My comments:
1. You gonna give us a good shot of your Christmas socks this year or what? :bigsmile:
2. Those diffusers sure are purdy!!
3. Resonance
I had this discussion with another member here a while back and it is my current understanding that putting in braces to reduce panel size does not change the resonant frequency of the panel. Resonant frequency is determined by density and stiffness.
I have been told that resonance is described by mass spring theory. This seems to be backed up by formulas given for panel absorber design. You change the tuning of the panel not by changing the area of the front panel, but by changing the depth of the air cavity (the spring) or the thickness (or density) of the front panel (the mass).
All this leads me to wonder why cross bracing is any more effective than just increasing the thickness of the subs panels.
I'm looking forward to comments from those more knowledgeable than I on the topic.
