正盛多数低频振动器支持 4-16Ω 可选，便于多点并联或长线驱动。选型要同时看额定功率、供电与通道数，避免功放过载。
Most Zhengsheng LF vibrators offer 4–16Ω selectable impedance for multi-point or longer wiring. Match rated power, PSU and channel count to avoid amp overload.
家具内多振子阵列时，较高阻抗有利于降低单路电流、方便统一功放驱动；近距离单点大功率也可选更匹配的档位。
每通道额定功率 ≥ 振子需求；总功耗与电源余量；线径与长度压降；是否桥接 PBTL。ZSTD 多通道驱动器可同时驱动音频与振动通道。
In multi-vibrator furniture, higher ohms reduce current per channel; single hard-punch mounts can pick a better match.
Per-channel power headroom, PSU margin, cable drop, PBTL bridging if used. ZSTD drivers can feed audio + vibration channels.
