原設定的分頻點?
另外箱體設計,容積?開口截面積?開口深度?
低音單體fo?
當初設定的箱體共振頻率?

For frequencies below the vent resonance, polarity inversion is not accomplished, and backwave cancellation occurs. Furthermore the driver behaves as though suspended in free air, as box air springiness is absent. This is a far more significant problem with vinyl record replay, because in this case there may be significant subsonic content in the audio signal, due either to warped records, or to turntable suspension wobbling or acoustic feedback.

因為看到這篇,所以,想知道你那喇叭設計是否注意到這點?
你的前級擴大機能砍掉極低頻否?

不可能如廠叭的理想
只要發揮某些特色就好

高音汎美兼具厚度
中音寬鬆寫實
低音尚能融入,還有調整空間要努力(年假功課)
