Feel your pain bro, i sent my N7 in the middle of the Jan and they also told me to wait for their speaker spare parts to arrived after CNY. But the next day they said got stock and be able to collect it in subsequent day. Now my speakers are in good working condition and i think it's even better than the ori one.

BTW i was warranty my unit at Lowyat Asus Service center, where is your warranty place?

Yeah... that's what i suspect, coz they told me that other service center got the parts but reluctant to spare some to them... but in the end dunno how they got the spare unit... anyway, how's ur new experience on the new speaker?
