Hey can someone design me a blowthrough. I have a 2005 Chevy colorado ext. cab and I want to put this sub in a good enough box, enough cubes because i heard they get nasty with the space. Is this hair trick capable with a single 18", 2000-2400 wrms?

lol...^ i think that was a joke.

Thanks

sub outter diameter is 18.4 i think, and then you need 1.5 above that so yeah a bit over 20 in

its a fourth order, could it not be designed with the sub facing a different direction rather than on its side?

The sub is probably taller than the cone diameter anyways. Atleast the new models, those things are deep as ****.

Yeah like pechkin said you'll need the sub to sit inbetween the bottom and top of the box so at least 20''. This is why I have 12s in my blowthrough...by bed is only like 16'' tall until I hit my bed cover. You could always run 2-15s and slant the baffles if they still don't fit...that's what I'm thinking about doing.

What is with people putting SQ speakers in bandpasses lately? Especially SQ speakers that are designed to have the flattest frequency responses out there?
