subwoofer set up 入門

[GundamZZ]

I'd like to know where to buy a cheap but good 聲壓計 ? What's the brand and model ? and around how much ?

Thanks...

any brand is okay,unless if you want to use BFD for eq-ing of sub, then you need radio shack analog meter. I have a cheap digital meter which I don't use anymore after I bought the radio shack. you can borrow it if you want

Thank you.

Do you mean that a special meter is needed for the BFD ? and how much is it ?

真是獲益良多, 多謝BEANBEAN兄的分享.

我都想知radio shack幾錢冋o係邊度可以蹾到? Thanks!

用BFD最好有個analog 嘅sound meter.例如 radio shack
sorry, 我叫人幫我喺美國買, 大約連shipping$600

首先將subwoofer 擺去你嘅皇帝位, 如果係sofa, 就移開sofa擺subwoofer落地, 再播一段32hz-45hz 嘅低頻

beanbean好野
呢個方法用黎set擺位,等我又試下先

唔好睇漏前面個句 "如果subwoofer 可以鰠你屋企任擺,"
不過亦可能你屋企可以做到

[brian_av100]

大家都知到一個20HZ鮋wavelength 係好鬼長, 如果空間太細未必出到所有低頻, 出倒都唔會夠feel

怪唔知上次係jhonny 屋企冇feel啦, 佢係用SVS PB12-plus/2, 但佢間th房好細. 當時我post出來時, jjj都有插 jhonny有冇攪錯

如果subwoofer 唔可以鰠你屋企任擺, 就試纒原地轉角度睇纒有冇幫助.

到咩程度為止ok呢

thanks

Subwoofer setup
經過一輪上綱資料搜集,家訪, 玩埋eq, 加埋自己玩咗幾隻subwoofer後, 綜合咗一D經驗同大家分响吓subwoofer setup. 如有錯漏, 請指教

每個牌子嘅subwoofer都有唔同嘅音色 , 由千幾蚊到幾萬蚊, 四十萬都有 , 佢地嘅作用都係用嚟出低頻, 低頻有唔同音色, 有D subwoofer 嘅低音係dup 心口 dup 到嘔血 , 有D 係收放快 , 乾淨, 有D 係肥 , 有D可出到16hz以下 , 睇吓你鐘意乜character.

Step 1: 接駁
我只係識一種接駁方法 , 就係用一條rca 頭嘅訊號線或同軸線由AVamp 嘅subwoofer out 連接到subwoofer 嘅 in. 如果subwoofer 有left, right, 咁就接left, 或者AVamp subwoofer out 出兩條線駁晒落left right又得. Avamp setting, speaker small, subwoofer on, crossover 通常set 80hz (如果喇叭細可能要set 100hz, 120hz….). 重有其他接駁唔知high pass low pass乜乜物物係比兩聲道或冇AVamp用 .

Step 2: subwoofer擺位
Subwoofer 擺位係超級重要 , 因為如果擺得唔好, equalizer都幫你唔倒 . 大家都知到一個20HZ嘅wavelength 係好鬼長, 如果空間太細未必出到所有低頻, 出倒都唔會夠feel . 如果subwoofer 唔可以喺你屋企任擺, 就試吓原地轉角度睇吓有冇幫助. 如果subwoofer 可以喺你屋企任擺, 恭喜晒 , 繼續睇, 首先將subwoofer 擺去你嘅皇帝位, 如果係sofa, 就移開sofa擺subwoofer落地, 再播一段32hz-45hz 嘅低頻 (綱上download 隻test tone CD或等我揾人打堂齌 燒隻比你 ), 而家再喺你個廳周圍行吓, feel吓邊個位最大嗚嗚聲, mark 低呢個位, 咁即係話如果你個subwoofer擺喺度, 當你坐皇帝位就會有最大低頻感覺.
如果冇test tone CD, 就揾隻勁多bass嘅concert cd, dvd.

Step 3: subwoofer phase
正常嚟講, 有subwoofer就會喺AVamp set speaker 大細做small, 咁低頻就可以比晒subwoofer 出, 調較phase其實唔係只係較前置同subwoofer關係, 低頻其實係波浪型式由subwoofer單元同音箱輸出, 如果條波浪啱啱喺低位先行到你果度, 咁你就feel唔倒有bass. 如果喺高位打落你度, 咁你對果個頻率就係in phase. 如果你屋企細, 多數好難由16hz-80hz全部頻率in phase. 超低頻好難做到in phase. 冇辦法, 天意, 買間大屋啦 . 試phase 最好用63 hz-80hz (如果crossover 係80hz), 喺皇帝位聽吓有冇嗚嗚聲, 有就in phase. 冇就扭吓 phase個掣 (揾friend幫手最好), 扭到聽倒有嗚嗚聲為止, 最好可以扭掣扭到當你個頭向前小小都聽倒嗚嗚聲就very good. 如果你個phase掣只有0, 180, 或 +,-, 咁就唔駛玩咁多嘢, 兩嘢就試倒喇. 冇test tone cd就又係揾隻勁多bass嘅concert cd, dvd. 或 HiVi Cast, Avia....

Step 4: Subwoofer volume
如果有聲壓計, main speaker用AVamp test tone 會set 到每個channel 大約75 -78db. 其實聲壓計就算set main speaker 都可以用c-weighting. 咁 subwoofer 就一定要用slow, c-weighting. 通常耳仔對bass冇高音咁敏感, 所以set 78-85db就差唔多. 不過我鐘意用concert cd, dvd, or DTS-9用嚟set subwoofer 大細聲, 我覺得重好, 因為有人鐘意bass多D, 有人小D, 所以都係耳仔收貨最好.

Step 5: Enjoy
搞咗咁耐機, 一定要睇番多D 碟, 如果唔係買套機嚟重乜 , 好多人搞機重多過用(包括我 ), 有時買隻碟番嚟剩係試一兩段 (講緊你呀 ). 算把啦, 同屋企人relax吓再搞過啦

以上只屬個人意見, 如有錯漏, 請指教
