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.

The freedom you own for speaker choice all depends about how much your wife loves you.

It is al about love! :)
wow, this guy is so far beyond human knowledge he cannot get subtle jokes any longer. whew, i am tired just reading all this brilliance. i have a full range driver so i am happy alone just listening. no need to ask permission from anyone.
He is walking, talking, audio databank of thousands of components that he has personally tested and whose results reside only in his head. The models that consistently rank at the very top in Bo's world are coincidently those that he sells.

He cannot tell you what equipment he uses for his tests. He cannot provide written results. He can tell you that he has done this for 16 years and therefore, must be right. So buy the products he tells you to. That coincidently are the ones he sells.

He is a true Audio God. Funny though, the last I bought something from someone that said "Bo Knows". I ended up with an overpriced pair of Nikes.

I'm sure he won't get this joke either.
It is a lot more simple: The best sound Always wins. I create my sound ( a 3 dimensional physical stage) and people can audition it.

At other shops they can listen to sound for the same kind of money. So they can compare. What do they choose?
Exactly the most convincing sound.

People read and listen very bad. When you would have read better you would have undersand that it is not about me.

The quality of the stuff I sell is what counts. I only use it more precise. Better quality sells a lot easier.

What I said earlier; we have a totally different kind of humor. More on the sarcastic side. It has nothing to do about understanding.

When you use Pioneer ( 2 dimensional standard audio) as an amp you have a lot of knowlegde in audio!!
