As the latest firmware (rev. 2.00 Jun 08 2021) brought a composite PRIR builder application, I’ve extracted 15 virtual speakers from my previously measured PRIRs that were stored in the A16’s internal directory and created a new 9.0.6 channel PRIR file consisting of L, R, C, Lw, Rw, Lss, Rss, Lb, Rb, Ltf, Rtf, Ltm, Rtm, Ltr and Rtr speakers.
The virtual speakers were generated by measuring a system consisting of two KEF R3 speakers, stereo amplifier, SVS-2000 subwoofer and miniDSP DDRC-24 device for room correction with subwoofer integration (high pass and low pass crossover filters set to 80 Hz). The PRIR measurements were carried out in line with the proposed procedure of
@audiohobbit.
There is no virtual subwoofer in my composite PRIR file because I suspect that something went wrong during the separate PRIR measurement of my subwoofer and that adversely affected the sound in the listening room. A PRIR for a virtual subwoofer can be taken from the factory PRIRs inside the Realiser A16.
Prior to building the new composite PRIR, I enabled denoise for each virtual speaker and changed azimuth angles (Azi) for Lb and Rb speakers.
In November 2020, when I shared my PRIR files, there were complaints of higher level of distortion heard. To avoid damages to other people, I took down the folder with my PRIRs.
Now, I’d like to share the resulted composite PRIR file that can be used for building a Dolby Atmos listening room. As the composite file has no PRIR of my subwoofer included, I think that there will be no more distortions. Anyhow, start listening with the volume at a lower setting and on low gain.
I've uploaded my composite PRIR file to

Please write back here about your experience with my composite PRIR. Also, don’t forget that most probably you’ll need to use the manLOUD method of the A16 to adjust my composite PRIR and use your own personal HPEQ of your headphones.
