Ported Subwoofer Build Projects
What up Shackers, i just finished my first DIY sub and it is supposed to be tuned to 20 hz, my question is how can i tell if i really accomplished this? what to listen for and how to accurately test?
Oh, it's a 12" SVS sub, 3.9 cu. ft. box, 4 inch port 18.5 inches long.
