Achieving truly realistic reproduction requires speakers capable of much higher levels than this, ideally around 130 dB SPL. Even though the level of live music measured on a (slow responding and rms reading) sound level meter might be in the region of 100 dB SPL, programme level peaks on percussion will far exceed this.
130dB這數字之前見過是在交響樂團指揮的位置測得(難怪許多指揮年老時都重聽...),
這數字根本沒幾對喇叭唱得到,
那些四件式大喇叭總會用一堆高音,例如Nola GV,或是Genesis G2,都用上一大排高音
就是為了盡量放大振膜面積提高音壓,
但以我實際聆聽的感覺,我想,還差很遠啊...
