Single way or multiway

In my younger days I was all for a multi-way, but nowadays I can usually handle just a single way before it's time to call it a night and cut the music.

@simao LMAO!!!

In contrast, some other well-known and equally respected speaker companies — such as Voxativ, Zu, Cube Audio, and Totem — use crossoverless designs.

Who is right, and who is wrong?

@bache There are two issues: Doppler Effect distortion and beaminess.

The former contributes to congestion at high volume. The only real solution is to remove bass excursion from the driver. 

The latter causes the highs to be hard to hear unless you have your head placed in a vise. 

So a crossover is needed to solve both problems. 

IOW there's no such thing as a 'full range driver'. There are however 'extended range midrange drivers' such as the ones you listed. If you treat them as such you will have much greater success with their use. If you don't use a crossover, they really will only work at low volumes. 

I have a pair of Tangband 8" drivers in a sealed box crossed over to a matching Fostex tweeter. They are driven by a 5 Watt amp. I use them as monitors in my electronic music lab. They work great for that since I only use them at low volume.
