Hey all, bought a 15" Q last night to mess around with and have some questions. Recommended enclosure is 2.8 to 4 cubes and tuning anywhere from 28 to 33. I need to figure out where in that range I should build.

I listen to mostly metal, rock, blues/folk and on the rare occasion I'll crank some old school hip hop. I know kick drum is front stage and I will get flamed for this but I still like cutting my subs at 80 to get some impact for kicks out of them.

I have a Kicker sx1250.1 that will be going on the Q so it will be just a bit over the rated limit of the woofer. It will be going in the back of my 07 extended cab F150. I toyed with the idea of going sealed but I know if I did I'd always wonder about the output potential of ported...so might as well just go there.

So I need to figure out what size/tuning is best for my situation as well as sub/port placement. I did sub forward port up in my s10 with a gaggle of re8's and it sounded great and got loud so leaning that way.

This setup is replacing two dd1508's so I'm sure no matter how I go about it I will be pleased in the upgrade in sound quality...they sounded like crap!

well I can't tell you much specifically as I'm hoping my box plan works for my 12" BTL. but I did find www.subwoofertools.com/forum/ported-box.asp to be very helpful in my planning. I did add on some xmax which made the port size bigger after a few suggestions from other people on here. Based on what I've been recommended I'd say go with the biggest box size and make the port just a little larger than specs recommend but that's just my 2 cents

Well, after diggin through about 12 pages it looks like almost everybody does the 4ft with either a 30 or 32hz tuning. Supposedly that nets a huge gain down low over sealed.

I'm probably going to give that a shot and see how it goes. I will probably build a sealed box just for a comparo as well. Sounds like the Q's do pretty darn good sealed too.
