"Scenario (2)You're having a Saturday night dance party and playing killer urban bass technopop (which is at 115 BPM) at a level of 105-110dB. Each of those synth kick or bass hits pulses the driver with perhaps 2000 watts. IN BETWEEN the hits, the caps in the power supply charge up and so the smoothed AVERAGE draw from the power line might be about 1000 - 1300 watts."
我應該去唔到105db.....

可以找人改220V直插,大陆很多人成功了。 JL 單元仍用發泡膠邊,雖然加厚,但香港天氣潮濕。價錢就和老麥一樣,美元定價加運費 x 7.8。 ...

可以找人改220V直插,大陆很多人成功了。有冇資料睇睇? 放大器功率: 2500 瓦RMS 短期 ,咁未要買隻好大先得

啲前輩講220v轉110v最少要買大一倍功率,如果唔係會唔夠力。
如果2500W,咁真係不如畀人改220V好過

預多500已夠 啲前輩講220v轉110v最少要買大一倍功率,如果唔係會唔夠力。

發泡膠邊是美式傳統低音單元邊,唔係cheap唔cheap問題,JBL4人幫大衣柜用佢,佢速度和反應比膠邊好,但寿命短。 真係唔好講少,一是HK代理願意收錢換牛,JL 應是用Class AB Amp,換咗雜嘜牛聲都变埋。

Yes
乾濕得多會粉碎
