When the excess is removed from the setup, the process becomes easier :).
I decided to share the latest updates, because among the subscribers there are a bit of audiophiles and people who appreciate good sound and listening environment. So this post is not only about "pro" audio, the info can also be useful for those who like to listen to music in their living rooms for example, which means floor or table speakers 6-8 inches (without a subwoofer).
So recently I changed the desktop - now it's really small)) and minimally affects the sound in the room. The monitor stands were also replaced and the previous diffusers turned out to be no longer suitable (I will write a post about why I decided to move more towards diffusers rather than absorbers for my room). Actually, both the previous and the current solution are extremely primitive, but in my not ideal room this simple method also works very noticeably, namely two chipboard boards located at an angle (it’s worth experimenting on your own here) near the back wall behind the speakers, the effect is especially noticeable on phase inverter audio systems.
If you try to express the meaning in a nutshell, then physics dominates here, diffusers are designed not to absorb excess energy from the phase inverter, but to dissipate, and this is not bad idea if your room is not too small. Playing with the balance of dispersion and absorption allows you to become a master in the field of listening to music in different acoustic conditions. Once you have mastered this art, you will always be able to provide an acceptable listening environment in any more or less tolerable circumstances.
My 22 year old unbiased nephew participated in my last test)). He is impartial, listens to music in different genres, is not an audio engineer. I put him at the listening point, turned on the Mark Heaney album - there is a fairly clear, dense and distinct picture in the lower spectrum. While my nephew was listening to the same track in a circle, I walked between the monitors and either put or removed my non-tricky diffusers, let me remind you that they stand at a certain angle due to the best, purely physical dispersion parameters. Then we switched places.
What we heard is that the bass is of course less reflected off the surfaces and becomes more collected and focused, it does not become less (once again, this is not absorption), but the picture below acquires significantly better detail and overall bass composure, without ambition to audio surgery. But with enough listening experience and confidence in your abilities, it's enough to significantly improve the acoustic conditions in your living room or studio, which can require a number of compromises. My new diffusers are much higher than the previous ones, as a result of which the angle of inclination is less sharp than before, which did not critically affect the reproduction and taming of the remnants of fluttering bass. I will continue small experiments that make life easier not only for us, audio engineers, but also for connoisseurs of music and a good reproducing system. All the best, I will be happy to answer any clarifying questions. I wish you all more good music and enjoyment from it. 🎶🎧
