Marvel,
Hey - thanks! To be honest, I only saw the sectional rendering, so I did not know that this was a retrofit to the mid/tweeter section. I assumed that what you drew would be a mod for the bottom of the cabinet, and since I'm doing mine from scratch on Soildworks, I've already modeled it as and extension of the bottom with the ports facing forward. I'll give it a spin and keep you posted.
Thanks,
Mike
