Cardas Speaker placement..

It's not the amount of bass it's the lack of..I don't know if I over did it with treatments.In the corners I use the LENRD bass traps In the corners on the walls i'm using some DIY panels I made from 3" 705 rigid fiber glass framed in wood.The tops of the panels are covered with uralex metro foam..the system sounds very lean or thin in bass.No matter where I put the speakers ,no matter where I put my chair it sounds lean .Once again I tried other speakers with the same result..Only when I walk behind the speaker plane does the bass comes to life.

Stanwal, It's a delicate balance. Did you get an increase in bass or a decrease in higher frequencies?

Without treatment the reflections reinforce some of the higher frequencies and cancels others. Makes the sound seem "louder" but when you listen carefully there are things that just aren't there that you hear with treatment. I occasionally take everything but the corner ones out just to check; I leave them in as they are screwed in, the others just hanging. With the treatment music sounds "softer" but there is actually more treble if anything; just a lot more even in character. There is definitely more bass with the panels; get a lot of cancelation without them. In a smaller room reflections are a much bigger problem than in a larger one.

speakers out of phase?

again I am grasping at straws here...

Interesting to run into this post. I'm in the same boat. Just moved into a new room and am trying to figure out where to place my speakers. I too tried the Cardas Placement calculation and actually liked the result only after adding diffusion at the first reflection point. Since our rooms are similar in size (14' W x 21' L x 8' H) the Cardas method put my speakers 4' from the side walls like yours.

I could not get the bass that I was looking for and the speakers actually seemed to almost be out of phase. I kept rechecking my cables and would swear that the speakers were out of phase. Talking to another audio buddy of mine he explained that the sound was arriving to my ears a bit too quickly thus canceling out some of the sound and giving me the phase sound. I added a 2 x 4 absorption panel and the bass began to appear. The sound was actually pretty good but I couldn't get over having the speakers so close together plus it seemed like I was sitting right up against the speakers.

Wanted to try the 1/3 placement calculation to see if there might be an improvement. This would put my speakers 27" from the side wall. This sounded a bit better to me but I felt the speakers were a bit too far apart now. I kept inching them closer together and now I'm about 36" from the side wall and I'm getting good imaging and the bass is sounding pretty decent. I can't say that this is the final resting spot but I have the Cardas placement taped off so I can return the speakers to that spot if I choose to.

Go to the Evolution Acoustic Website and see what they suggest.

I'll keep you posted on any improvements or new developments on speaker placement.
