I'm playing devil's advocate here because I think your argument uses a hand picked example that is not necessarily representative.
The ear does not hear waveforms as such; rather, it deconstructs the incoming sound into energy at different frequencies. So waveform fidelity is not nearly as important as eyeballing what happens to a square wave would lead one to believe.
Square waves are very good predictors of fidelity.
After thinking about this a bit, you are probably right about off-axis freq resp vs phase as a predictor of sound quality. Phase isn't usually considered unless there's a gross anomaly like a suck out. With multi driver speakers even if the phase difference is compensated there will usually be a difference between what happens at the crossover region and the rest of the band of the driver(s). It's not so easy to correlate with perceived sound quality. This depends on what you consider important. Square waves are very good predictors of fidelity. This is true in electronics and in speakers. For instance, waveform fidelity usually shows the difference between a dynamic driver and a full range electrostatic. Differences can be dramatic.
I wonder if audibility results would be similar if the freq were 1K rather than 100Hz.
Would doing this digitally have the same effect as putting the signal through discreet components?
Midrange is king (at any age) and that is where single driver designs shine. As doorman indicates coherency (especially nearfield) is perfect. Imaging (single point source) is ideal. And by default single drivers are "active" (one channel of amplification per driver) which adds dynamics, allows the amplifier to "see" the simplier load easier, and increases depth/volume of bass significantly.Crossovers may be necessary, but are always evil, especially in the midrange frequencies where the ear is most sensitive to phase mix ups.If you've read through this circle you'll find no concensus on a definition of a single driver design. The purists say one driver period, but that's hard to find that provide satisfying bass without sacrificing the highs. Some say woofer with tweeter is OK if the tweeeter only has a capacity to protect it (no "real" crossover). Others look towards a smaller driver with a subwoofer added. Etc/etc.For older ears I'd lean towards larger drivers that can handle more bass better. OTOH smaller drivers "beam" high frequencies less.The downside of single driver designs is that they don't handle loud/complex types of music as well as muli-driver designs. There is no perfect loudspeaker.Also search for Planet10 and brinesacoustics.
Thanks for posting Mike.I can't quite tell what brand/model those speakers are, could you tell us more?TIA

Thanks for the link. Too small for my taste.
Chris, now you're picking on me. I'm just a simple farm raised boy who could never bring himself to spend that kind of money on speakers (unless they came with a car or a super model).
well then the Oninyanma might be more to your liking (line of credit permitting ) these I didn't (and at $14,7000 /pr maybe don't want to) hearCount Olsonovavich, have you heard the little 85WK after their measles attack?
I recently purchased the HoytBedford type 1's. A single 8 inch driver in a beautiful wood enclosure, 48 to 18,000 freq.response, & 97 db rating. I've had many speakers in the past decades (I'm 50 yrs young) and they all had multiple drivers. The sound that radiates from a pair of qualitly single source speakers is amazing- the soundstage & depth is unmatched. Jazz & opera are life like in my living room.
