Multiple subs vs. Room treatments
 
Hi All, finally settled in the new house and working with a smaller room but still good size. I have two very good subs and all the bits to build two more. I know I have a standing wave at around 250hz so I plan on making good panels with OC703. Most likely 12 of them 2' x 4' x 3".

So I have this thought that I want to explore. I want to go with multiple subs to smooth out the nulls and peaks, BUT.....won't panels do that by absorbing the sound waves???

I can't seem to think this one through.

Hi,

True, 250Hz is a very unlikely single problem.

rgds, sreten.

The one inch 703 panels won't do much below 500 Hz, the 2 inch absorbs some more down to 250 Hz, leaving a dead high end and little LF absorption, which may sound "dead/boingy".

At any rate, the panels will do little in the "sub" 125 Hz range, so don't let them stop you from adding multiple subs.

Yea, the answer is "yes"

The only bass absorber I have that worked was a stack of FG roles in the corner. Very low WAF. Looking into panel traps instead.

The OC703 I will use is 3" thick

How does the 3" compare with the 2" in sound absorption below 250 Hz?

Don't know. Using phone so not much data

Hi,

Don't get the room to "dead".

Another reference: http://www.bobgolds.com/AbsorptionCoefficients.htm

I'm attaching the data on OC70x panels.

I've had much better success with multiple subs than absorbers... easier on the eyes as well.

Placement is the key.
