JBL Joe,
This is what I was trying to explain,
JBL had excellent tools in the form of the best audio testing equipment,
like Aerobic Chambers, scopes, Spectrum and Distortion Analyzers,
and multi function generators, as well as sound engineering and the right attitude.
But back then, the supply of multi function generators
that could supply ULF/Htz was expensive (Hewlett Packard...) and limited.
But Sansui just happen to have real/proven
DC Amps and Receivers that could and would happily
reproduce Sine and DC/Square waves from +.0~ hertz to 100,000Htz
and beyond,
this over and above ultra flat spectrum at song with low distortion sound/sine or square wave.
Back in the 70's, if you were a big highest quality audio component manufacturer
and you can buy another Hewlett Packard Generator for $$$$
or you could talk to somebody who already made DC amps capable
and proven to be flat from.0~ to 100,000Htz,
wouldn't a working relationship be sound advise?
====================================
-Somebody already mentioned that the AU line was capable of ~0 to 400,000 Htz at Voltage/watt.
-In 1980, While my Brother was attracted to Big Goldish Marantz Amps with Oscilloscopes built in,
I was attracted to 0-80,000 +/- 3db at rated output both channels driven
with no more than .02% distortion + much headroom driving 4 17 inch kabookie woofers
that were/are still capable of sending low frequencies to my core
so much so that my heart felt like it was having a hard time "thumping" to it's own beat,
And I Liked It.
?
?Hey, Wait a minute,
Now that I Come to think of it,
Maybe that was that was my Harmon Cardboard?
cordial,
moe
