2 American Bass XD 10's box help

[bsneon98]

Hey guys I'm starting to think that I'm tired of this prefab box I got when I bought my subs. I've built smaller boxes before but none that actually involved any tuning or any real calculating. The space I have to work with is roughly

14 inches high

18+ inches deep (can go up to 24)

30 inches wide

Its for 2 American Bass XD 10's (see build log for current setup)

The box will first be tested firing the trunk lid, then flipped around to see if that sounds better. I really want those lows

Any help is appreciated as this is my first real box build.

Thanks in advance!

I've been playing with it a little bit now, and with those measurements I can get a tuning frequency of 24hz... lulz. Does that seem accurate?

Something is wrong, port area per foot is too small. IDK if that calc is the same as the old one but if you plug anything into the round port it cancels out the other one. A single 3" port isn't enough for 2 10's. Here's something I came up with, note I'm not a pro at this just trying to help out.

Thanks man, I see what I did there with the ports... stupid mistake lol.

I don't think that there's any differences but a few questions.

How is the port length 37 when the box is only 20 deep, and how did you calculate the woofer displacement?

Also in woofer displacement you have 2. The calc thinks you mean 2 cu ft. Displacement of each sub is probably somewhere between .1 and .15. I'm not 100% on what it actually is.

Here is another suggestion:

Enclosure Specifications:

Fb = 32 Hz

Vb = 2.4 ft^3

External Height = 14 in

External Width = 28.5 in

External Depth = 18 in

Port Width = 2 3/8 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

2x Front = 13 1/16 x 12 1/2

Back = 28 1/2 x 12 1/2

Left & Right Sides: 16 1/2 x 12 1/2

Top & Bottom = 28 1/2 x 18

Shared Port Internal Assembly Parts:

2 x Front to Back = 15 5/16 x 12 1/2

2 x Extension = 8 3/16 x 12 1/2

You would have to make an L shape port, and you measure down the middle like this. 17.75"+19.25"=37" For woofer displacement I guesstimated, like mentioned earlier is usually around .1-.15 per 10"

wow guys thanks for all the responses!

This design is gorgeous!

Last time I had my subs out of my current box, I noticed that each woofer has its own chamber. Any reasons behind that and if so what are the differences?

Ok, thank you! Makes perfect sense now

There are a few reasons to use this design: a) it is self bracing b ) since is symmetrical both subs loading is the same c) in the case an L port is obstructed by lateral car bracing the port in the middle can help. Just another option for you to keep in mind.
