MMX Drawing example

 MMX is abbreviation of Mechanical Matrix loudspeaker system, which was described in the previous blog article. Without hearing an example system, it will be difficult to imagine its sound field. I added sample drawing below: http://mcap-cr.com/mcap/drawings/MMX-2_drawing-set.pdf This system is actually made. I enjoy listening music with this MMX-2.

Mechanical Matrix MMX Speaker System

 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...

Recent Works

My blog update of this page is too few. I have been updating my Japanese blog every day for recent years, but updating this English page takes more time, I feel reluctant. Recently I am building a new 4" class MCAP-CR system. Here is the drawing of the newest system. I recently pursue the simplest and the cheapest applications. This model requires least pre-cut of a plywood. Size of the plywood material is 1920 x 910 x 9. Most loudspeaker enclosure builder prefer heavy gauge woods. On the other hand, I prefer light gauge materials. Why? I do not own a car, therefore I have to transport materials by public transportation. I will again update this blog when I made the system.
