I got this thought after my 13 months old SG Evo3 spoilt.
I decided to dismantle it since it's not workingand no warranty. I discover some interesting stuff after i dismantle it and want to share with all the forumer.

SG Evo 3 spec - Sonic Gear Evo 3

For the spec, they claim that this speaker come with 2 x 1" Tweeter

Let me show u, how the tweeter like

A tweeter without magnet , how it sound?????? I just realize, this is why i can't hear any sound fr the tweeter when i closed my ear to it. Damn..

I will dismantle my Altec, Edifier and Eacan speaker soon.

if i am not mistaken.
that are infact drivers too
remember old timer ATARI game machine (tetris, Donkey Kong,) were using this kind of tranducer to produce some high pitch sound.
if i am not mistaken too. my Gshock watch actually uses same type of driver to produce the BEEP sound.

PS: i am not sure. because i though it was a buzzer. hm... high pitch buzzer?


EDIT : found the name of this kind of driver.
it's called Piezoelectric driver.

wei post this to Sonic Gear fanboy thread... see what are their reaction

lol, its a sonic gear, what do you expect? I have been working in one of the biggest IT shop in lolyat years back and Sonic Gear speaker has the highest fault rate followed by altec and edifier

china, US, canada

I never liked sonic gear speakers from the start heh, the demo units on lowyat shops sounded piercing to my ears last time i listened to it.

I never like any of those 'brand' speakers.. the reason why I bought BOSE instead..no offence guys but to me they just don't sound right.

well before i started listening to book shelf speaker, indeed altec lansing sounds good to me~

in fact edifier bass is great


until i started listening to bookshelf, i never wanted to look back anymore and sometimes i went into my parents room to listen to my old altec to REMIND me how great bookshelf speaker is lol

Actually, the same goes for the M2 I think.

Sri Comp?

I am using a5 ehe /

LOL...
Great finding. My sis used to work for SG too in pc fair.

sweet
I love pics of dismantled speakers
always wanted to see what's inside

btw those are piezoelectric buzzers
those buzzers are tweeters that doesn't need a crossover to protect them.
can't wait to see other speakers dismantled

i oso keep thinking. if it is fake tweeter. why they so borther to solder cable on it. it waste 2 wire and worker time too.
could it be a peizo tweeter covered by plastic infront to mimic normal tweeter out look?
hm..

lol yea

that time i was incharge with warranty department
