- #15 [roger457], 12-07-06 16:47因為16kHz 以上禾都聽唔到x2
- #14 [PLL], 12-07-05 22:50個人認為JBL4425 不需要加超高 2405H .
( 因為16kHz 以上禾都聽唔到 )

最後修改時間: 2012-07-03 16:41:46 - #6 [MDLP], 12-07-03 09:30想知2405H以現今標準唔知算唔算超高?
不過肯定知就係
2405H敏感度達105dB
放在4425祇有91dB頭上
唔係加粒容可以解決的配撘問題
4425
最後修改時間: 2012-07-03 09:40:01 - #5 [kitahara0011], 12-07-03 04:451st order 3db/octave, 2nd order 6db/octave.
- #4 [albertohassier], 12-07-02 23:45我見有些是 1st order 6db, 2nd order 12 db.
係咪 2nd order 好些呢? D聲重疊左高音度會否有好大影響
