mga sir e2 po ung guideline sa rating ng mga speaker, continuous power rating/RMS - pwede po sbihin din ntin e2 ung thermal rating ng voice coil ng speaker or how much the speaker's voice coil can take without burning up, mas malaki diameter ng voice coil mas mataas ang kyang ihandle ng speaker, kc mas malaki ung thermal surface (area) ng voice coil at motor assembly para madissipate ung init ng voice coil. At 2% conversion efficiency po ng speaker, ung iba po ay heat nacoconvert. program/music power rating or nominal - usually twice ng continuous power rating hence only 3dB higher compared to continuous rating, very typical po sa dynamic range music ntin (processed) peak power-usually 3 to 4 times higher than continuous power rating, e2 nman ay rating ng mechanical limit ng speaker nyo.Ang nagdidikta po d2 ay ung suspension at Xmax (voice coil overhang) ng speaker nyo. Ung voice coil ng speaker kya po nya maghandle very high burst of power at a limited time lasting about a few milliseconds without considerable heating up ng voice coil.But those high burst of power means higher voltage drive from the amplifier hence higher excursions. power compression- phenomena po e2 sa speaker, kc when the voice coil heats up tumataas po ung dc resistance (Re) ng voice coil, hence lumiliit din po ung current na inaabsorb ng speaker, thus reducing power. ung malalaki ang voice coil na speaker mas maliit ung power compression mga 1dB to 2dB, kc madali nila nadidisipate ung init.While smaller voice coils are around 3dB. Kung ang power amplifier nyo ay my rating na 100Watt at ang power compression ng speaker nyo ay nsa 3dB it means 50watts lng ung naidedeliver ng amplifier nyo sa load.sana po makatulongnagmamahal,audiomachines
