well the sansui sp-x9900 lack bass at low volume but when u turn the volume up the bass is strong and tight Not a bad sounding speaker a little bright in the mid and hi freq range but other than that the speaker sound nice. they r not my jbl 4345 but I will say they sound better than a lot of speaker on the market today for a 30 year old speakers the only thing I will change is the caps in xovers
