Single driver speakers. Are they worth considering ?

Long game is fine if it is not too long and frustrating. Why are they more sensitive to room acoustics than other designs ?
Sound purity, that's worth pursuing.

Single drivers are great....
....70+ years ago.

Things have changed quite awhile ago....it's harder to pull off the 'hat trick' to make things blend properly, but....

'One trick pony's' still only do one trick.

I have a pair of the Soul Superflys and they sound really good to me. They can be a bit finicky to set up properly as mentioned above but that’s part of the fun, right?

Their high efficiency means a lot of low powered tube amps become a viable option to audition.Zu also suggests some SS amps that pair well with their speakers.


A Miniwatt N3 for example, has more than enough power to make the Zu's sing and go to ear-splitting sound levels. Pretty much any vintage receiver works great too.

Looking at an article form Sublime Acoustic they noted that "the capacitor and inductor values drift with temperature. When you turn up the volume the values will begin to drift, which causes the effective crossover frequency and other characteristics to drift, which  can lead to distortion of the sound."
Before purchasing my speakers, I probably spent 6 months reading about speaker performance and concluded that if all possible it would profit me to eliminate crossovers as much as it is possible to do so. 

This is another coaxial speaker; there is an add on tweeter ("super-tweeter" per Zu). The main driver functions to slightly above 10KHz.

No crossover (though filters). Still not a true full range single driver speaker.
