Decades ago in the 1970s i worked for a Philadelphia area chain, Wall To Wall Sound. As a come on we advertised Dynaco A25 speakers at a price I made no Commision. We also sold the original JBL 100s and the original Heil speakers for 4 to 5 times the A25 price. It was no contest. The Dynacos were smoother, less colored and had better bass.
