[QUOTE="Chevyaudio, post: 6140067, member: 559770"] Ok, so worked all the math out on paper, had the box right where I wanted it, right around 5 cubes @ 36hz...So I was just messing around on the internet, and saw this RE calculator, and either that thing is crazy, or my math is off. So can someone check my math... Box is 55x16x16 That gives a gross volume around= 6.509 Port is 14.5x5x25 That gives a port area around 72.5 Displacements are=1.586 (port and subwoofer) Net volume is 4.92 Net VB=4.9 Port Area=72.5 Port Length=25 Port has no bends in it...so its straight all the way down the box I get 35.2hz anyone else get anything different? Thanks [/QUOTE]
