Manifold Design on HornResp

[arnoldno3]

Hello,

I am looking to try and design a dual 21" manifold subwoofer similar to the 18 Sound double 21 IPAL subwoofer but I am struggling with the simming on HornResp, is there anyone here who can help guide me through designing a subwoofer like this on HornResp?

Thanks.

Looks pretty straightforward.

Offset driver alignment. S1=S2=S3=2520cm^2
The rear chamber is a simple ported box.
