This is the "soon-to-be-mech-engineer" side of me coming out. Lying in a half-asleep state this morning, these thoughts came to me.
According to all I've read about speaker design, the ideal is to have a non-resonating enclosure, which explains the popularity of MDF as an enclosure material. The fact that it's cheap probably doesn't hurt.
Now, when it comes to cross-bracing inside the enclosure, I have yet to see any rhyme or reason other than "try to make it non-resonant." This answer has never really satisfied me, so I began to wonder what rhyme or reason might apply to this problem.
You know how similar vibrations that are out of phase with each other tend to cancel? Perhaps the box could be designed in such a way where the cross-bracing mechanically linked areas of the enclosure that are out of phase with each other, thus providing a nice, non-resonant enclosure.
Calculating these point would be a trick, and is something I don't know how to do (yet). I also think that how you do the crossbracing would depend on the crossover you choose, since the phase of the signals coming in can change depending on the crossover design, or at least that is what I've divined from all I've read. I could be wrong.
It also seems to me that the placement of the drivers on the front would also have a bearing on where you would want to place such crossbracing. This kind of design would definitely need some thorough planning out.
I also seriously doubt I'm the first to think of this.
So, is my thinking any good?
Thanks, all!
