RE: rolled off at 3800Hz

"It can also be delivered accurately by
amps that are down at 80HZ, and put out almost nothing at
12 KHZ. What happens depends on the room and the trans-
ducers that are used in that room."

The amplifier is a equalizer as well as a amplifier?

"It is possible, however, to experience the delights of
a good movie theatre system in the home. If you do use
large-area transducers, you will require that either the
amplifiers or the source components are going to have to
be rolled-off."

Yes, I see. That is exactly what you said.

We should all be using speakers that do not have a flat frequency response coupled to amplifiers that also do not have a flat frequency response.

Kind of like how when a LP is made they cut the bass and boost the highs and then in the phono preamp a reverse EQ is applied to get us back to flat.

Dennis, that is just brilliant.
