Spike receptacle base made from African Black Wood PB-23

9,000yen (4pcs. set)

  Spike receptacle base PB-23 is the amplifier and the setting base for speakers which are used combining the spiked type base of independent or others. The material is using the 1 African ebony material (formal scientific name African Black Wood) of the hardest material also with high intensity in all wood. Although this material is a rare material now, it is the material actually used for the oboe and clarinet of a musical instrument, and there is established reputation in the merit of that sound. Although I sell PB-9 and PB-20 as a pin type base, it is also possible to use it combining them at our company. When it combines with PB-9 and PB-20, it becomes easy to use an up-and-down side at a plane. A base for there to be many products with a spike and for the latest audio products receive the spike is needed. The diameter of PB-23 is 59mm, Since height is as large as 20mm, the speaker and amplifier of a large-sized heavy weight class are suited. Usually, although metal is used for these pinpoint bases in many cases, a resonance sound peculiar to metal appears in metal spikes in many cases, and since PB-23 of our company is wood, it can prevent a peculiar resonance sound, and it can obtain the reproduction sound which cleared up comfortably to the ear. If a metaled plate receives a metal spike pin especially, resonance sound will ride easily, but by combining PB-23, a metaled spike eats away moderately, you make it stabilized and, moreover, metallic resonance can be prevented. If it combines with PB-9 of our company, and PB-20, the sound which was stabilized more and was massively carried out by the increase in the mass will be obtained.
