I see many people using products such as dynamat on the stamped baskets of the vintage MW's and I got to thinking about something.
A section of Norez in the cabinet behind the MW's is used to accomplish preventing sound waves bouncing back at the speakers cone causing it to vibrate when it shouldn't be. Does applying this section of Norez accomplish 100% of sound waves bouncing back? I'm guessing that answer is no because they are all over inside the cabinet, not just bouncing directly back and forth behind the MW. What if instead of a piece of Dynamat back there, Norez was used instead, or even both. Instead of increasing the resonance what if something that could absorb as well as increase the resonance was used? If the sound wave can be absorbed before it even hits the basket, would that not be beneficial?
