Maybe I should come at this from another direction. I have a 2 cuft cabinet I'm going to put an Alpha 10 into.

What port should I use?

The 1.91" diam x 1.875" port tunes a 1.375 cuft to 40 Hz with a Qe of 1.23. Should I try to get the same Qe when selecting my port?

How much volume offset should I allow for the drivers, port etc?

Thanks,
Jeff
