I don't know anything about the actual engineering goal, but there was apparently some thought at that time that if woofers and tweeters were on the same plane, something bad happened. I'm familiar with the Genesis 3, that used the Burhoe woofer and tweeter (but added things), and they have a piece of plywood on the front of the baffle, to bring the tweeter (and midrange) forward.
