1: RE: Altec 604 vs Audio Note AN-E for open floorplan (0.00)
Posted by Peter Qvortrup on 2008-08-03, 04:02:22 (78.86.181.79)
Dear Doug, It really does not greatly matter how large the room you are using the speakers in if you sit 10 feet away from them, as long as they are able to generate enough sense of energy, pressure a .......

Dear Jonathan, The speakers you refer to in the post you mention are not ours and should not be mistaken as such. Sincerely, Peter Qvortrup .......

Dear Earl, So the main industry forum is pre-occupied with setting standards which are largely useless as measures of real world performance, I am surprised they have not been swallowed up by a Govern .......

Dear Duke, I recommend Don Quixote. You are assuming here that JAs measurements represent some kind of "absolute", your entire argument is based on that, has it not occurred to you that perhaps JAs me .......

Posted by Peter Qvortrup on 2006-05-21, 04:01:23 (212.42.175.73)
Dear Duke, So you are saying that "flat to 25Hz" cannot mean minus 6 dB at 17-18 Hz?? Which means they would drop by 12dB per octave, what is so problematic about that? I misread Art, but that still h .......

Dear Earl, If you go back and look at the various threads on this subject, I continually point out that we do not measure the way John Atkinson does, as it makes no sense to do so, I do the same on ou .......

Dear Duke, 25Hz at minus 6dB at 4 - 5 feet from the corner easily equals 17Hz when correctly placed in the corner, you need to read what I said properly. If you email me, I shall send an attachment wi .......

Dear Earl, Not trying to confuse at all, so I shall try again, note that we do not say that our measurements are arrived at by the same method as the one JA used, quite the contrary in fact and no-one .......

Dear Duke, Whatever JA measured was not correct, that is all I can say, I can to some extent understand why you would not believe a manufacturer's figures, but why do you choose ignore Martin Colloms .......

Dear Tom, The two-dimentionality of your entire argumentation clearly demonstrates what I said. A speaker is a pump, sure and a boiler is a kettle. Horns are not pumps they are resonators and acoustic .......
