Hahaah 2dae learned frm Ben tat crossover cannot on full cos if on full de sound will be louder. Crossover is like de maximum limiter for de amplifier(like a gate control wic limits de max volume of the whole system. Also played my songs 2dae. Haiz is difficult to b a soundman cos if on too loud de exhibitors complain too loud dey cannot promote their stuffs. If on too soft, some of the exhibitors complain cannot hear anitin. So unfair lo cos those stalls near the stage are usually the ones whu suffer wen de speakers are on loud. Also hahahaha saw felicia chia and Edmund chen at de expo. hahaha dem stupid sia i stood beside dem and dun care abt dem. Hahaha onli find de felicia quite chio la. hahhaa 2dae dem sianic but luckily Ben brought FHM so i sit der and read de mag for 5 hrs frm 12pm-4pm! Aniwae my life at singapore expo continue 2moro...
