I spent part of the night reading on the benefits of having space between the speakers and the wall and the negative consequences of having the speakers too close to the wall, now I have a better grasp and I understand what you guys have been referring to, I noticed that in different articles and youtube videos the information vary about the distance and some other things, but there is a collective agreement on the main points, so forgive me if something I'm saying below is not 100% accurate, but at the end, I had to pick one source. I still going to get rid of half of the bookshelf to have a more open sound stage.
I'm using the number 33 2/5 distance from the wall based on a video I watched that suggested a distance of
85 centimeters, but even if is a little bit less or more it doesn't really change my point.
Speakers separated from the wall:
We need to keep the speakers far away from the wall (This distance varies from room to room and I have seen different suggestions), which could be at around 33 2/5 inches, to let the frequencies wave coming from every direction of the speaker be delayed by at least 5 milliseconds before is reflected back to us. Otherwise, it would be perceived by our brain as
time smearing of the direct signal, affecting the transient response and stereo imaging, it could muffle the sound where the edges of notes aren't so clearly defined, it also has an impact on the sound stage and our ability to place the instruments.
Solution for time smearing:
Believe it or not, to minimize the time smearing effect, we need to keep the speaker as close to the wall as possible which is great for my application, but this has other negative consequences.
Consequences (Room Gain):
Having the speaker very close to the wall will help us with the time smearing issue, but will boost the low frequencies (bass) up to 6db
Base on all the above information I can't separate the speakers from the wall far enough to avoid time smearing effect, because at the right distance of around 33", it would place those speakers on top of my head, anything less and I'm actually making it worst, so my best solution is what I already have right now, that is why the sound stage sounds so clear and I can notice different instruments at different positions within the sound stage. I haven't experienced yet the sound wrapping or passing behind me, but I didn't notice that even on the stores I went to, I'm hoping a better speaker in my home setting with the bigger speaker separation, may give me that.
My dilemma then is to deal with the extra reflective bass from the wall behind the speakers, and for that, I have a few solutions, that I could combine to tackle the issue.
My options to deal with room gain:
1- Buy on-wall speakers, this will deal with the extra bass.
- This will reduce my selection and therefore the quality of speakers I could choose from.
2- Create a bass trap, add Rockwool panels behind the speakers.
- According to a video I watched by an engineer working for Dynaudio, the bass absorbing trap has to be done based on measurements and not one size or thickness fits all because this could have unwanted consequences. Trying to figure this out, looks difficult, plus if I don't have to, I don't want to take away space from the small space I already have between me and the speakers by adding a thick material behind it.
3- Buying smaller speakers like the Monitor Audio Silver 50, or similar ones that have less bass, I read that the
Klipsch RP-600M is good for small spaces as well because it's low bass (Its dimension are bigger than the Sony, bringing the speakers even closer to me).

I like this idea
4- Use a mini DSP to lower the low frequencies peaks on the speakers

I like this idea
5- Seal the hole in the speaker to reduce its bass, for what I read it doesn't matter if the hole is at the front or at the back, this doesn't make the speaker less or more affected by being close to the wall.

I like this idea (but maybe is unnecessary if I use a mini DSP)
I see the light at the end of the tunnel
Any opinions?
