I bought Neumann speakers – problem solved.
Thanks to the capacitors there is a chance for real dead silence. Maybe some smoke too.

I bought Neumann speakers – problem solved.
Sure, but it can still be interesting to hear user experiences. The hiss/noise level for active speakers varies of course between manufacturers/models.With all the modern measurement technology and instant communications of the internet and multiple first person accounts and the pooled wisdom and experience of ASR we still end up with answers ranging from "unuseable" and "defective" and "fatal flaw" to "inaudible" for what seems like a rather simple question of self noise level. I guess the old adage "The more things change the more they stay the same" is alive and well.
SPL measurements are not very useful since audibility of noise is not constant with respect to spectrum. As a result, I use my ears for noise measurements.I hope @amirm measures the actual self noise with a known distance then anybody can compare to what they have now with an SPL meter
Ok anyhow if you get a number with an spl meter its possible to compare using the same weighting etc . Not at all super exact and does not tell how audible it is .SPL measurements are not very useful since audibility of noise is not constant with respect to spectrum.

I used to own and really liked the Neumann KH120A, but unfortunately I no longer have it.@Nuyes
Did you measure the self-noise of a well-known low-noise reference speaker, like the Neumann, under the same measurement conditions today?
Yes, the differences in hiss perception were striking, even taking into account different room situations and personal sensitivities for noise.Given this situation, it actually seems quite natural that different ASR members report mixed impressions such as “the hiss is quite noticeable” versus “the hiss is audible but not really bothersome.”
Someone needs to tight the QC a little![]()
I'm talking just as me, but a 10-15% price raise for example would be worthwhile if they addressed that to a meaningful manner.Not just that. I think they need to swap for less noisy amps if these speakers are gonna cut it as nearfield monitors.
What is the actual distance to the speaker ? Is it as shown in the pictures how close in mm ? What is the noise at 1 meter then ?View attachment 517317
I was just able to obtain three additional Palmer Orbit11 units for measurement.

For an accurate comparison, I kept the microphone position fixed and simply swapped the speaker samples one by one during the measurements.

To clarify any questions regarding the self-noise measurement conditions and equipment, I am sharing a photo of my measurement environment.
I use a Larson Davis CAL250 SPL calibrator together with an Earthworks M30 microphone. On the measurement day (today, Friday, March 13, 2026), the lowest ambient noise floor at the measurement site was 22.1 dB(A).

Here I overlaid the graph of the sample I previously reviewed (measured on March 6, shown in gray) with the measurements of the three samples tested today.
Red – Sample #1
Blue – Sample #2
Green – Sample #3
I also recorded the environmental noise floor before and after the measurements, and can confirm that the measurement environment noise floor did not change in any meaningful way during the tests.
Interestingly, even among the three samples measured today, the self-noise differences are quite noticeable.

I also compared the measurements with the −20 dB PAD engaged.
(The speaker position was kept fixed, and the adjustment was made using the top control.)

This figure shows only the −20 dB PAD measurements.
Interestingly, the sample measured on March 6 shows a level similar to Sample #1.

Since these differences might potentially be related to sensitivity variations between units, I also compared far-field measurements.
If this were simply a sensitivity issue, the green sample (#3), which showed the lowest self-noise, should also have measured the lowest output level. However, that was not the case.
As a result, contrary to the initial impression based on a single unit, there appears to be a meaningful variation in self-noise between individual units.
Considering that the three samples I obtained at the same time showed up to about a 5 dB difference, it seems difficult to rule out the possibility that there may be a noticeable unit-to-unit variation in the self-noise of Palmer Orbit11 speakers distributed worldwide.
Given this situation, it actually seems quite natural that different ASR members report mixed impressions such as “the hiss is quite noticeable” versus “the hiss is audible but not really bothersome.”
The first owners subjective reviews should've made us suspicious about that. The kind of stuff that might degrade the stereo performance. Good luck with the PR.Someone needs to tight the QC a little![]()
at 0.1 m from the tweeterWhat is the actual distance to the speaker ? Is it as shown in the pictures how close in mm ? What is the noise at 1 meter then ?
