My converted one of my rooms in to a studio/band room. but i'm having trouble with the way it treats some notes, estentially the E.

I thought it was just the guitar amp, but playing the piano thou reason and computer I notice the same crappy E. Put head phones on and it sound great.

Here is a diagram of my studio.



the JBL EON is on the other courner now. And i have near field monitors on each side of the computer monitor.

the demision of the room are LxWxH - 15'3" x 10' x 7' 9"

the height is approx.

But the e sucks, any ideas?

"E" has a fundamental of 40, 80, or 160 Hz depending on the octave. The lowest three are above. "A" has a fundamental of app. 60, 120, and 240 in the same octaves. Do note a similar problem with A in any of the above octaves?

The ceiling height implies a mode around 75 Hz. Is the lousiness consistent as you move around the room and/or move the speakers?

How is note lousy? Lf absorption comes to mind if it isn't location related.

Beethoven's fifth must be terrilble in that situation.

Its the high E on the guitar, and the E below the middle C I believe on keyboard.

I do not really have a choice on moving speakers around the room. Only option i got is to try the piano on my PA speaker and see what i get. Which I will try later. But the E sounds very dead, has a like really bad reverb sound to it. the D and F around it is smooth, and the E has like a harsh high sound to it, instead of ringing out smoothly.

One thing i need to meantion is the door is just a open space that leads to a hallway thats about 3 to 4' wide I persume. Should I make a temporary door/cover for the open gap thats about 4' wide.


Also I like to say if you just play the guitar with out the amp that terrible E sounding is still there, even with an acoustic guitar.

Is there a calculator to find out which standing waves there are in my room?

Right a the top there is sticky to a room mode calculator. It is an Excel spreadsheet.

do you mean the top string (highest pitch)?

If so, it sounds like problems tying in with the note with a 160 Hz fundamental.

those links seems for near field monitors which is different.
