I made some progress on my Wavecor WF223/Scan 9900 two way - still haven't named them yet though. These drivers are spectacular and seem to love being roommates. I tried a couple different crossover topologies before landing on this one which really integrates them well and lines up the phase nicely for an octave above and below the 1400Hz xo point. My usual minimalist approach just didn't cut it this time and I spent some extra components to get everything where I wanted it.
I was excited to get measurements, so I never ported the enclosure as I had planned. I'm debating whether or not I should do so because I'm really liking the sealed bass I'm getting out of this driver (F3 around 55Hz with a shallow 12dB/octave rolloff). I suppose I could port it and then seal up the port if I don't like it as much. As mentioned in my last post, porting will give me an F3 around 45Hz with a little bump right before a similar 12dB/octave rolloff, so there's really nothing to lose and quite a bit to gain.
These Parts Express pre-fab boxes are very nice, but the baffle really needs to be braced or at the very least, glued in place. 4 screws in the corner of a 10" x 17" panel is not sufficient to minimize unwanted movement. Once I get the baffle fixtured properly and some damping material on the inside walls, this is going to be a VERY nice sounding speaker.
