Single driver vs traditional 3 way loudspeakers

@bache   In my specific application / component chain, and with the balance of components I've worked with to get there, no. 

 Very good ,  but for my experience and design, if you choose Single driver , the baffle need big size  https://forum.audiogon.com/discussions/wide-baffles-and-baffle-step?highlight=baffle  

I like my 2 way no crossover Ref 3A de Capos :)

@grinnell  you wrong  , look stereophile specification 
   
Description: Two-way reflex-loaded loudspeaker for use with stands 26-28" high (not included). Drive-units: 1" impregnated fabric-dome tweeter, 7" woven carbon-fiber cone woofer. Impedance: 8 ohms. Sensitivity: 92dB/W/m. Frequency response: 44Hz-20kHz, ±3dB. Crossover frequency: 3kHz.    (  that mean you got crossover )

Not having a crossover network the De Capo instead uses Mundorf Supreme Silver Oil capacitors as a tweeter high-pass filter.
