Nope, not sure how to do that, Noah.
But 2-way WG speakers cannot eliminate a floor/ceiling/wall bounce below the woofers directivity control point to match the waveguide, nor a ceiling or wall (front/back or sides) bounce (NOR can CBTs below their control frequency). You don't see too many freq responses at people's seats from their individual L/C/R speakers due to this, unless it is quite strictly gated. Even coffee tables make freq responses look pretty terrible with wide gating. Is it audible? Some say yes, others no....some people will take the hit in freq response to be able to put their glass of wine down on something.
Woofer/WG speakers have a narrow sweet spot induced by nulls at the crossover frequency due to the C-C spacing between woofer and WG. Go past the nulls and you may find that output still exists past them, contributing to the reflected sound power unless dealt with by absorption/baffling/other means.
In a baffle-wall setup with an acoustically transparent screen and an absorptive ceiling and thick carpet with thick padding backed by thick felt, Woofer/WG speakers would be incredibly tough to beat. Without a baffle-wall, and no absorption on the ceiling, but good wall absorption hung on the walls (front/back and sides), a proper CBT using the ceiling as a groundplane could be very good, and provide all rows with essentially the same presentation, even with surrounds very close to listeners, the close and far listeners would hear an equivalent spl (if implemented properly), and the surround effects would not necessarily collapse to one speaker.
Do not get me wrong. CBTs have their shortcomings. 3dB per octave falling response in the high registers means equalization or careful crossover design is important. The low cutoff for directivity control is dependent on line height and curvature. Center-to-center driver spacing limits the frequency at which control is maintained in the higher registers. A near 1/2" C-C spacing on CBT36 means control out to almost (if not at) 20kHz. Most tweets are larger, and will have finite control limits. You also need to purchase many drivers (and drive many of them with less than full power, so some sensitivity is lost), and come up with an acceptable shading scheme and crossover. Your response in the transverse direction will be dictated by crossover nulls (just like vertical nulls in W/WG speakers) as well as the amount of curvature of the array. Small drivers that can dig deep enough to cross to subs and still play well up high enough to cross to small tweets are not easy to find, especially if you only have receiver power to feed a stack of them.
They also have distinct advantages over line arrays and point source speakers, as noted in the many papers Keele has put forth.
Like any speaker design, they are not a panacea (large Synergy horns need not necessarily apply here, as they are LARGE). They do fit a niche for certain directivity needs coupled by a nice form factor (tall/slim).
