All speakers have points of reflection with the walls, ceiling and surfaces around them, but it's not the primary path for the sound. Or at least that was not what I was lead to belive.

The first three sentences above are all wrong. Truly smile.

The direct sound contributes a very small amount to the speaker's transfer function compared to the reflected sound. Like..maybe 20% at the most. The early and late reflections is where it's at.

Do you think the Axiom nerds take measurements all around (some of) their speakers because they have OCD? smile

In that case you should treat the room using acoustic panels for first point reflections and behind the wall so the sound doesn't bounce back to you. I have that problem with my bare walls and it happens with every speaker I've owned. Before investing in more speakers I'm doing treatments next.

You want some sound to bounce back. Trust me. You don't want to be in an anechoic chamber when you're listening to music. Serenity_Now fixed me up real good and my 10 X 10 X 8, 2.1-channel room now sounds better than my 4800 cubic foot theatre room (at least for music). At a fraction of the cost to boot smile.

I took the statement from Mojo as a funny fact. Axiom sells speakers. Rooms reflect more sound than they absorb.

Mix the two and you get speakers that reflect sound. smile

Treating the room for stereo music only vs home theater are totally different from what everyone says. You really do not want the sound from front speakers to bounce back to you from back and side walls in home theater setup. This is why they recommend panels at ear height while seated so you don't hear the reflected sound toward you, but its fine if it goes above your head since it won't be distracting. My room is bright sounding with bare walls and hardwood flooring on concrete slab. Gonna treat them to remove echos at least. Just about every room will benefit from treatments someway or another, just some rooms require much more than others.

Wait....isn't that how Ian listen to his music....in an anechoic chamber???

Also, stereo rooms also tend to "start" with diffusion and home theaters tend to start with absorption for first (generally "most critical") improvement elements to room acoustics.

Not always, but that generalized statement is just from what I've seen, heard, read, or experienced.

Of course, a really good room has absorption, diffusion, and reflection, all at critical points that are mapped out.
