Czarivey,
I do not know how they work but I can give you my opinion for what is worth. I have owned two different single driver speakers.
I owned The 2nd Rethm with an upgraded Lowther driver with an upgraded silver voice coil driver and wired with Crimson speaker cable for 15 years. I enjoyed ther clarity but they were a little too “shouty”. It is hard to beat the huge soundstage, midrange and bass clarity. The limited bass depth was sufficient for me. However I found that the treble was a bit too cut off and grainy. They were also hard to integrate into my living room decor.
I now have a pair of Audience 1+1 V2+’s in my main system and the smaller version called The One in my office system. I maintained the midrange clarity, soundstage and gained treble focus.
I won’t tell you that multi driver speakers are better or worse but I all I can say is that once I compared single driver speakers to multi driver speakers is that I preferred Single Diver speakers since then. You might want to get a hold of A pair of the Audience 1+1’s, try Galen Carol Audio, he may have a thirty day return policy and are only the size of a medium sized toaster. This makes them easy to move them around and set up.
I have also heard the Tocoro’s, another single driver speaker, I found those quite compelling as well. Dreamonoids, in San Antonio, TX sells them so you might want to give those a try if you are curious about a larger single driver speaker. You might want to audition those as well.
One thing I have experienced through the years is that the cleaner the power delivery, power chords, speaker cables and interconnects of good quality elevates their musical clarity.
Have fun,
