Hello! These are my bookshelf speakers that i have been working on here is Few pictures in finished form and did some measurements aswell. Bass response isnt accurate so ignore it. Im probably trying to tweak the tweeter response to make it more tilted down. These use Peerless NE180W woofers and Seas 27TAC/GB Tweeter in shallow waveguide.

Very nice. Did you make the waveguide? Or was the baffle for sale somewhere?

These were old waveguides that i bought years ago and they happened to fit that seas tweeter with little modifications. I glued the waveguide to the baffle and just filled it flush.
 
Honestly, the tweeter is maybe 1 dB too hot at best, it may be difficult to get things any better than they are. I wouldn't trust the spin until you've got all the measurements needed.
It has good horizontal and vertical measurements from 300hz upwards. Ill try to make more accurate nearfield bass measurements soon.
 
Very good drivers, and one of my favorite domes. I would add between 0.5 - 1.0 ohms in series with the tweeter, right at the xover connection. BTW, use a sandcast resistor. I tried some MOX, and they added sibilance.
