jeremyg Posted January 12, 2012 Report Share Posted January 12, 2012 based my port cut out on dimensions listed here: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=268-352 based my tuning using PSP's own calculator here: http://www.psp-inc.com/tools.html I do not know the motor diameter so I simply based the depth using the entire diameter of the cutout to insure they would actually fit. 1.8 cubic feet after all displacement is taken into account tuning is right around 37/38 HZ please double check all math to insure i didn't miss something Quote Google+ Profile Link to comment Share on other sites More sharing options...
Relyks Posted January 13, 2012 Author Report Share Posted January 13, 2012 this looks perfect if someone can take a second look and tell me if this would work well with subs and airspace id like to tune it lower tho more like 35hz if i have the room.

jeremyg Posted January 13, 2012 Report Share Posted January 13, 2012 If I remember correctly if you ran the port until it touched the back of the enclosure it would drop the tuning less then 1Hz, but if someone could double check that it would be much appreciated.

Joe X Posted January 13, 2012 Report Share Posted January 13, 2012 (edited) based my port cut out on dimensions listed here: http://www.parts-express.com/pe/showdetl.cfm?Partnumber=268-352 based my tuning using PSP's own calculator here: http://www.psp-inc.com/tools.html I do not know the motor diameter so I simply based the depth using the entire diameter of the cutout to insure they would actually fit. 1.8 cubic feet after all displacement is taken into account tuning is right around 37/38 HZ please double check all math to insure i didn't miss something According to my calculations that box specs as follows: Vb = 1.60710989 cu.ft Fb = 34.7635301 Hz Here are the details: Individual driver displacement = 0.17 cu.ft Wood thickness = 0.75 in Port Diameter = 4 in Port area = 12.566368 sq.in Port lenght = 14.5 in Port displacement = 194.144102 cu.in Total driver displacement = 587.52 cu.in External volume = 2.84505208 cu.ft Gross internal volume = 2.05946181 cu.ft The port considered is non flared type (flush mounted PVC Pipe). One other thing to consider is the clearance of the internal end of the port which is below the recommended 1 diameter minimun.
