06manvan Posted April 2, 2019 Report Share Posted April 2, 2019 I've been doing a bunch of research and some how confused myself. I have a box made at 2.6cft after subwoofer displacement. I want to do a round port but keep getting different lengths and sizes. The specs of the sub are Frequency Response: 32 - 300 Hz Sensitivity: 84.7 dB Fs: 32 Hz Re: 1.9 Ohms Qms: 6.76 Qes: 0.58 Qts: 0.53 Nref: 0.185% Cms: 0.11 mm/N Bl: 16.67 n/a Vas: 36.2 L Mms: 249.4 gr Sd: 471.4 cm² Xmax: 13.5 mm Any help would be greatly appreciated.

06manvan Posted April 3, 2019 Author Report Share Posted April 3, 2019 I'd say 33-35hz based on the little bit of knowledge I have on the subject Link to comment Share on other sites More sharing options...
bmwking Posted April 3, 2019 Report Share Posted April 3, 2019 what're the dimensions of the box you have designed? with and without port Link to comment Share on other sites More sharing options...
06manvan Posted April 3, 2019 Author Report Share Posted April 3, 2019 Its 2.6 net volume. It has a 90 degree kerfed corner that was calculated in. I keep getting a 4" port at 8" long. I'm knew to this but that seems kind of small Link to comment Share on other sites More sharing options...
