效果絕對好過同價位10" (依家好D 10" 都要6K....)
不過同p13u個D 有所不及(話晒都成16k..)
不過我目標係5-6ksub
如果下次我會比多d買 US$300 Up ge Driver
同買大功率amp (我而家得230W@4Ohm)

FeedBack Destroyer model 係1124P
係舊MODEL (而家出到2196), US 要$99
無Auto EQ ，要手動
即係用REW度 再 manual or auto REW 較部1124P
av100fun 有post教人用REW度roomEQ

Feedback Destroyer 係一個Equalizer
例如你要tune 某一/幾個Hz ge dB (當然係你用mic 同REW 度左之後)
你可以靠1. 擺位 2. EQ 去tune 個 db Curve
