It can be proven with measuring, it is not that difficult......
You really think the speaker starts at 20hz at very low volume?

Why pay so much for super high end?
bo1972You really think the speaker starts at 20hz at very low volume? Oh yes, even below 20 Hz. Well below. Yes, you can measure it. |
bo, Human ears do not hear it as such in that ear frequency response drops off at its extremes (remember loudness buttons and equalizers?) but if everything in the system needed is up to snuff to do it absolutely no doubt it does. Ears have less issues when volume is louder. So its either your ears that are hearing that or the system your are measuring otherwise is not up to snuff to do it or else your measurements are in error. |
With S.A.P.-measurement I can get a subwoofer in phase with the speaker. But it is even more than that. You can use it to a much higher frequency. The energy is so much more perceivable. I auditoned many big speakers in my life, when you play at low volume you miss the realism in the low frequencies. That is why they often play loud. With a subwoofer with S.A.P. you go to u much higher level of realism. The energy of a double bass is not only what becomes fully free from the speakers. It is of each string you can feel the energy. This level we never auditioned even with sets of over 500.000 euro. It is not about the money. It is being created by accuracy and timing. My Pl-500 starts at 22hz, but with a PLW-15 (16hz) with S.A.P.-measurment you go to a different level and league in sound realism. When I listen full range to my Pl-500 (8ohm) and my Pass (700 watts by 8ohm) you never will reach the level in realism in the lowest octaves. Especially at low freq. These days I seldom sell stereo without a subwoofer with S.A.P. By using professional lasers and working at 0.5mm precision you reach a new level in timing and integration. Even in height the energy differs a lot more. The stunning part of the Pl-500 is the diversity in the whole frequency. We compared it with the Wilson Audio Sasha. It was not a match, it outperforms it in each part. I hope to arrange blind shootouts in 2017 with many highend loudspeakers. Audio is all about shootout and may the best win. When you listen your beloved music and instruments are played at the right height it brings you into another league. This league was not there with the Sasha. With the other Wilson Audio demos showed us the same level of diversity in height. It was very limited. We have plans of giving demos using a big curtain. And also using conservatory students. The reason is that in real I can let people hear diversity and intimate focus of an instrument and voice. In the last 6 months I have done a lot of research in diversity in sound. Now I can create a much higher level of diversity in the whole frequency response. Beside this we can create a stunning level in intimate sound with the best blacklevel you ever auditioned. |
" Human ears do not hear it as such in that ear frequency response drops off at its extremes (remember loudness buttons and equalizers?) but if everything in the system needed is up to snuff to do it absolutely no doubt it does." I'm not sure what you mean by up to snuff. Are you fixing the roll off at the extremes with some type of processing? If so, it seems like the system would have to be adjusted for each person. |
