Full Range Drivers

Single driver speakers can run the gamut from stellar to down right crappy,just like any other type.You can't just make a general assumption that they are all good/bad or sound better/worse than multi-driver speakers.The good ones I have heard,Tannoy to drop a name,are IMHO every bit as good as any speaker I've heard.If you name a few speakers,you will probably get more responses.Of course this is just my opinion,feel free to disagree.

By one set of parameters your telephone is a full range driver. If you are looking for 20 to 20K range, you will not find a driver that can do it.
I use a horn with a compression driver that extends from 400 Hz. to 14Khz. Below that I have a 15 inch woofer which meets the horn at 400 and extends just below 50 Hz. Most guys on this forum would consider that unacceptably limited. I find that it covers most of the musical spectrum. At my age, high frequencies go to waste. The woofer delivers a sensuous, relaxed and accurate bass response so I'm happy.
What are you trying to learn? The advantage of a full range is no crossover. The disadvantage is compromised extension. Everything involves trade-offs and attendant choices.

I can't disagree. I've never heard one. I find your response appropriate considering the lack of information I provided. I'll try to see if I can demo some Tannoy's. I've heard that some full range driver configurations do a good job of reproducing vocals, I would imagine if implemented properly. I think my 3 ways do a good job, but have nothing to compare them too. I'm under the impression that no speaker does everything perfectly, so maybe I should look into having a second pair of speakers on hand for certain types of music. I'm probably crazy and just going through some weird 'collect bug'.
