想問下SVS pc-13u 同 pb-13u 既分別
邊只好d, 除價錢同外型外, 大家爭d咩同邊只会易拍邊d 本帖最後由 r32 於 2010-1-16 08:25 編輯聽講兩者差唔多, 除咗 : 90 lb vs 155 lb之外, PC低頻衰減得快D, 同擺位靈活D, 有地方揀PB-13U啦.

Copied from web, acticle written by jjj, sg. :
Having played around with the new PB13U and PC13U for a week,below is my short reports .
The drivers built is. Even push hard (tune at 10hz/sealed,room gain = off) , the drivers still no sign of bottoming , clean and good bass .(Using Flight of the pheonix to test)
There is a new adjustment on this new ultra -- Room gain.
You can set small,medium,large or off(see instruction booklet) . This is to compensate the room gain on different sizes of rooms. The effect is to slope down the deeper freqencies, using your own room to increase back so to get a flatter response .
I myself set to "off" because I want powerful deep
Compare PC13U to PC12U , PC13U is taller . PC12U will tend to have loud port noise when a sudden powerful deep bass chime in . PC13U also has but very faint , so do the PB13U .
Overeall initial impressionWill try to watch more deep bass materials in future and see how .
Both is as powerful. "Very faint" refer to port noise . PC12U(set at 10/15hz) used to have loud port noise when SUDDEN push hard(example:hill have eyes 2 , scene when a head pop out from toilet bowl.) 2隻都未聽過拍邊 & 未聽過'會'拍邊 {:6_142:} 聽講兩者差唔多, 除咗 : 90 lb vs 155 lb之外, PC低頻衰減得快D, 同擺位靈活D, 有地方揀PB-13U啦.

想問下咩叫低頻衰減 "想問下咩叫低頻衰減?"應該話頻率越接近10Hz時, 個喇叭輸出音壓就越細聲. 10hz係一個好低頻率,冇幾多隻落到
svs好利害{:6_193:}

Sealed subwoofer 10Hz無咩可能出呢個聲壓﹐一係就加多幾隻
