Mega D'Appolito Speakers - The Holy Grail?

At SpeakerCraft/Marcof we were building MTM arrays before Joe came out with his well deserved praise for his development. Joe was trying to eliminate lobing error independent of inter-driver phase relationships.  Most of the time Joe used all 18db slopes and drivers that had a smooth transition in the mid band. I could speak extensively here,  but If I read the ops starting message, I think the main question by the op is... Are larger speakers that incorporate an MTM design, inherently better in some way than other methods. 
Done well,  I would normally rather listen to a very good MTM over the same drivers in a 2 way design.  However, when you step into large 3 way or 4 way well done speakers.  I cannot say this is the case.  Many large speakers sound quite good in dynamics, a large midrange transducer to have that extra air moving in the mid band,  shoot,  I've heard some pretty terrific 15 inch 2 ways. So for a direct answer, I would say no. The attributes that you mentioned are not necessarily better in an mtm over a non mtm in Large speakers.  Legacy Aeris comes to mind as a great example. 

Hi @timlub
Thanks for your contributions, here and elsewhere.

I _really_ did a poor job of explaining myself. I'm really not thinking of D'Appolito 2-ways.

I'm thinking more of large expensive towers with drivers arranged vertically around a tweeter which are at least 3-way designs.

So it sounds generally that you agree, midrange surface area/dynamic range is a big deal, more so than the lobing and arrangement of the drivers?

Best,

Sound contains different parts and all these parts influences our emotion. These parts have nothing to do with personal taste. This is a 100% nonsense story what most people believe. I also believed it for a long time.

When an audio system can reveal more parts on which sound is being build it will become more intens and emotional. No audio system what reveals less parts on which sound is based will be chosen by anyone.

Most systems are imcomplete based on the fact that these people build their system on trial and error. And they have no idea which properties each single part in their system owns.

You want an audio system that sounds as real as possible and be able to reveal as much details and information what is on the recording.

You only will buy incomplete audio systems based on the lack of knowledge and wrong advice. Each single person on this planet will always choose for that sound what can reveal as much information of the recording at the most natural sounding way.

Trial and error is an ineffective way of choosing any audio system and this is based on facts. They let people believe that this is the best way of creating a personal system by taste.

This is 100% nonsense, because you can never control or build any audio system when you have no idea what the properties are of each single part in your audiosystem.

Trial and error is like gambling. When you cannot answer what the properties are of the loudspeaker you own, you have no idea what it is able to reveal. Because most loudspeakers are incomplete based on facts.

They miss essential parts on which sound and music is based. What is missing can never be created by anything. This part is missing, so you never can reveal all the parts of the recording. And it doesn't matter what you connect to it, it will always be incomplete.

You only can understand audio when you understand music and sound. And how it is being formed and which properties each part in your audiosystem posseses.

Then you can build and control your own sound. When you change a part in your audio system and you cannot answer the question; which properties you took out by changing this tool for this tool. You have no idea  what you are doing.

This is audiogambling based on facts.
