If you have a nice system why do you really need room treatments?

Okay. I'll give this a shot:

As long as our ears are still analog, we'll need to deliver music via mechanical means.  These changes in sound pressure, essential for the reproduction of music, are projected into a space and interact with anything and everything they come in contact with.  These objects create additional in and out of phase signals (coloration) and refraction/reflection (blurring) and other artifacts.  A quick demonstration of basic acoustic principals could involve: 1) speaking normally, then 2) cupping your hands around your mouth and speaking the same information.  A more advanced and room specific demonstration would be to position yourself in the center of the room and speak normally.  Then, position yourself next to a wall and repeat.  And perceived differences would demonstrate how "the room" is affecting the sound.

Helpful?

I've never had the need or felt the desire to have a dedicated listening room. After reading this post, I'm happy for myself!

There is something out there that will get rid of almost all room problems, It's called the Townshend podiums they isolate vibration down to three Hertz, as soon as I put them underneath my speakers all that thumpy bass that was going into the floor disappeared and same with the side walls and the improvement was as if I had upgraded to much more expensive electronics they're not cheap but a lot cheaper than putting up room treatments and making your room look god-awful.

@Emergingsoul, I am sorry to hear about your condition. That said, you could publish details of your system in a post on this thread. I’m sure it will require a word count less than many of your posts.

As regards the substance of your post, acoustic treatment can take many forms that do not require the use of dedicated treatment devices. But those devices, used appropriately do have an important role to play. I’ve come across many instances of people with expensive systems placed in bad sounding rooms, where their investment in equipment was effectively wasted and where a much more modest system combined with correct room treatment would have sounded better for less expenditure overall.

The room doesn‘t have to look awful.  Corner traps and diffusers come in some artistic looking designs.  Balance is the key.  Too much and the music will sound lifeless.  Furniture also makes for good absorbers.  And the room looks less lonely than a single chair in the center.
