I never hear piezo unless I take speaker leads from amp directly and touch it to sprJrr leads?
Yes, sort of.? The piezo driver is reported to be difficult to hear for most people.? My 65 yr. old ears definitely don¡¯t hear it.? Otherwise, yes.? I recommend that each driver be driven individually with a tone in the center of their operating range.? Otherwise, you may get a response from multiple drivers that operate at a given frequency.? Just be careful not to overdrive an individual speaker, or you may be replacing one that worked before the tone test.

Oops, just saw Richards response below.? What Richard said.

Absolutely. And if u want to test ranges... disconnect speaker wires and hook up one at a time and run the freq individually with a dn meter at each freq, or just run a sweep.?

Ed - Can one just use the Binks test tones to merely determine that all five drivers are working?
