我有兩組westlake audio的喇叭BBSM-12+BBSM-5

是很多年前老爸買的
因為現在沒在聽,我就把它拿來組前置和後置,自己再買ONKYO當中置加上
DENON AVR-1800 / PIONEER DV515

我想問的是在westlake audio的喇叭後面貼一張標語:
" CAUTION
nominal input impedance 3.8 ohms. minimum impedance = 2 ohms @
some frequency.use only with amplifiers rated for 2 or 4 ohm high current operation.use short minimum loss cabling and low loss connectors.XLR connectors are not low loss and shiuld be avoided.
"

有大大可以幫我解釋嗎?感激!
