dang, thats a huuuuge bi*ch

[loismustdie]

the brahma holds the world record for loudest sub, and one of those will satisfy your needs if you set it up right.

how much does a brahma go for?

[Haibane]

About 459 for a single 15

Here you go man: http://www.acoustic-visions.com/~aco.../adire_brahma/.

I was thinking about getting one myself. Do you think one will be enough for my single cab fullsize pickup? Also, I listen to rap, hip-hop, rock, metal and techno, but 70% of the time rock. Do I want a 12" or a 15"? Also I love deep bass. Can the 12" still do that? Also, would a sealed box be the best way to go?

volume (loudness) for a sub sytem is a combination of speaker/box/vehicle. Matching the box and speaker together, and the placement of the box is critical. If you have money, seems like the brahma or 13W7 with a massive amp is the common way to go.

12 or 15 doesn't matter, it's a common misconception that the larger cone causes a drop in transient response, it's frankly not true. Same goes for deep bass, if you get a quality woofer a 12 can play just as low as any 15 or 18. If you want deep bass then a ported box tuned to around 25Hz would be a good bet. For many subs this will cause them to sound a bit boomy, but for the supersubs that you're looking at it shouldn't hurt the SQ much at all.

for deep low end, i like 15's. 15's>12>10>8>6.5>4>iono..

15's drops lower than 12's of the same model. i just like watching the bobbling heads on the dash go crazy. lol

[sr20de4evr]

Well 15's will be louder than 12's at all frequencies, and once you go subsonic it might be hard to feel the bass from a 12 anymore but you can still feel the 15. So it might seem like they go lower, but they're just louder at those low freq because of the utter dominance in cone area. Put a 15 against 2 12's of the same model and it would be a different story. The eD12A can play utterly flat down to 9Hz, if the 15A can go lower than that then I'm frightened.

[GSteg]

woofer for woofer, the 15" will always go lower than the 12" model of the same kind. speakers are mass controlled over the resonance frequency.under the resonance, its suspension controlled. increasing the mass (easiest way is to increase Mmd) will lower the Fs (hence why from Fs and up, its mass controlled) but you will lose sensitivity. but of course the extra cone area from the 15" gains back that lost. obviously a 15" has more cone area than a 12" so its assumed that the 15" has more mass on the diaphram therefore lower Fs. thats the reason why 15's go lower because of mass. thats unless the manufactor decides to use a softer suspension to bring down the Fs.

its been done lots of time to acheive that goal. a 15" will always go lower than a 12". its a misconception that a 12" will go just as low as a 15" (neglecting SPL differences). only way is to add mass, soften the suspension, or EQ the system to get the same response.

with that in mind, the 12" should have a natural roll-off sooner than the 15". thats what we refer to as "going lower" i guess. the roll-off point.

now SPL would be different obviously. like you said. 2 12's would have a much better time playing say 20hz than a single 15" due to the increased transfer function. none the less still loud as heck. lol

[Haibane]

The two big audio enthusiasts go head to head, lol. I have to say I agree wit Gsteg on the 15" going lower, most every sub I have looked at that is good, allows that their subs work that way, with more mass etc...
