I can prove your room is bad


So you want to upgrade?  You want to know what the next big thing is you can do for a better sounding experience?

Try this.  Pull up a chair 2' in front of your speakers.  If you can't move the speakers, put it up to just 1, and listen for yourself.

The difference between what you hear sitting in front of the speaker like this, and what you hear at your normal location is all in the speaker dispersion and room acoustics. If you feel mesmerized, entranced, and wowed by your speaker at 2' but not 8' you really should consider improving the room, and if you can't, consider getting speakers with alternative room coupling, like ESL's, line arrays, bi-polars, etc.

That is all,

"A speaker that has controlled dispersion does basically the same thing you’d expect an acoustic panel to do, but it does a better job.”


Absolutely true.  The more controlled, the less treatment.  This is why ESL's can rock this test. 

I have umteen acoustical panels and bass traps, but until I bought a DBX Rackdrive 360, I could never get the bass balanced the way it should be.

Absolutely common.  Room tuning + EQ can be miraculous. 

If you can't have both, do what you can.

Gang, of course my post was a thought experiment.  It was meant to invoke some cheap (as in free) experimentation we could all try, and some of us could learn from.

Of course there's no one answer.  EQ, room tuning and speaker dispersion all matter and affect what we hear. :)

Hope those of you who have tried this found out something new.

Best,

Some one marked my comments about Roy Allison as offensive.

Show yourself, scoundrel.  :D :D :D

I don't. My speakers sound a lot better at the listening chair.

Which is in agreement with:
The difference between what you hear sitting in front of the speaker like this, and what you hear at your normal location is all in the speaker dispersion and room acoustics.

And based on the conditional recommendation:
If you feel mesmerized, entranced, and wowed by your speaker at 2' but not 8' you really should consider improving the room

This method does not demonstrate a need for you to improve the room.  You pass. 
@douglas_shroeder

I’m not sure your point, Doug. My post inherently allows for personal preference. Up close, do you hear a better speaker (to you) than you do sitting down.

As I think you are getting to, ESL’s are going to pass more easily here. :)
Actually its spot on.

Buddy, I was making a joke and giving Duke a platform to make the point.

ARC/DSP EQ are good tools. 

They are not better alone, nor are they as good as room treatment.  They are very complementary. For instance, it's much easier to treat room modes and nulls with than without room treatment.
Given no alternatives, you should use EQ.  Given the choice of 1, room treatment.  Given the ability to do both, do it!
I'm going to throw this discussion back at you, @audiokinesis ...


My original point was to help audiophiles figure out if the direct speaker signal was making it well enough to their seat, without tools. Your question is, literally and figuratively, orthogonal to my own. ;-)


Lets say there is a speaker with good forward and poor off-axis response.  How do you suggest an audiophile discover this with no tools but their ears?
So if the speaker’s off-axis response is poor, would you expect the room to fix it?

@audiokinesis

Oh, no, not me. :) That’s why I stated in the OP that the difference is in fact the combination of the room and speaker dispersion.


Best,

It's supposed to greatly diminish the room problems/ need for lots of treatment. We'll see.



Only for the bass. All the discussions of multiple subs eliminating a room are about room modes in the bass region.  The rest of the speaker range is still subject to the effects I noted in the original post.

Way to make audiophiles even more neurotic than they already are!


Sir, you have your hobbies and I have mine.  ;-)
