ChevyBoy95 Posted October 26, 2013 Author Report Posted October 26, 2013 Ok, so port length is actually 22". (re did the port wall a bit to make the blue line exactly 5.75 as well. Only weird thing, have had this happen to me a lot in torres, net volumes dont match.... ever. With on paper calc I get ~15 cubes of net volume for the subwoofers. In torres im at 13. And yes, port is on 3 walls like it should, set the thickness correctly, accounted for sub displacement on both on paper calc and torres. Makes me want to get BB Pro 6 or something dependable.

Tarball Posted October 26, 2013 Report Posted October 26, 2013 SInce your blue distance is so close to your red measurement you port probably end at blue or at some unknown unknowable spot between blue and green.

Tarball Posted October 26, 2013 Report Posted October 26, 2013 I'd be more concerned about the sub closer to your port unloading.
