I had the 20's for almost a year until I traded up to the 80's.I have never loved a speaker more than the 20's.I still think about the total disappearing act they pull.The midrange is as good as they come.The bass is real tight and and went deep enough for me.The only reason I traded up is because Im a rocker.I have a Dynaco ST-70 @ 35 wpc.I got decent volumn,but not enough for my tastes.If you can live with music instead of VOLUMN!! then this is your speaker!!
