Hi,
I'm trying to figure out if this driver is working properly, but I have no experience with this model, and so, nothing to compare it to. All I have is a meter, my ears and eyes.
HF=7.7 LF=8.1 ohms. Date stamp is Sept.of 56. Physically this looks like new, except for a 3/16" hole punched in the treated paper surround, no doubt from a failed mounting attempt.
I have run it with both a 100 watt amp, and a 20 watt amp. I was very careful with the 100 watt, because I know it is likely more power than this speaker is rated for
It seems to sound really great when run flat at low and medium volumes, but "bottoms out" or rubs at high volumes, and sometimes med high volumes with low end kicked up, (for a split second) on peak bass notes. Again, I really don't know how much to expect from this driver,and thinking it's not fair to compare it with Pro PA drivers that I do know better.
Any info or opinions from more experienced people would be great!
Cheers.
Dan
