40hz Posted February 28, 2007 Report Share Posted February 28, 2007 building a ported box for 1 audioque 2.5 15/similar to DD.this box will be in a blowthru in my s10 pikup.My question is where to position the port for a daily set up tuned to 40hz.My plan was to side fire the portinto a chamber that will deflect all the sound into the cab.in my past, boxes have sounded better w/port bouncing off of something.this is my first blowthru box so i was wondering if i should do the same or fire the sub and the port straight into the cab?the opening is 12x32inches.box will be 4.5 cubes total.then 64 inches of port 16 in long,tuning to 40hz.net vol.4 cuft.after diplacement.I want max sql.thanks for the help.sub will be here next week.

Dozier Posted February 28, 2007 Report Share Posted February 28, 2007 Just fire it into the cab. I am sure it will sound fine. If you are not going for pure spl and want sql. Quote www.AlabamaDrift.com04 Silverado in the works Link to comment Share on other sites More sharing options...
