Anybody need 411's?

[Art J.]

Art isn't this were the 30923/30904 Attenuator's come into play ? Or required when using this combo due to the difference in efficiencies ?

Yes, the 30904 was already in line at the time I made the observations.
It may have helped to hide the situation.

My main take on the 30904 is to take the perceived shout out of the horn
due to the confined space in a home environment.
In your case you can add yours later in your speaker if you perceive that the
horn needs a bit taming down. It will depend on your room acoustics.
