Bill you know my thoughts about Keyboard amps compared to PA speakers..

Keyboard amps are designed for keyboards... you have a full range and no poor bass response (most PA's go down to 60}.. average keyboard amps down under 50..

As long as I still have wheels on my 70 pound keyboard amps , I will continue to use them,,

Still looking forward to a job I could use all four of mine... hasn't happened yet... two have been more than enough..
