single driver speakers


Someone please help me out here...

I am struggling to understand how a single driver system can sound anywhere near as good as a multiple-driver system with crossovers...

I understand that crossovers and multiple drivers can have issues with interference, phase, etc - but those drawbacks would seem to be vastly outweighed by the increased frequency response and clarity within a frequency spectrum that a multi-driver system produces.

I see these

and just can not wrap my mind around how they could sound better than a multi-driver system costing 1/10 as much. (no knock intended on the seller of these speakers, I was just browsing listings and saw them so it made me wonder)

Thanks!

Folks are completely unaware, _______, of this new 21st C technology that has been around since 1929.
All I can say is
Unreal.

For 2 years I would look and look, and look over DL's PS drivers on ebay,,having no clue what they were all about, But maybe they were more than something cool looking.
I finally figured out what you , back then in 2018, were *struggling** to grasp.
I;ve got the whole equation, puzzle all figured out now.
Took some experimentation, and thinking, thinking, pondering, tweaking, adding, subtracting.
I just hung on and now have all the answers.
The PS technology is from 1929, and  had some developments over the years, 
Then died away completely, Now has resurfaced as 
The New 21st C Super High Tech Speakers. 
My guess is , if the Tampa bay Audio Show has these New tech speakers, news will spread like wildfire, and you will have a wait time of months to get your order filled. These things are not mass produced. But surely worth the wait. 

Good quality single driver speakers tend to excel in coherency, which to me is a key ingredient for the highest quality sound. That to me alone explains the attraction, regardless of the downside. All designs have advantages and disadvantages. How those factor into a final value judgement is completely up to the individual.

There are also many time and or phase "coherent" multi-driver designs out there to compete. Ohm Walsh/CLS, Thiel, Kef UniQ, Tannoy concentric driver designs, mbl, for example, are some that come to mind. I currently own both Ohm Walsh/CLS (coherent line source) and kef UniQ-based speakers (ls 50s and ls 50 metas).

I’m a tough sell personally for any speaker design that is not inherently "coherent" .

Large speakers with multiple drivers all spread out seldom cut it for me in comparison. Requires a very large room for those to integrate time coherently at ones listening location.


It’s been around for a long time, The point is it will NEVER catch on.
For those that think a single driver can do it all, good for you. It can’t.

OLD hat, old tec.. 300hz and below a round VC speaker with tuned phase plugs.

300 hz and up Small Planars or ribbons. NOTHING even gets close, to that combo, EXCEPT more of the same...

I did hear a few Narrow Baffle LS dome systems that were pretty good.. I’ve use a narrow baffle 10" or less for over 20 years, THAT was the real game changer for me.

A single driver NO WAY..

2 watt amps are fun too, just MOST people don’t use them. It’s as simple as that. The FUN wore off quick for me.. I was 25 or so I’m 66 now.. I still have a SET or two around here.. Cute things.

Kinda’ like Tribbles on Star Trek.

BTW this is POST 40+ in over THREE YEARS.. No it’s NOT what’s to come AT ALL.. Maybe 5 in the last 2 years, AY?

I admire your tenacity if nothing else.. Show me something GREAT. I'm all ears..

Regards

OK fair N sqaure,. 
One size does not fit all. Agree. 
Have not  lsitened to any of these  speakers you mention. 
Heard much raves  on the Tannoy Concentric. 
have no idea on the prices which is a  concern for me and many others here, considering the economy straights  of late.
So seems PS does have competeing designs.
I'll accept.
I will now take a look at some of the speakers you mention on prize, szie, weight and if YT has  some offerings.
I can tell you this 1929 FC has a  alluring stage presence.
