Any issues having stacked stone wall behind speakers

[Grasshopper]

Thanks for sharing that. I'm not smart enough to understand how this all works, but I can say I am happy with my Mcintosh MEN220!

As that article explains, not all room correction software are the same.

And then comes the question of what a "well treated room" means. A well treated room can mean destroying the "look" that the OP wants. It can also mean spending thousands of dollars in a room and still find out that it needs thousands of dollars more (it is a huge room after all).

I am not a proponent of trying to fix everything with room correction. The idea is to do the best you can with proper placement of your speakers and some judicious use of some treatment (e.g., that concrete floor needs a carpet) and then use roon correction to improve the sound. I have yet to see a system that cannot benefit from it.

I should note that some manufacturers that do not offer room correction in their products use the argument that room correction is bad. Perhaps it is bad only because they do not have the know how to implement it in their products.

New performance venues built today incorporate the latest in acoustics and engineering. They have well thought out room dimensions, panels hanging from ceiling that can be adjusted depending on type of music being performed, they use hand-picked building materials including for the seats. And yet, they still use electronics to adjust the final sound. That alone tells me that no matter how well designed and how much treatment you put in, you can still do better with judicious use of technology.

You and the wife might want to take a look at the two different types of freestanding absorber/diffusion panels below as they come in many different styles and colors. I am using 2' x 4' freestanding panels in two different rooms directly behind the speakers. If she will not allow them to stay in place all the time they are lightweight and easy to move so they can be put in place just when you are listening in the sweet spot. You might be able however to find a color and design that over time will just blend in.

Thank you all for the comments.

Am I correct in my assumption that I am free to have stacked stone behind my system and not have catastrophic acoustic results? (As long as I treat the first reflection points with some treatment/care)

You'll be fine.

Chances are your Earthquake Supernova will cause a stone avalanche, but as Serge said; you’ll be fine.

Avalanche!!!!

Thanks everybody.

Happy wife = happy life!

I only looked at the article quickly but from what I saw they are only talking about frequency correction and they don't mention temporal issue which as Serge mentioned are the ones you perceive the most. Only room treatment can take care of those and AFAIK no DSP can work in the time domain.

The most important value you need to have a look at in any room is the RT60. Hitting the correct number will do wonders for the sound and it costs less than a pair of cables.

That's not correct. Dirac Live corrects the time domain as well. See below...

DSP has come a long way. And Dirac is not the only one that can address time-domain issues.

BTW Mcintosh uses RoomPerfect which is a Technology developed by and licensed from Lyngdorf.

Ok AA’ers.

After some delay - we are rolling full steam on our basement.

I should have the stone up in a few weeks—/-

I’ve been considering a fixed screen (120” diameter) for the projector.

The alternative is “roll” with the retractable screen.

Obviously the roll-up screen exposed my beautiful stone and the diffusion qualities when I’m listening to 2.4 channel music.

The question is, will having a 120” diameter fixed screen on the front wall, behind the main speakers have a negative impact on the sound?

I can’t wait to unleash my Aidas in the basement - and would love a fixed screen for the improved video experience... am not keen at any upgrade that would be at the expense of 2.4 channel listening.
