Hello all,

I'm currently messing around with my HT sub and messing around with the port...now here's what i dont understand, if i add another port and entered in win isd alpha, it says i need to double the length but it doesnt specify if each port need to be doubled in length or i divide the length to the two ports. example if it says 20", is it 20" each port or 10" each for a total of 20"?
I hope i'm making myself clear,lol. any help would be appreciated.
TIA

    Anyone understand just what port length controls. When I built my sub Tom, I think that was his name, at Svs told me what size port to use but I didn't bother him with questions about why. I don't mean to be a highjacker here, but it looked like your question was answerd.
