Buon Natale!

Merry Christmas!

How are you?
I did not have big progress in loudspeaker technology development.
I am creating my software document with all variable lists, used equations and algorithms.
Document will be the most important to leave the record of research and development.
I create the first detailed document, then begin to revise the program.

I wish you Merry Christmas and a Happy New Year!

Mechanical Matrix MMX Speaker System

Image
 I noticed that installing speaker drivers both L and R channel to same chamber makes stereo effects more than ten year ago. It was a test model for MCAP-CR application. Primary focus was to verify if thin film bottle could substitute for speaker driver membrane. The answer was "no"; however, it was found thin film bottle can be used as MCAP-CR subchamber. This system has both L and R drivers in the main wood chamber. I was curious about stereo effect, though L and R were installed closely. I recently tested above effect with 8" full-range drivers (photograph below). This model has two (L & R) FE206E frivers in same chamber. Real sound field effect was given by this system in big room. Now let us see the system of electrical matrix speaker system (let us call "EMX" speaker system) below: EMX is electrical wiring system with unbalanced amplifier whose negative terminal is grounded. Balanceed amplifire may not be used for MMX system. Mechanical matrix speaker

Real Giant...!!!!

This is the real giant. It is the first ever commercial product of multiple-degree of freedom cavity resonator type loudspeaker system! She is the president of DreamsounD where my friend devotes himself for true high-fidelity music presenter loudspeaker system. You will imagine how big it is!　She is not a dwarf. Once my friend wrote to me since he got interested in MCAP-CR. He had other multiple-degree of freedom cavity resonator project. I helped him for a little bit analysis part. He was really much impressed with the performance of the model. He wrote to me that he had never experienced such presence of music with the new system. I wish I could hear it. France is too far from Japan. Visit DreamsounD for more details. Ciao!
