Miracles in Audio, by luck, by good choices,by design or by tweaking...

What we listen to in a room are "informed waves" created by all the content and geometry of the room....There is no sound in a room that is not informed by the room, never mind the speakers....And the myth that nearfield listening gives to you permission to not treat and control the room is only that, a myth ...

The key point is creating conditions to take advantage of this content and geometry...Even taking advantage of reverberations is possible...

The main error is modifying a room in relation to only one characteristic of the sound, for example bass frequencies...

Sellers who want to profit from crowd of customer, use standardized materials and easy procedural measure on some limited aspect of the sound only... If you sell something it must be easy product and easy formula....But only your ears can speak for you about your room....It cost nothing but you must invest time....
A computer can help but no acoustical program will solve all problems... They applied formulas  after some limited feed back they dont listen to the room like ears...Then you can without even computer do the job....It takes time for sure....But this is a hobby no?

If you want to change your room the only guide is the reaction of your ears to tonal timbre instruments accuracy....Nothing else...Using only some frequencies to guide you is not the ideal path at all....

The acoustic of a small irregular room with a complex content with different acoustical properties is more complex to adjust than a Greek theater or a big musical hall...Some general rules that play their role in these bigger structure must be adjust with these particularities of the small room.... We must discover how to use these particularities or limitations in a positive way...

I create my room by listening, trying to reach timbre accuracy , the best i can, imaging, soundstage also.... The bass so important for many, come after that like a ripe fruit....

My 7 inches driver gives me a bass that is powerful and clear.... I dont think that this is commonly the case from most speakers of this small/medium size ...But in the same room 2 years ago it was not the same bass at all....

If i give to you the confidence to trust your ears, to buy less, and to play more, my goal is reached....

My best to all.....

If you can listen music at relatively low volume with a clear distinction of tonal timbre accuracy, then,
your room is very good now.....Like mine..... :)

It is not the bass frequencies nor the higher frequencies that must pilot and inform the acoustic work in a room, but ONLY the perception of tonal timbre accuracy... The conditions which you will use to improve tonal accuracy will also improve bass.... The contrary is not necessary true, because timbre tonality is more complex and encompassing concept than bass frequencies only.....Average computer algorithm for room are not made on the foundation of timbre perception.... We need ears for that....And we are lucky because we have free one.... :)

Timbre is itself very difficult to define acoustically because of the many factors playing a role in his perception....

:)

Someone said to me that I cannot have Ron Carter in my room with the speakers i own and the amplifier i also own....

This someone said that without big magnepan with very big amplifier it is impossible to have Ron Carter in my room....

But i have it, not because of my amplifier and speakers choice, they are good, but way less powerful and refined than a big magnepan with a very costly and powerful amplifier....He called my version of Ron Carter in my room, diplomatically, a "miniature"... It is not false for sure but it is not true either....Do i have a complete sound of a bass in my room? Yes....Is it on the exact same level than with the big Amp+ Magnepan.... Not so....But we speak about a low cost gear versus very costly one here.... And my point is this: i am not so far off the costly system with mine than people are willing to suppose....:)

I have Ron Carter in my Room because of the acoustic controls....

Not an electronic costly one, like the brand this person suggest, but with homemade cheap metal buckets "singing resonators" with Herkimer diamond, and my golden plates and some few others devices of my own....

The lesson learned by me is that acoustic controls is the most important of the 3 embeddings and the most transformative and upgrading feature there is in audio....

I know that most will think that i am nut.... But this is my experience....

I will not go on describing more my acoustic controls because i lack patience with peoples who instead of experiments trust only the sellers of acoustic materials orthodox view...Or people who think that bass frequencies is the thing to begin with in room control....

The analysis of sound in a room is more akin to the study of a "cellular organism" living in his own time frame (hundreth of seconds) something i call an "informed wave" than to a set of frequencies only...

Timbre is the embodiment of tonality and timbre is impossible to understand in term of frequencies only....Room controls is first and last the controls of timbre  expression.... Not bass nor higher frequencies ....But it takes very good speakers to begin with to express timbre in a perfect way for sure....But without room controls most speakers will not gives their best at all....

I will not go forward anymore....

Arguing when the world crumble is not the thing to do....

My best to all.....

These are great on top of components and shelves, and on transformers.  They come fully assembled, too.
Great value.

So these go under components to support them or loose on top?  Any idea what weight they support under a component?  I can understand the isolating effect underneath but what do they do if placed on top?
