10-4 on the house curve
The NRC has identified a certain curve, that most listeners like.
And NAD has implemented their own version of Audyssey, that attempts to give your speakers this NRC Curve, in your room.
NAD credits Paul S Barton with this curve, but guess where Paul got it from
That's another thing I like about the Pioneer Advanced MACCC. Even their lower end receivers have 6 MACCC Pre Sets. One can literally create 6 different room correction curves, and simply cycle through them, as you listen to different music, to see what curve sounds best, on that particular recording.
Before room correction, I once had an old Pioneer Elite Dolby Pro Logic Flagship Receiver. Now, this receiver offered many tone control memories, and once the tone control settings were programmed into memory, you could switch between any of them via remote control.
For instance, one setting might be bass control up 2, and treble down 1, or bass up 3 and treble up 2.
36 different tone control combinations were possible.
I would have to say that well over 75 percent of my records, tapes, and CD's always sounded better with some type of tone correction, then they did flat. My speakers at that time were the awesome Electro Voice Interface D's, well known for their accuracy, and near ideal dispersion.
The Interface D's were fun speakers, 100 db efficient, and -3db at 28 hz
They could generate enough acoustic power to literally remove pictures from the walls, and get the wall paneling shaking, from the pressure wave.
I was so STUPID to ever sell them
