single driver speakers

Altec 755's in a two-cubic foot sealed box will give you satisfying bass and enough treble for pleasurable listening!

A lot of folks like Zu  fans is considered thah single driver with supertweeter  or without is the best

I think some of this is mythology, and much of it is personal taste. In the past integrating multiple drivers was really difficult. Multi-way speakers pre-date the electronic spreadsheet, PC’s and of course crossover simulation tools by decades. A lot of trial and error and wasted time IMHO. This is why some of the Genesis speaker crossovers are so utterly wonky.

Some of this has to do with where we hear individually. My suggestion, rather than going on argument, is build a pair for yourself. Some kits start at $150 per pair:

Some advantages are time co-incident, and point source behavior. That is, going off axis there are no possible lobing or interference patterns (depending on the actual driver design). In this way they act like the old thiel, and modern co-axial TAD or Kef designs. 

And let's face it, they appeal to the purists. Multi-way speakers, on the other hand, are complicated. Lots of capacitors, coils, resistors, etc. are all participating in the final result. It is fair to question whether any of this detracts from 

If you want a multi-way with an absolute minimalist crossover, consider the A26 kit:

Voxativ used like with  Pure Audio Project use woofers  just formidbass,low bass the purity of the single driver can shine 
But No 1 driver can do it all.  I havd iwned,No names these 15 inch 
Full range drivers ,in s proper large ,cabinet, they too have peaks 
At certain midrange frequencies that can be stringent .
I now have a excellent monitor- monitor sudio New Studio coupled to their engineered stands.
Flanked by good Subwoofers. And sounds Excellent- don't let the price throw you off it is more accurate then any speaker under $10k
A Mega best buy,for under $2k buy at least 1 very good subwoofer
I have their Silver W12selling st 45% off ,older model.,there are several very good Brands of Subwoofers

As pointed out by some of the replies above, single drivers have wonderful midrange, speed, tone, timbre and clarity that is hard for mutiway drivers to match. For example, a piano covers a wide frequency range. The bass will be covered by a woofer, mids by either a smaller cone driver or a dome mid of different material, impedance, sensitivity, dispersion,  compared to the woofer. And the high frequencies of the piano will be covered by a tweeter, again of different size, structure, performance, measurements etc compated to the mid and woofer.
In a single driver, the entire piano’s frequency range is covered by the same driver acting as a point source, which is the ideal. Consistency, coherence, no phase changes, smmoth imoedance curve etc.
Another key point of single drivers is the high sensitivy. They don’t need a lot of power. You can use direct heated single ended power amps. And that's another argument between solid state snd tube amps.
Note that most owners of single drivers started with multiway systems.
Keep an open mind, go listen to a well made single driver, anything from a Zu, Rethm, Voxactiv etc.
