Mega D'Appolito Speakers - The Holy Grail?


The engineer, scientist and author Dr. Joseph D'Appolito has a speaker arrangement named after him, a vertical array of mid-Woofer, Tweeter and mid-woofer. There is more to it than this, as the good Dr. has written quite a bit about crossover design needed to achieve good results.

I'm not necessarily talking about a true D'Appolito speaker though. I'm rather thinking of large speakers which have a central tweeter in between increasingly larger drivers. MBL, Dunlavy, Von Schweikert, Legacy, Gryphon all have built some version of this idea.

What do you listeners think? Is the dynamic range, detail, transparency, distortion and imaging consistently better than other type of designs?

Best,

E

Like Ricred I also own the Pl-500 from Monitor Audio. For this money you will never find this level in sound quality.

It outperforms in stage depth, width and especially in diversity in height the Magico speakers.

But the D’appolito system creates a level in physical appearance you seldom wil hear. It makes voices and instruments so much more physical tangible.

Beside this the level in grip and authority is of a different level compared to other speakers who have no d’appolito system. The ease and accuracy in grip is really impressive.

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.
