triple box options

[jmaratx787]

I'm pretty new to sub box building(actually I've never even tried building one). I want to make a custom box for three SPLW 15" subs. I was going to buy three individual bandpass boxes off ebay, but I would like just one box. Is this possible? Also, I would be willing to pay someone to draw up the plans for me if this is possible. Any help would be greatly appreciated.

It is very possibl to make one enclosure. 3 pre-fabbed bandpasses would **** *** though. The big question is, what kind of area do you have to work with? What is it going into? Are you looking for just SPL or SQL or just SQ?

BTW it seems that the mfg recomends 3.4 cuft tuned for each, so I hope you have at least 12 cuft of room for this if not more.

I have a 1990 cadillac brougham, so trunk space is not an issue. I don't know the difference between spl, spq, sq, etc. I just want something that's gonna make the subs hit as hard as they can. Three single boxes would probably work out better for me.

SPL= LOUD

SQL= A balance between tonal quality and LOUD

SQ= Emphasis on quality only

I don't think you are going to fit 3X 15's ported in ANY trunk.

I would go down to 2 and keep one for a spare when you blow one of them(and YOU will). You will need like 7 CU FT(net) tuned to 35hz.

Any number of individuals here can whip up a build sheet for you, at a nominal cost from the info you give them about the size of your trunk. Or since you will need a rather large box, you may need to find someone local to help you build it inside the trunk.

you want the subs to hit as HARD as possible? Then bandpass isnt the way to go. It sounds like ***, but itll get hella loud. Go with a good ported enclosure, or if youve got a lot of power, go sealed.

My 2 cents.
