Re: driver testing

Certainly don¡¯t disagree with your assessments.? For me, the DQ-10 was a halo product when I was a teenager.? Today, I have amps and speaker systems in excess of my needs.? Many of the speaker systems I¡¯ve built outperform Dahlquist¡¯s on every measurable metric, still the DQ-10 holds a special place in my collection.? They still get used, albeit less often some other speakers that have a more refined sound and darker backgrounds.? Their popularity today speaks to their mystic and also their overall musicality.

Having not owned 10¡¯s since the 70¡¯s and given their age, some say there are more practical options for speakers like that magnepan set for under 2k. The imaging is exceptional obviously, but one can¡¯t overlook the fact that the drivers are quite ordinary and the 10¡¯sI have heard struggle with heavier music. Add subs and power and you are getting up there in cost

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?
