[#29] 加左個十仔聽歌呢個 subwoofer, 特價 1000元全新於原音買, 但回家發覺音量細左 d, 遂拆尾板, 取個分音器出黎研究, 原來有粒錫屎 short 了線路, 至只得一個低音單元發聲, 修理番, 聲正常番, 兩個低音單元推挽式經氣孔發聲, 氣孔可加導音膠管調節音量, 我沒加, 才合意。生意人肯特價, 有原因的, 細李生經手, 內裡沒放大線路, 亦省去每次聽歌要開電源制, 1000元就真係扺最後修改時間: 2026-02-19 01:09:21		美好日子會員 116.xxx.xxx.18	2026-02-19 00:56

幾十年前雷明用8隻 MK passive subs聽歌.
我平時用一隻REL Strata supplements main speakers 聽歌, set 到sub 隱形就算數

#20, 內裡沒放大，只是兩个輸入，R，L 各自獨立輸入內裡，兩个 bass units 推挽輸出，輸出口可插膠管調低音量，我就發覺不插管就低音量己足夠，亦最自然

Dual active driver , 如 SVS 都只得一部 amp
“Harnessing the colossal power are fully active dual opposing 8-inch SVS drivers connected in parallel to move in perfect unison for massive slam and output with crisp, musical transients. The usable surface area of two fully active 8-inch woofers firing in opposite directions unleashes performance on par with much larger subwoofers and the tight, punchy output obliterates multi-driver passive radiator subwoofer designs known for bloated, one-note bass.”

兩個獨立分音丶两個單元丶即是內面要有兩部 amp, 應該吾平
大部分sub 仔為了曾強輸出丶多用單元一推一拉丶真係未見過丶獨立運作

Better use two sub as many sub has a internal crossover that has high cross talk between left and right channel.

A way to test is to unplug one side of the signal cable and see if the unplugged side still has sound coming out from that side of the speaker.

If this happen, you need to get another sub to isolate left and right completely or add an active crossover for the subwoofer.

Even with floor standers, adding subwoofers will help with the whole acoustic experience.
It is not about how much bass, but rather how the subwoofers could smooth out the LF response/ room modes.

Agree with dual subwoofers better than 1, yet 1 subwoofer is better than none.

Paul McGowan from PS Audio and John Hunter from REL Acoustics are strong proponents of using subwoofer for music reproduction/ listening.

Worth think of listening level. If lowish listening level, say 60dB (instead of reference 80-90dB), might want to dial the subwoofer volume output a few dBs higher than the stereo speakers, to compensate for the perceived truncated LF (Fletcher-Munson curve).

Yanki 師兄：

以為啲Subwoofer低音反應無咁快，加咗上2.1聲道會怪怪地，低音一舊舊，睇戲反而無所謂，因為專注力會放在畫面上面。現在啲Subwoofer進步好多，單元/功放/DSP… 反應速度跟得上原本兩聲道喇叭。
