    While we're at it, why have amp mfrs conspired to suppress the loudness switch? I get so angry every time I try to adjust my Yamaha AVR. Would one freakin' little switch eat into their corporate profits? Jeez.

    To answer the original question, it's 90 db at 1 meter.

      Ridikas, If you turn the volume down there will be no distortion

        Thanks, I needed that! Actually, I have a 90dB tweeter that I can crank up to eleven. It's perfect for occasions when you need just that little extra that an 88dB tweeter can't handle.

          Amps that go to eleven are hard to come by. You may need one of those amp booster doomahickys

            Same. I like a good discussion. This isn't it.

              I'll just about guarantee that if you're sitting at a normal listening distance and Fanfare for the Common Man is playing at levels you'd experience sitting in the audience at a good auditorium, those tweeters are easily generating over 90dB at 1m.

But despite numerous people with golden ears, no one can tell the difference between amplifiers---and there is no question that that measurement data is not beset by the variables in speakers.

                if you would have been at the Grand Rapids DIY event one year ago you would not believe this.

                  Or this year.

                  As far as Mr Clark's challenge, no one has one the money. But I don't believe any one has taken the challenge either.

                    Hmmm, Fanfare for the Common Man is composed for 4 french horns, 3 trumpets, 3 trombones, and 1 each of tuba, timpani, tam-tam and bass drum. The highest fundamental frequency any of those can play is 1500 Hz for a french horn and trumpet, and 1000 Hz for a trombone if it's an alto trombone. I have no idea what frequency range a tam-tam covers, however. It's true all of these instruments will have harmonic outputs at higher frequencies, but if this piece was being played where the average SPL level was 90 dB, it doesn't seem likely a tweeter would also be producing 90 dB SPL, unless the speaker in question was a 2-way with the tweeter crossed in the 1000-1500 Hz range (and such a speaker would probably have the tweeter in a wave guide where the lower end of the tweeter is reinforced by that guide so the tweeter isn't working so hard).

                      How about a bombastic high-pitched violin ( got a few recordings of those )

                        Violin goes up to 3.5 K. Organ goes up to 7 K. Piano goes up to 4.1 K. Piccolo goes up to 5 K. Play this one really loud: https://www.youtube.com/watch?v=_O3H3PU8f7M

                        or this:

                        However, if you are crossing your tweeter at 5500 hz, its only workout in direct music might be some of the highest tubes in a pipe organ, the rest is a workout in harmonics.

                          I listen from distances varying from 14' to 40', even though the SPL drop isn't as dramatic as outdoors, it of course does drop from a Meter proximity.
