Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

It is not just the large front baffle and space requirement that works against OB, they do not go as deep bass-wise because of the lack of reinforcement and because of out of phase cancellation.  I personally don't give ultra deep bass a high priority, so OB speakers are attractive, but, the market seems to really put such a premium on ultra deep bass--hence the use of subwoofers, popularity of high wattage solid state amps that can deliver bass punch, etc.  

A lot of the modern speakers with their very narrow front profiles sound the way they look, to me--thin and lacking is weight.  I do wonder if not enough concern is given to baffle-step and diffraction issues with some of these thin baffle designs.

The Nenuphar might have slightly deeper bass than putting the driver on an open baffle. My friends 10 inch lii driver on the open baffle I described is flat in large livingroom to 40hz and 5 db down at 30. The Nenuphar cannot move that much air at lower frequencies and that is why there is the Basis.....the Basis adds low bass and punch and the smaller ported cabinet for the full range makes it roll off the lower bass on the full range driver.....so it will play louder without overload. You could do the same with an open baffle version of a Cube.....you add woofs underneath and you change the coupling cap in your tube amp or whatever that creates a 6db per octave rolloff on the main driver areound 60-100hz without adding any crossover parts. If you use a better quality cap in the amp....then you have another boost in sound. Lots of ways up the mountain. Creativity and an open mind are king.

@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.
