dleccord Posted September 29, 2007 Author Report Posted September 29, 2007 okay so that would be .75 x 3 = 2.25" .... now if my port is 9 inches wide, do i divide that by 2 and add that to the port length of 2.25 as end factor? Quote refs: chode69, superduper

dleccord Posted October 16, 2007 Author Report Posted October 16, 2007 Hope you like not being able to play below 70Hz. thats where you're wrong. it peaks at 53hz and plays music better than most will think. Quote refs: chode69, superduper
Charger Posted October 21, 2007 Report Posted October 21, 2007 So it peaks below the port's tuning frequency? Good luck with that.

dleccord Posted October 28, 2007 Author Report Posted October 28, 2007 So it peaks below the port's tuning frequency? Good luck with that. yes it peaks below port frequency. how many cubes is the box? and what is the port width and height? i made the box with two baffles insteead, which has an internal space of 6.1 cubes before sub displacement, which is about .5 cubes. the port area was 17.5 x 8.5 and 1.5 deep from the two baffles. from winISD, my tuning "should" be around 77hz, peaking about 5hz higher than tuning frequency = low 80s, but i peaked at 53.
