Hi Dennis!
I've been thinking about this configuration since you brought it up, and it seems to me that it might reduce second harmonics whether they are caused by non-linearities in the suspension or the magnetic structure. Pretty cool idea, really, and I'm surprised it isn't more commonly used on systems that have multiple woofers. I never gave it much thought before now, because none of my stuff uses more than one woofer. But it does seem like a good configuration for dual woofer designs whether they be baffle loaded, plenium loaded or horn loaded.
Please do post more references if you know of any. I'd like to see more quantified data, if there is any that's available. Looks to me like you've found a good thing here.
