@larryi    I have only heard two or three OB designs but uniformly, they all exhibited a thinness, a lack of weight or gravitas, that left me wanting for more. I'm not saying they can't scale the heights but I haven't heard it.

As the OP, I've asked once and now I'm asking again. Both have been polite requests. I do not want to engage Admin and have multiple posts deleted.

As @toetapaudio  and @larryi have suggested, and I have requested...it is easy to start a thread on open baffle speakers and other full range speakers. 

Thank you.

David,

Why is a discussion of the suitability of the Cube driver for use in OB systems not an appropriate subject for this thread?  It appears to be a thread about both the speaker and the driver.  
While I have my doubts that this driver would be better sounding in an OB (because I think the designers would have tried it this way), I nonetheless think it should be an excellent candidate for such use for fans of OB speakers because of its overall competence.

@ricevs I’ve been thinking about your detailed suggestion for rewiring the Nenuphars and wonder why you wouldn’t just procure enough of the wire you are using internally to go from voice coil to amp, skipping "speaker cable" altogether?

The internal speaker wire is short and you can use a high quality one to replace it. For external wire, if you are content with the internal wire and never plan to experiment, you can always extend the internal ones externally as well but remember than the external wires are usually long (unless you are using monoblocks close to the speaker) and will need extra attention to shield and all. If you plan to experiment with speaker cables then its a pain to desolder/solder every time to change it.
