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

Yeah you may need an absorption panel if your room is completely open, ie. No rug or furniture, ie just lonely single chair. But if your system can't cut it in any room then it's a system problem and you should be able to discern a good system regardless of the room.  Unless you put it on the roof of your apartment building but the Beatles seemed to have survived that effort

I think people go nuts with all this absorption acoustical room treatment stuff and it looks kind of awful.  Once in a while you see a really cool looking diffuser panel and I would definitely want one. But to have a system that works really well without any of the acoustical panel distractions is a wonderful thing.


 My belief is that you should be able to discern the quality system regardless of acoustical treatments.  The problem is it's very difficult to play around with things given the massive weight of all the equipment. Once you get everything in place it's very difficult for you to swap in and out different options and you're pretty much stuck with what you've got.

It's not rocket science, if you have an echo room get a rug, buy some furniture and maybe stick an absorption panel on one of the walls and corners. Unfortunately most people are hard-pressed to put acoustical crap on their ceilings. Getting rid of reverbs is important and size of the room is important. If you've got a very large room you're gonna need a lot of power to fill it with sound and of course speakers can handle it. Again it's not rocket science. And if you need special gear to test the environment so you can feel more confident that's a problem, you should be able to discern it all by yourself. 

One useful experiment I think audiophiles should do is to record themselves talking in a living room or kitchen or dining room.  Then listen on headphones.

What you will hear in the headphones is all the room resonances your brain is actively removing while listening.

So, taking this out of audiophile land, why treat a meeting room?  Well, because your brain actually works less on acoustic filtering and you'll feel less tired. Same for classrooms, and auditoriums.

Here’s a video that speaks to this topic.  The clap example he gives at around the eight minute mark illustrates the point well.



I definitely want to try them someday but I think how he is doing the testing should be considered. How many people stomp around on the floor while they are listening ? You can make anything vibrate if you give it a big enough shock. What does the needle do when there isn’t any sudden shocks ? I would like to see what the floor does when there is music playing. Put that needle on the floor. Again this applies to a concrete floor. And exactly how much vibration does it take to audibly change the sound ? 

@jperry Look at this as an opportunity to educate people and don't assume everyone is a longtime seasoned audiophile. If the person is just trolling and has a history of that in these forums that's a different story!
