ching,其實十仔set幾多都冇問題,最緊要係自己鐘意,再唔係就可以揾D ching家訪一齊玩吓囉 ...

師兄,想請教下如果我屋企隻hrs10, 喺test tone嗰時個sub仔既volume校到一半多Ｄ，跟住部amp既sub仔音壓要校到去+8db，先至可以度到80db, 咁做有無問題？會唔會個amp既sub仔音壓加得多得濟會有問題架？因為聽過其它師兄好似講過話最女子+-唔好超過3db!

Onkyo 機要到+8先有80db,應該唔正常. 你個音壓計有無set c同slow ?
  有d較平音壓計,度低音好多時都唔準.
  如果你個音壓計係用緊舊電,可以換舊新電試吓

順口請教吓, 我做完自動音場後SUB 仔距離比真實差好遠,Check test tone 得個 45dB ,其他Speaker 75dB, 咁係咪有問題? 應該點Set 好??

Usual practice is 75db all channels to ensure channel balance, but that of course does not take into consideration personal preference, which anyone can do anything they want !!

Do take into consideration there is correction table for Radioshack meter for its inaccuracy at some frequency, depending on whether yours is analogue or the digital model - http://www.subwoofer-builder.com/SPL-corrections.htm

Unfortunately not too many ching mention about the correction needed.
