Glad to see you'll be making some sawdust. I am concerned about the planned center channel, however. You should be aware that the cone is white, and people who use a center with no grill might find it distracting. Also, the woofer routing on the flat pack baffle is too big--you won't be able to get screws in vertically and there will be a gap left between the frame and the routing lip. And, the crossover is completely different, so the Meniscus parts kit won't work. I would also note that the new woofer goes just as deep as the old--it just can't play quite as loud down there. Although it is smoother on top, the overall system response isn't any smoother. The new woof just allowed me to switch to second order slopes for the woof-to-mid cross and boost sensitivity a little.
