"All good things go by three“ is a proverb we often use in Germany if something happens the third time. The new ES-28N is the third model in the current EPOS line-up, and on top of it, it’s a 3-way loudspeaker made by a designer who is well known for doing 2-way systems even with bigger woofers. So what did change his mind? 
 
Experience! It’s just that a 2-way system is not working so well in a configuration with two woofers. OK, there is the typical D’Appolito configuration with a woofer above or below a tweeter, but as the tweeter should be sitting around one meter, the speaker would end up as a huge tower. Mounting the woofers below the tweeter would need a so called 2.5-way configuration. In such a configuration, one of the two woofers stops working in the lower midband, and the second woofer covers the rest of the midband to connect to the tweeter. That sounds like a good idea, but unfortunately, the main radiation axis for those two woofers would be tilted downwards, so it is difficult to manage the mid-frequency energy properly. So why not make it 3-way? OK, that’s what we did.
