Depands on the quality of you rsubwoofer, your in-use sub cable and how long you are using.
If you have to use a very long subwoofer cable, choose a better one, of course.
現今Subwoofer設計是供接駁AV 5.1/7.1和兩聲道兩方面使用，接駁和調校有所不同，現就只提接駁。

Ching, how about subwoofers with LFE jack? For brands such as Velodyne, they actually recommend to use 1 to 2 connection.http://forums.audioholics.com/forums/archive/index.php/t-18652.html
Thanks.

1. What you mentioned is only the discussion between two persons in one of the forums, not the Official Manual issued by Velodyne.
以下以中文敍述。
2. 以DD Series為例，如以XLR 接駁，DD series就只得一個XLR Input。
3. Subwoofer是設計出來接駁stereo和AV 5.1/7.1用，所以大多有Phase control, Stereo Input, Crossover Point 等等，以上都是用在接駁Stereo system。
4. 市場Subwoofer線大多都是單一條售買。
5. LFE/低頻是單聲道。
以上2-5都是解釋本人說法，當然玩AV/HiFi是很主觀，沒有定律，玩AV5.1/7.1接兩條Sub 線入一隻Subwoofer，本人認為無必要，用了亦無正面影响。

謝謝師兄回覆，我本身其實係初學者，不過由唔同既外國source見到好多人都係話1出2會比較好，而Velodyne官方亦建議用Y-splitter接駁LFE jacks比較好，可參考 http://www.polkaudio.com/forums/showthread.php?t=8640. 不過呢個thread內亦有同師兄你差不多既睇法：
"Regarding the Y splitter - unless the sub's dual voice coils are not wired together (unlikely unless you buy a DIY driver like the Tempest), there is no difference in sound. Adding a Y splitter doubles the voltage and it adds 3 dB in volume and - yes - helps with sleepy auto-on circuits. If Velo recommends it then go for it."
另以下文字是從VX1 menu內擷取出來 (http://www.velodyne.com/vproducts/docs/63-VX11%20Manual_Rev%20B_web.pdf)
Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor, integrated receiver, line-level crossover, or receiver with pre-amp level outputs. These devices will often have a Low Frequency Effects (LFE) jack which is dedicated for subwoofer use. When using the line level jacks, some receivers may not provide enough signal to have the unit’s auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of. To alleviate this condition, we recommend the following steps:
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED – never use just the left or just the right input. If the subwoofer’s input comes from the LFE channel of your receiver, use a “Y” splitter to divide the single input into two inputs for the Left and Right subwoofer inputs. This dual male-to-female “Y” splitter can be found at your local electronics store. If using line level connections from a preamp or signal processor, use both Left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer.
我對上文既理解係，行1-2可以較易叫醒隻十仔，不過唔知岩唔岩，亦希望可以有比較淺顯既解釋，知道咩野時候應該1-1，咩野時候就1-2。
多謝師兄分享
初初我都係用舖頭係買機時，將雞線扮貴線俾Discont你線
攪到我覺得個sub仔好唔掂，點教都覺得唔掂，可能係新仔
哈哈，跟住想換sub仔，點知換咗條好多師兄話好sub仔線
成個sub仔精神咗，依家換sub仔想法可以慢慢想，以前用1＞2
現用1＞1線覺得低頻清楚咗個人意見，新仔乜都唔識
咁我想問一吓,若原本用緊系一出二的SUB CABLE,但只插SUB仔的其中一個接口(R or L)會不會比同時插兩個會好一點? 還是要用返一出一先得呢???
你可以用依家條線試咗先免得浪費錢
我用新線1＞1接sub仔L input之後較大db值，
你可以同一setting，1＞1 之後聽吓，再試1＞2
睇吓邉樣好，但係1＞1 有change講會小3個db所以較大db
我覺得線材一定有幫助
新仔乜都唔識講錯唔好打臉，
