Generation of a Speaker

        

    We want to free ourselves from a filter distributor. We want the band-width the most extended in the low register and the acute one. we do not want volume higher than 100 liters. We do not want materials of damping. We want to avoid the standing waves. We want implementation a simplified.     We will choose an adaptation of acoustic impedance type to obtain the largest band-width in the low register. We will choose a broad band LS. We will avoid the parallel walls. We will choose the diameter of the LS not too large not to obtain a too great volume. We will choose a LS with a good output to compensate for the small diameter.

The plan for a volume of 98 liters. In the form of a pyramid to avoid any standing wave.

 Here, we made the choice deliberated on a single loudspeaker of good invoice. Our principal motivation was the simplicity of implementation compared to final quality to obtain. The simplicity of assembly of the loudspeaker leaves the place with a more delicate assembly of the enclosure without a material of professional. It is besides the party which we took by entrusting the realization of that Ci to a cabinetmaker. There remained to us nothing any more but the assembly part, cablage of the loudspeaker and sealing of the unit. Results: - a low cut with 35 Hz - an output more than correct of 93 dB - an extended band-width, without hole nor bump - the true low ones, a great sound cohesion And especially a great pleasure of listening with a really single and personal object.
