In an aspect, an ultrasonic horn includes a proximal flange, a first cylindrical portion having a first diameter and positioned distal to the proximal flange, a second cylindrical portion including a second diameter and a distal end, in which the second cylindrical portion is at a position located distal to the first cylindrical portion and in which the second diameter is smaller than the first diameter, a tapered portion disposed between the first cylindrical portion and the second cylindrical portion, and a cylindrical mass disposed about the horn at a position located between the flange and the distal end of the second cylindrical portion. In another aspect, an ultrasonic system comprising an end-bell, an ultrasonic horn as disclosed above, a transducer portion disposed between the end-bell and the ultrasonic horn, and an ultrasonic power source to supply an electrical signal to actuate the transducer portion.
