View Full Version : There used to be box plans on this site....

Several years ago, there were plans for a compound bandpass enclosure for two 10" db10 subs facing each other and wired out of phase.
I built a box according to those plans but have since removed the subs.
Will any of the new 10" subs work in that enclosure? Particularly the GXR 10"?
Does anybody remember the box plans that I'm talking about?
Can the site administrators dig this out of their archives?

Do you have the sealed and vented chamber volumes available?
What is the diameter and legth of the ports for the vented chamber?

I'll have to get you that info when I get home tonight.
Thanks in advance for helping me out.

Okay, here are the numbers:
The larger compartment with the ports is 0.76 cubic feet.
It has two ports that are 3" diameter by 5.25" long each.
The smaller cmpartment is 0.54 cubic feet.
This thing put out a lot of bass but I had to remove the subs to be used elsewhere.
Any help would be greatly appreciated.
Here are a couple of options to consider...

Thanks for the help, Kim.
I'm not sure I understand the graphs properly, but it looks like any of those three subs will work fine in this enclosure.
Am I making a mistake?
Also, will putting in two subs facing each other and wired out of phase help the bass output or will I be hurting the performance of this sub?
Do you have any idea if this sub will sound musical with the GNX or just plain boomy?
Thanks fro your help.
My first choice would be the GNX104 followed by the new MOMO
MM2104. These woofers are more suited for this enclosure. It will have plenty of gain and won't require a lot of power to drive them. The response graphs are for this enclosure with only one woofer installed. I would not recommend using two woofers in a isobaric configuration with this box. The overall sound maybe leaning towards the boomy side, but you can minimize this by using some polyfill in both the sealed and vented chambers. Use the sheeted quilt lining polyfill material in the vented chamber and attach it to the interior walls by using a spray adhesive.
