Yamamoto Sound Crafts PB-23 African Ebony Spike Receiving Base set

It can also be used in combination with the PB-9 and PB-20 as a pin-type base. When combined with PB-9 and PB-20, the top and bottom surfaces are flat and easy to use. Many modern audio products have spikes, and you need a base to receive those spikes. The PB-23 has a diameter of 59 mm and a height of 20 mm, making it suitable for large, heavy-duty speakers and amplifiers.

Normally, metal is often used for these pinpoint basses, but metal spikes often produce a resonant sound unique to metal, and since PB-23 is made of wood, it prevents the inherent resonance sound and provides a clear reproduction sound that is pleasant to the ear. In particular, it is easy to get a resonant sound if the metal spike pin is received by a metal plate, but by combining it with PB-23, the metal spike can bite into it moderately, stabilize it, and prevent metallic resonance.
