two way v. three way speakers


I recently heard some magico mini's at a friend's house. They sounded amazing. And they were 'only' a two way speakers, but they filled the room with amazing sound. So now I wonder, what does the additional driver add, especially when it is the same size as the second driver. For example, the SF Olympica III's have two drivers of the same size. I know that third driver adds a lot to the price, but what does it sonically? Thank you all in advance.

@Maxboy00 - I wasn't intending to imply that we were not in agreement. Sometimes forums, like emails and texting, cause a failure to communicate. We need a more resolving forum, right?
the one ways i just had built beat my old 2 way kestral 2's and my paradigms studio line 2 wys. consider a full range if you really want some drop dead musical presentation. audio nirvana was the brand i got, the 8 in full range classic 8's. i could add a sub but i live in a condo so unlikely and tbh i do not really need it at normal volumes. spend as much as you want on any high quality make or model. i hooked it up to a $300 7 watt tube amp. yes they are very efficient! imo, 2 ways and 3 ways are no0 better or worse than the other..depends on engineering, drivers, crossovers and on and on
I own the Mini 2. In the right room, the right system and properly set up, this two-way can astonish. I chose it over the 2 1/2 way V2 and the 3 way V3, primarily because of its coherence and neutrality. In my system, the Mini 2 provides a very big, dynamic and room filling sound, even when pushed to extremes. But this is not an ordinary two-way speaker. It was designed and built to an extreme standard.

I agree with some other posters that it is difficult to generalize between two and three way speakers. Perhaps a three-way will be slightly more efficient, a bit more extended and less restricted during very demanding and complex music, but I think it really depends on the individual design, size of room, type of music and amplifier that you plan to use.

Apparently, the Magico Q1 is an even better speaker. I suggest you listen to some 3-way speakers in other settings and perhaps go to a Magico dealer and compare the Q1 to the Q3 or the S1 to the S3 to at least compare similar designs and philosophies while also hearing a 2-way versus a 3-way.

Should be a fun process.
It depends about the quality of the brand and crossovers. Magico is exeptional good also in crossovers. That is why they can make an exeptional good 2 way speaker. There are only a few on this planet who can achieve this. These days I am only interested in speakers who can give a wide and deep stage. All 2 dimensional speakers ( most are) you can dump in the ocean from my point of view.

Many 2 way miss the fullness in the mid freq. On the other hand many 3 way have a lack of playing fully loose from the speaker.

At the end there are only a few brands who make exeptional good quality what makes audio really special!
