Huh? Why would I report your posts, Costco? They are often the high point of my day. My substitute for the funny papers, if you will.

Of course it’s only fair to point out that phase coherence is a different animal than Absolute Polarity. |

As usual, you’re pretty much wrong. Vacuums don’t exist anywhere in the known universe.
>>>>What a knucklehead. I stated that a vacuum is defined by the number air molecules per unit volume. A perfect vacuum is defined as the absence of any molecules in a given volume. There are degrees of vacuums, that’s why vacuums can be measured and there are units of measurement. Obviously some vacuums are better than others. Why do you often give the impression one exists between your ears? |
I’m afraid you’ll have to ask the cable manufacturer. I have a feeling you won’t like the answer.

Costco, when speakers are “out of phase” I.e., the + - wires are reversed on both speakers, the system is in the Reverse Absolute Polarity from whatever state it was in previously. Polarity is relative. That’s kind of the whole point. And in that sense, as on the test track on the XLO Test CD, “out of phase” is equivalent to Absolute Polarity.
I suspect this is just a simple case of you following the wrong ...you know...🐑 🐑 🐑 |
Decompress is not the same as evacuate. There can be no vacuum without an enclosure. There can be compression and decompression in a room obviously, for acoustic waves, but not a vacuum. In space no one can hear you scream.

Look, first establish whether your system is in correct Polarity or reverse Polarity using a Test CD such as XLO Test CD. Then you have a baseline. Otherwise, you’re just shooting blanks in the dark.
As I pointed out previously, it actually doesn’t matter whether your systemis in correct or reverse Polarity since at least half of CDs are in reverse Polarity anyway. If the percentage is much higher than 50% then wouldn’t it make more sense to place your system in reverse Polarity to begin with? Obviously, if you have a Polarity switch you can determine the best sounding position of the switch on the fly. But unless you have established whether your system is correct or reverse Polarity you won’t know whether the CD you’re playing is correct or reverse. Follow?
Oh, incidentally, the out of phase track on the XLO Test CD is the same track for determining the absolute best speaker locations in the room. The best stereo image is obtained when the sound is in correct Polarity after you have found the precise speaker locations that produce the most diffuse sound using the out of phase track on the XLO Test CD or any test CD that has a similar track.
|
No offense, Costco, but I’m filing your post under Whatever.
|
Even if what you say is true, which I actually doubt, it would not change the fact that at least 50% of CDs are mastered in reverse Polarity. SETs don’t magically counteract Polarity. There is no balm in Gilead. Not to mention the fact a lot of people don’t like the sound of SETs.

Hey, I’m going to clunk your heads together. You do not (rpt not) obtain a vacuum by compressing air. You suck the air out of the container to produce a vacuum. A vacuum is measured by no. of air molecules per unit volume. A perfect vacuum would have no (as in zero) molecules at all. Obviously, a tremendous mass will compress air a lot but not (rpt not) completely, which is why air shock absorbers work even for very massive commercial jetliners. PV equals RT. The number of gas molecules in the container remains constant. Hardly a vacuum. In fact there are MORE molecules per unit volume when the air is compressed. A lot more.
|
Costco is close but no cigar. For starters air shocks in cars compress as much as they decompress. Air is a compressible fluid. Pressure, volume, temperature, whatever. Hel-loo! Second, when the system is in Reverse Polarity the speaker drivers move OUT when they should be moving back IN and visa Versace. They are 180 degrees out of phase. Follow?
Cleedsy, old bean, a vacuum is created by evacuating air from the system not by compressing it. Hel-loo! |
Another excellent knee jerk reaction by the poster boy of knee jerk reactions. It’s not necessarily the recording engineer’s fault. It could the the mastering engineer. In any case there are no standards for Polarity. Any more than there are standards for dynamic range compression, another big fault that’s not the fault of the recording engineer. If you can’t hear Polarity, which in your case I imagine is true, then you shouldn’t worry about it.
|
Atmasphere, after listening to your explanation I’m even more inclined to believe G Louis. Two microphones or one, doesn’t matter, or three microphones. I also believe him when he states most audiophile recordings, even such famous ones as Mercury Living Presence and RCA Living Stereo, are in Reverse Polarity. You can squawk all you like.
|
atmasphere, you should agree with me more often. You’ll be much better off in the long run. 🏃
To be a little picky, I have been saying for CDs the percentage might be much higher than 50%. In fact, if you believe G Louis, the Polarity Pundit, the percetage is 92%. That’s why I’ve pointed out a number of times recently, i.e., the last few years, putting one’s system in Reverse Absolute Polarity might actually be the best long term strategy. What with overly aggressive compression and the absolute Polarity issue CDs have devolved from perfect sound forever to perfectly atrocious.

From the intro to The Wood Effect (1988) by Clark Johnsen, audio journalist at large,
Newcomers to Polarity do deserve some introduction though, which for the sake of everyone else I shall make brief. The abstract to The Wood Effect (1988) still explains it best:
Masked by random combination with other distortions in the music reproduction chain, an unsuspected major contributor has lain hidden: Aural sensitivity to "phase inversion", the Wood effect.
Musical instruments normally create compression waves in their attack transients. Electronics, however, often invert that natural, positive polarity to negative, unnatural rarefaction as emitted from loudspeakers, thus diminishing physical and aesthetic impact. The term Absolute Polarity uniquely describes the correct arrival to the ear of acoustic wavefronts from loudspeakers, with respect to actual musical instruments.
Wrong polarity, when isolated, is obvious to almost everyone. Its present neglect results primarily from habitual disregard for linear phase response in loudspeakers, due largely to the erroneous auditory theory of Helmholtz.

I imagine it’s because you work cheap. |
Got some bad news, Wolfie. You is officially deaf. Is it too late to request a full refund from your trade school?
|
Wolfie, your response is somewhat indicative of a two-year trade school education.
|
Having the system in reverse Polarity can be a blessing if you play CDs since at least half of all CDs are in reverse Polarity, at least according to the Polarity Pundit, maybe a lot more than 50%. There are no standards for Polarity.
