I just figured out that my box is tuned to 40hz.........not 30hz.....and my sub-son is set to 25hz. but my sub hasn't ever unloaded.....only once when i was playing some Chopped and Screwed music with the Sub-son off.....hmmmmm
the guy who built my box said he tuned it to 30 hz....and that he tunes all of his DD boxes to 30 hz.....but i went on their website and i figured out that my box is roughly 1.5cuft. after port volume and such and then their port recommendations almost matched mine....theirs said 22.something inches of port area....i have 21" and their port lentgh is 16"....so is mine...and it says that those dimensions tune the box to 40hz.
I also went onto some port calculator sites and put my info in and in order to get a 30 hz tuned box my port length would have to be like 31 inches, but if i put in to tune it to 40 hz.....it calculates the port length to 16 inches......
i hate having to find sh1t out the hard way.....but i don't understand my sub still gets low.......
hmm, alot of people make that mistake muddy!! but your box is tuned PERFECT for a DD!! 40hz is the sweet spot! Leave it @ 40 man!! Treo recomends DD tuning... and my new box will be 40hz!! People dont realize 40hz gets crazy low!!
i am just pissed b/c i at one point in time thought i had a 1000 series DD....then when i got my new bass amp and had to take out the sub to rewire with bigger wires i founf ou tit was a 2500.
then i was told tha my box was tuned to 30 hz...and i just found out that it was tuned to 40 hz.
but my sub hasn't ever unloaded.....only once when i was playing some Chopped and Screwed music with the Sub-son off.....hmmmmm
