Single driver speakers. Are they worth considering ?

IMHO:  You might as well get  BOSE 901 monstrosities.  What could be better than 16 three inch speakers facing the back wall, and two facing the front?  Maybe a MegaBoom?  TeeHee

If you only listen to acoustic folk, vocal, unplugged, at moderate volumes.

 Some of those single driver speakers do sound amazing.

 Depends on your music. If you like electric guitar stuff with bass guitar, and other stuff like that, I would say go for it.

 If you like some volume sometimes, and like rock and roll, 3 or 4 way towers, or monkey coffins are the best bet. 

@mapman ...+100 ;)

But it's hard to be heretics....*G*  They keep coming at you with the torches and pitchforks... "WassamatterU?!*
 *LOL*

...but, the original Ohms were single drivers, as are the HHR 'flagship' units....

The current Ohm offerings are 2 driver units, with a 'Walshed mid & bass driver with dome tweeters.  Heresy vs. 'bottom line' costs?  Perhaps...

My diy 'clones' have gone to a Walsh tweeter as well.  And I eschew using a cabinet for the low bass for a subwoofer....which is omni by physics anyway.  Heresy sublimation?  Well, yes.  But the final effect 'may' be closer to the original intent....imho.

We can discuss....and I can always opt for 2 subs....;)

Multiple materials applied to a single driver strikes me as having inherent weaknesses, even with modern materials and adhesives.  That, and the decision where to place the 'physical crossover' from one material to another seems problematic and a potential issue to be avoided...

But, I'm just an outlier with an attitude...*s*

That...and a 'footprint' in a given space is dinky....against a 'monkey coffin'.  9" dia. x 42" tall, vs. what? 😒🤷‍♂️

Beat that.

Cube Audio complete Nenuphar speakers were out of my price range so I purchased F10 Neo drivers via Refined Audio and had  Salk Sound build the cabinets - to Cube Audio specifications. I am very happy with  the result. The first thing that hits you is the bass: it is BIG, the biggest I’ve had. The sound is very detailed and dynamic, even at low to medium listening volumes. I don’t find it fatiguing at all. When they first arrived I spent the whole night listening to various favorite albums and enjoying the newfound clarity. This set replaced Tekton Design Double Impacts which are great but came out more muted in comparison (or, using the audiophile cliche, you could say “veiled”). They never reached the lowest bass which goes down to hell with Cubes. I spent a week or two switching between DIs and Cubes. To be completely honest, I think DIs have a bit more presence in mid bass but it seemed more muddy - definitely not as punchy and satisfying as Cubes.
I am driving them with PrimaLuna Evo 300, rarely going past 1/4 of the volume. I also tried First Watt SIT-3 and found it very comparable but a tad too polite and not as engaging and alive as PrimaLuna.
