My box is currently tuned to about 33Hz but i would like to have a go at Propper Droppers for a laugh and for abit of fun really .
Ideally i didnt want to make a loww tuned box just for the occasion so i thought in using a port blocker to help me drop the tuning down so i can hit the required 20Hz tone lol
can anyone share some advice in how to make a port blocker and drop it down to around 20Hz ish ?
thanks guys
