Shelf braces in themselves have no effect on standing waves. They are there to make the panels more rigid, nothing more. A damper is something used that presents a resistance to motion, like the shock absorber does for a car. Shock absorbers prevenet the car's springs from bouncing violently with the weight of the car, and they damp the vibration to one or two cycles.This is exactly what sound absorbent material does inside a speaker cabinet too. It damps unwanted resonances that setup inside the cabinet. If the absorbent material isn't put in the right place, it doesn't do any good. It would be like putting the shock absorber in the trunk. Lining the sides of the cabinet with thick insulation does a good job of absorbing sound in the upper midrange, but it doesn't do anythung at lower midrange and midbass frequencies. Basically, the thickness sets the lowest frequency where damping is effective. If damping is required at a lower frequency, space the insulation material away from the cabinet walls, where it can absorb energy effectively in the frequency range required.
