mga sir ask ko lng sa mga nakasubok n ntong paudio model n ito ,halimbawa e lagay ntin ito sa WBIN - 4 wbin/imf hp18s 600 watts kumpara sa 2 wbin/sd18el 1000 watts ,alin po dito ang maganda at malakas ...kc sa isang sd18el ay makakabili n ako ng 2 imf hp18s.... so ano sa palagay nyo mga sir..go ba ako sa 4 n IMF hp18 or sa 2 SD18el, next project ko kc ito ....kung kayo mga sir ang papipiliin alin po dito ang pipiliin nyo ,, thanks
imf hp18 is 97 dB@1m sensitivity.. sd 18el is 98dB@1m sensitivity
4 pcs of imf hp18 will be at 103dB SPL@1m @ 1w input per speaker
2 pcs of sd18el will be at 101dB SPL@1m @ 1w input per speaker
imf hp18 @ rated power = 97dB + 28 dB= 125dB still @ 1 meter (less than 28dB<rounded ko na lang> is the power difference of 1w and 600w in decibels)
sd 18el @ rated power = 98dB + 30dB = 128 dB still @ 1 meter (30dB is the power difference of 1w and 1000 w in decibels)
4 pcs imf hp18 @ rated power will be 131 db-SPL ( amplifier power at rated will be 600w per speaker)
2 pcs sd18el @ rated power will be 131 dB-SPL ( amplifier power at rated will be 1000w per speaker )
hirap na magdecide nyan,
