[noser7]

Heys guys I have a couple question. I'm getting around to designing my box I juwt need any tips you guys can throw my way it would be very appreciated.

So far my dimension are 48"w 15"h 50"L.

I plan on doing double .75 wood everywhere except the bottom board. I want to tune around 40hz? I want a 1.5 sealed each to 6 ported. Also, side port or center port?

Also subs are dual 2 ohm

1 sub is fresh recone with zv3 surrounds the other needs recone, 1 coil is blown price to recone is 145. Planning on running an SS xxx 6500

The BTLs were not too suitable for 4th order if I remember right, also you are doing a different restore job to each driver so who knows what the outcome is going to be when you put all that stuff together.

No bro the recone I am going to get will be exactly like the other one. It's from corey Dean spl

Tell the guy doing the recone job to give you t/s parameters of what he is delivering, once you have them you can decide what box type is going to work for those drivers.

Yea that sounds good but I just wanted to build this box and later switch subs or more power

Bandpass boxes are not generic enclosures that work with everything. You need to design and build the box for the specific subs you will be using.

If you want a box that is more forgiving when it comes to changing subs build a ported box. It will most likely be louder anyway.
