by crisp do you mean tighter bass? if so you may want to go down in size instead of up, meaning 12s instead of 18s...

yea i guess so, my boys got some w7 13" jl and they are tight and crisp. will the 18 bls be even sloppier yet?

Im sure there will be many that tell you no but IMO yes they will... I put a buddies 15 in my truck for a few days and hated it cuz it was just too boomy and, as you put it, sloppy... I love a my 12's for what I like they are perfect with just the right amount of lows but can stay tight with any music... and whos says you cant get just as loud with 12's too? hahaha

I think a smaller box would help change your sound. About any sub can sound the way you want, you just have to spend some time testing and fine tuning things

Box would also help too ^^^^

Im not dpebating anything and wont even start... Im just saying that I preffer my ported 12's to my buddies sealed 15

hahaha. He doesn't think that his buddy's 15 is ****** or his buddy's box is ****** but deduces that larger subs are sloppy and only smaller subs can play tight.

Did I say that? no I said I preffer them and was suggesting he try and listen to some 12's to see if that may be what he is looking for...

If you want tight, generally a sealed box is gonna be the easiest way to go. The downside is your gonna sacrifice output versus a ported enclosure.

You 'can' get great sq going ported - as long as it's a properly sized and tuned enclosure, but you'll need to also add a signal processor that can compensate for group delay and perhaps some eq adjustments to give a desirable response curve.

A probably bigger issue is gonna be everything in your car rattling... That's a lot of cone area, I see sound dampening in your future as well...

i just talked my friend about doin the wall of bls and he said it will sound better if i have them face up port back instead of a wall facing forward, cuz ill hear some distortion or something....

and what is the signal processor(where does it go?...in line? never heard of it)

This is bullshit. A 21 inch sub can sound just as tight as a 10 incher. Its all bout the install....Size doesn't matter, its how you use it.
