to 34hz.

depends on vehicle but 2 15's will be louder than one cvx twice the cone area

I have a 2 door Acura, its pretty small.

I wouldn't necessarily agree. My 15L7 ported spanks the two 15" Comps I had sealed. Huge difference in sound pressure.

The cone area theory is generaly true. The more the better. But def not in this case. I properly ported CVX with 1000+ watts will stromp all over those lil Comp's and never look back.

A car's engine displacement is determined by both the bore AND the stroke. A 327 Chevy, and a 350 Chevy have the SAME bore, but...the 350 has a longer stroke. The displacement of a woofer is no different. The average 12" sub's displacement is limited by stroke. The Boston SPG555 has 3.75" of stroke. That's nealy four times the average stroke of a 12" sub, AND it fits in a 1 cft sealed box!! It takes 1000 watts continuous, and sounds AWESOME! You want some serius output? Use two of them in place of two 15's. They will fit in 2 cft of sealed space, and will weigh 52 lbs for two of them without the enclosure!!

if we were comparing ported to ported, then the cone area example would prove true.

this is not the case. 2 15 comps in a sealed box would not be louder than 1 15 cvx in a properly done ported box. IMO.

 

[Irokpolo]

Okay, lets say.

15" Cvx in ported.

vs

15" L5 in ported.

 

[btlking 10+ year member]

its all install dependant but id say the l5 do to more cone area again

 

[Irokpolo]

Lemme throw in another.

Last one.

15" Type R in ported.

yea I misread, thought he was comparing solobaric's and the cvx because they are basicaly the same woofer

ur gonna have to install and find out, go ported if ya want the thump bass and sealed if ya want the tight
