The Occasional Podcast had an interesting discussion with speaker designer Andrew Jones on speaker enclosures. I especially appreciated his mention of eliminating panel resonances by choosing sizes that would resonate at frequencies that were not in the range being produced by the drivers used. I have used this in many of the speakers I have built with great success. I'm including a photo of the inside of my truncated pyramid bases for my current speakers showing how random placement of braces breaks the panels up into many different sized sections, none of which resonate at the frequencies produced by the woofers.
One question that I have had in the past was the wisdom of soft mounting drivers to lessen the vibration of the drivers to the enclosure. That will reduce resonances of a poorly designed box, but will also change the effective mass of the basket/box combination. I don't know how that will affect the linearity of the driver working against a less rigid mount. Probably better to design and build a better box.
