Once you develop more sophisticated senses, you will be able to do that too.
The only exception of which I can think is a speaker whose mode of operation is not immediately apparent. For example, just by looking at a Quad ESL-63 (or subsequent models) one cannot tell that it's designed with delayed segments so as to mimic a section of a sphere.
However, what cannot be done is to tell if a speaker is any good just by looking at it. Too many variables.
That is to say, one can safely exclude obviously bad designs (basically, anything with a flush-mounted tweeter and a >4" midwoofer), but just because something looks like it
could be good, that doesn't mean it is.

Actually, one can determine quite a bit about how a speaker will measure just by looking at it. If one sees a speaker 7" midwoofer along with a tweeter on a 180deg waveguide, and knows the approximate crossover point, one can make reasonable assumptions about the midrange energy that speaker will throw into a room.
If one sees three tweeters on 4" flanges in vertical line, one can reasonably infer that the treble is going to be Venetian-Blindsville.

To the middle point, yes they are. Everything else has poor horizontal off-axis response by definition.
The first point is a judgement call, and some have lower standards than others.
The third is an argument for Bose and monster cable, just not relevant to high-fidelity music reproduction.

You seem to think you're an expert, so where is your award winning design? I'd love to give it a listen. Will you be at RMAF or any of the audio shows? I think I already know the answer...

I prefer to make money, not burn through it. I don't have a speaker business because I wouldn't be good at it. Furthermore, there are plenty of companies already offering speakers along the lines I discuss: Revel/JBL Pro, KEF, Tannoy, Gradient, TAD, GedLee, Seaton Sound, Genelec, AudioKinesis, Soundfield Audio, Emerald Physics, JTR, Quad, Danley Sound Labs, etc. So even though most speakers offered are crap, there's not really a lacuna in the market. There are speakers of potential merit in every budget.
Note that many of the above design their own drive units and either build them in house or source manufacturing for them.
And if you look in the DIY forum, there's a big project centered around some very interesting new SEOS waveguides.
