*****n old timers!.. and I'm 50...lol... I tuned as low as I dared... it's just under 30 hz tuned and that's my limit... don't want to lose power handling or too much output... but it's a decaf tune... some of us listen to that crap!.. my da*n Skars played 22hz well in the extended ported box I had... but output WAS affected too much... I do agree up to a point... there is a happy medium in there somewhere... it's at about 30hzTuning under about 32 is pointless and you loose a ton of output
