hi its me again, i currently have a bl15 great sub, Ive seen people seem to like more the 18 inch subs better than 15" are 18 that much better, i see they need a big box but would the output be that much better if yes what percentage increase do you guys think i can get with a 18". Now my other question how can i make a box for one that is going to be in my caddy devilles trunk i cant go higher than 19 inches tall for the box and i dont think i would make it becuase the sub is 18" plus box material .75, so can i make a box facing up and port facing to the back of the trunk?? would that sound good in a car?? thanks again and comments are apreciated.

Not a fan of up firing in most trunks. 19" of height is fine provided you use a full 19" of height for the front mounting panel. This will give you more than enough meat for things to screw into.

In all honesty we have been selling more 18s than anything else recently. People are stepping things up bigtime. Kind of put me out for a little bit as I have been ordering cones and 18" parts based off of previous companies sales... which left me close to out of parts a couple of times. Now I over order on them just to be sure And to think I use puny 10s and 12s...lol

Looking at 2-3 dB increase across the board with the same power an proper enclosure. Nothing major, and primarily at the expense of trunk space.

Thanks,

Scott

so is 2-3 db increase a big difference?? is it worth changing my fully loaded fi bl15 for a fully loaded fibl18?? whats everyone here thinks. thanks scott.

I've got 2 x BL 18's with all the options, love em....go with the 18, 18's look way more badass anyway
