I am just concerned my deviations from the spec sheet may have undesired effects both on the speaker and the sound it creates. With the diagram I posted above, I’m less than .2 off on net air space for the sub, and am dead on with lxwlh on the port. But around the corner, it is wider than 1.25 (although barely…). Another friend of mine suggested that I make the port an L shape instead. But then I have to re-calculate my numbers and I hate math. :doh: Thanks for the offer to stop by - but that’s a hell of a ride for me to just discuss speaker boxes. --- _[View the full topic](https://forums.speedlife.net/t/question-on-ported-subwoofer-boxes/189023)._
