Yamamoto Sound Craft PB-23 African ebony spike receiving base

It can also be used in combination with PB-9 and PB-20 as a pin type base. When combined with PB-9 and PB-20, the upper and lower surfaces are flat and easy to use. Recent audio products require a base for receiving spikes in many products with spikes. The PB-23 is 59mm in diameter and 20mm in height, making it suitable for large weight-grade speakers and amplifiers.

Metal is often used for these pinpoint bases, but metal spikes often produce resonant sounds unique to metal, and PB-23 is wood, so it prevents unique resonant sounds and provides comfortable and clear playback sounds. In particular, when receiving a metal spike pin with a metal plate, resonant sound is easy to ride, but by combining the PB-23, the metal spike can be eaten moderately, stabilizing and preventing metallic resonance.
