訳有出品 YAMAHA subwoofer YST type 22x22x22cm 3.4kg

This is a used cubic YST subwoofer for the YAMAHA surround system TSS-20, featuring a simple Yamaha design that fits anywhere. (This speaker became available separately from the system for a specific reason, so it is being listed individually. Please read the following description carefully.)

It utilizes Yamaha's proprietary YST (Yamaha Active Servo Technology) method, which achieves bass reproduction comparable to large-scale systems. (Since the speaker does not have a built-in amplifier, it will not produce sound or even turn on unless it receives a YST signal that also serves as control.)

Please purchase only if you are familiar with the specifications of Yamaha's dedicated system terminals (YST, etc.) or if you are capable of setting it up yourself.
We cannot provide support regarding its versatility.

Please read the detailed information about this speaker quoted below before purchasing:

(It is understood that the amplifier must have a YST-compatible subwoofer output as a prerequisite.)
