Many thanks to Dhar for helping to bring this project together. He put in far more hours than he should have, including time fixing my mistakes. I have to say right here that many members of this group have given a lot of their time over the past few years to help me with various projects, and/or shared their knowledge with me. I'd just like to say how much I appreciate it. Thank you very much, Dhar, Dave M.,Dave B.,Tom, and Charlie.
These speakers are available in a kit form, or just as CNCed baffles from Joseph Crowe. He's very flexible and will make slightly different variations like a longer baffle for a floorstanding speaker if requested. His original design was using the Satori 29mm softdome and 5" midwoofer. I asked if he'd modify it for the BE tweeter and Purifi woofer, and he did so at no extra expense. He has a YouTube video of this model comparing it to using the same drivers in the same volume box but with a faceted baffle for more typical wide dispersion.

There is an issue with the Purifi woofers having so much excursion that it demands extremely long ports or multiple passive radiators to play deep. The engineer at Purifi recommended a sealed enclosure. The box size is 16 liters and is crossing over to subwoofers at about 60hz without a high pass on the monitors. Opted for this route as opposed to a 3 way as music in this room is generally played at very low levels and I wanted flexibility to still have deep bass response without adding subs under a 3 way, as well as the extra expense of building larger more complicated speakers.
I lost my listening room during a recent remodel of our home and now have a more modest system in our livingroom under dreadful listening conditions. Wide dispersion loudspeakers were not working there. These speakers sound lovely and with their excellent off axis performance and controlled dispersion there is a stable image in almost any seat in the livingroom. The midrange and treble are just natural and engaging, even with generic electronics in the chain ahead of them. I'm looking forward to trying them with some better gear soon.
I'm not sure if Dhar has distortion measurements but they are extremely low. Here's the step response and null.
