If it is a SMPS (Switch mode PS) no problem...if it is inductive then " Houston! we have a problem"...inductive motor may run faster on a 60hz, inductive transformer may induce a bit higher...but then again they have tolerances...so they "May" operate just the same if Timebase ( some apps needs clocking from AC line) is not a problem.

this is just may take...you have to dig a little deeper on this, you dont want to waste Money Right?

have a nice day,

Thanks for the quick response sir Jo, but how do I know that it is a SMPS? any solutions to make it work in pinas? Is there a converter from 50hz to 60hz?
Sir Jo meron pa po akung tanung, (I have other question) I planing to set up a mini PA system for north cotabato particulaly in Kidapawn city , I have a QCS RMX2450, would this match with pd1851 single on 8ohms bridge mode or parallel the 2 speakers bridge mode? and what box to match this speaker?
Thanks
Edwin

If you see a big xformer and big filter caps inside your amp then it is inductive type but if you see just filter inductors and HV caps + MoSFETs then it is SMPS. The PC power supplies and also of TV, Monitor,DVD player and even CP chargers are example of SMPS.

50hz ac motors well work for 60 hz AC line with only a slight changes in speed, but not a really a problem.

PD1851 ng Precision Devices?...may project ako sa http://talk.philmusic.com
it is Build a Hybrid Horn Loaded Sub-woofer.

I recommended that speaker driver. go there and download the plan...then watch the video animation for the step by step procedure.

have a nice day,
