@Inverse_Laplace and I will be conducting a second blind listening test. If you missed the original results you can read about the blind listening test here:

We are considering tests to attempt to answer the following questions:
The listen space will look something like this:
We will conduct the blind listening tests on 3/28/22 and 3/29/22 in the Puget Sound region.
Two primary questions for ASR members:
https://www.audiosciencereview.com/...stening-test-results-kef-jbl-revel-osd.25818/
We are considering tests to attempt to answer the following questions:
- Are speakers with good preference scores preferred over speakers with poor preference scores?
- What happens to ratings when bass is rolled off to equalize differences in bass response between speakers?
- How effective is EQ on fixing a speaker with poor tonality, but good directivity?
- ABX testing a stereo speaker pair with Dirac room correction (bass only) vs REW & PEQ correction
- ABX testing a stereo speaker pair with Dirac bass only correction vs full range correction
- Motorized turntable
- ITU R 1770 loudness instead of C weighting
- Significantly larger listening room
- Attempt to bring in more listeners that skew trained
- 5 powered bookshelf/monitors (preference ratings from 1.9 to 6.2)
- Take room measurements of each speaker at prime listening position
- 20 second clips from Harman’s list of recommended tracks
- Assistance from a statistician on experimental design and statistical tests
The listen space will look something like this:
We will conduct the blind listening tests on 3/28/22 and 3/29/22 in the Puget Sound region.
Two primary questions for ASR members:
- What other hypotheses might you want to see investigated?
- Any suggestions for ways to improve the rigor of the test?
