Fair enough, if that’s their thing. In my case I haven’t experienced any room issues that I’m aware of, but then I’ve never had speakers with enough low bass that could trigger booming issues so it’s never been a problem.I dont want to disagree with a gentleman...
I will only say that controls of room acoustics affect not especially the bass frequencies but all the spectrum... And people before experiencing it dont know it and are not conscious of the improper rendition of timbre, imaging and all other characteristis that are affected by the non controlled room acoustic....
I was my self completely flabbergasted by those changes because some people speak about them times to times without insisting on them...The upgrade of a room acoustic exceed easily almost any other upgrade most of the times even of the speakers often...
I wish you the best....
P.S.
Dont be afraid by those who advise to use tech program, or measuring apparus, SPL meter etc... I makes all my changes by way of fun play listening, incrementally, and step by step with the helping of my ears only... There are PASSIVE materials used for the treatment.... But way less known are ACTIVE ways like resonators, Schumann generators, Helmholtz bottles, etc; these active ways changes the look of a room tough much more so than the passive way....My wife dont like that.... But they are very powerful....I use passive and active ways...
I call the acoustical treatment an acoustical embedding of the audio system, there are 2 others embeddings the resonant-mechanical embedding and the electrical grid embedding.... These 3 treatments exceed in S.Q. change any normal upgrade not of one component, but in "some" cases the upgrade of all components, so powerful they are....
Think about any manufacturer in the obligation to reveal these inconvenient truth(for the sale pitch) to you before you bought his 10,000 dollars amplifier or dac? Will you be pleased to learn that day that his perfect engineering gear is not enough by themself to create Hi-Fi experience? Asking the question is answering it.... :)
This is my painful, unsuspected, slowly gained, experience in my journey to win S.Q. Hi-Fi by myselves because of the lack of money...
If i ever had all the money necessary, perhaps i would have never guess that truth and would have been happy with costly gear, almost used like it is out of the box with very few means on controls in these 3 embeddings dimensions.... Like most people if you look at their virtual page system... minimalistic controls if there is some....
The truth is more controls there are, better the sound will be truest to his optimal original design potential.... Most gear are good enough for us if we treat these embeddings... Upgrading is not the way half the times.... And the good news is cost may be low.... I have purchase only very low cost materials and i have reverse engineer many tweaks with ideas of my own and it was fun.... If i can make it ANYBODY can.... I am a poet not a scientist nor a solder handyman, nor very crafty hands man .... :)
