Thread: Box Loudness.... Help?

Is your buddies box designed by JL for those subs? If so it is very hard to make the box better. Unless the box is poorly constructed. But assuming the enclosure is properly constructed and it is a JL designed enclosure not likely to get better. Now if the box is not properly constructed build a new one that is. If it is not a JL designed enclosure find out what JL recommends and possibly build another to their specs.

Or he can add two more woofers or double the power.

to me vented and ported means the same thing

Nic.....I missed that. Vented and ported are the same thing.

It might make a difference, just because each sub is only pushing it's own airspace. So it might make the response a little tighter. Plus it might be more efficient because you'd have two vents instead of one. But I do agree, if they're in a JL box, that'd be as perfect as you get it.

However, I don't think it will create a 'miraculous' amount of bass.

It's a generic vented box, I was under the impression that vented had no sealed anything about it, and that ported had two chambers one side of which was sealed and the other that had the ports about it?

your thinkng of bandpass which is good for spl but is usually bad for sql. It is also difficult to make because everything has to be perfect otherwise it will sound horrible. If your friend is using a generic box he should probably make his own. He will most likely get better results. Generic boxes are not tuned for the sub and they are sometimes made poorly.

lil_ace is correct...it would be best to build a JL designed vented enclosure.

typically, a monobox is a sub box that's one chamber, no matter how many subs are mounted to the box, they are a bit louder, but I don't think it's worth worrying about honnestly....

you say your friend wants louder....

sounds like he's got the subs to do what he wants, and possibly the amp.....my next place to look would be power wire....if it's not big enough then he's not getting enough juice to that amp and it's not going to be at the top of it's game....

you say 2 JL audio W3s.....what 12s?

in what vehicle? in a suburban or a hatch back?

if the box isn't to JLs specs I would definately rebuild to their specs, and build the hell outta it....i'm talking at least a single layer of 3/4" MDF, wood glue AND screws/air nails, and silicone all joints once it's all put together....

His box is in a 92 Caddilac (minds blanking on the model) 4 door with box in trunk. He has two 12" JL W3's and didn't spare any quality/money by getting the bigger amp, what size power wire should he be running? Any bigger than 4 gauge?
