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..

that's because this type of tweeter needs a LOT of power to get as loud as a normal tweeter would need.
unless you are giving pure sine wave like most watches have in their beepers

trust me
they may sound nothing at all but they actually sounded extremely soft till it's inaudible anymore

^ the sonic gear speakers are also magnetically shielded. notice the ferrite rings bonded on them. higher end edifier like S550 also use those kind of shielding.

more info

is it 12V X 2 - 1.25A?

didnt have time to read through all the posts.

But to answer TS observation - that is a capacitance driver, not an inductance driver.

ITs not uncommon for tweeters to be based on capacitance as it can be more efficient.

If you really suspect its fake or not working, try to measure the capacitance at the tweeter leads with a multimeter.

The reason you may not hear anything from it doesnt have to be that its fake, several valid reasons below:
1. Your sound source (file or signal, including DAC/ Soundcard) does not have high freq. sound. YOu can check by trying a sine wave generator at 10kHz and above.
2. That tweeter / driver itself is not very efficient or sensitive.

I dont work for any multimedia speaker company.

In the end you get what you pay for.

the main purpose of this tread. is some how notify user to be aware of what they are buying.
and the fact that they use a cheapo tweeter is seriously cheating.

as for ur comment. i don't see some how it's helping, except you are trying to deviating the focus of this thread.
performing a capacitance measurement on tweeter? blind test? measuring the requencies respond of the speaker?  do you expect a normal user to perform all that before they buying one speaker? else anythings happen ,then the representative can blame back customer that they didn't perform the required test.. and it's their own fault of buying blindly? or they pay for what they get? because of cheap price giving an excuse of the company to use jerky parts??

then might as well ask all ppl to beware to eat outside.. paying RM 4.50 for mee goreng,, they shall have to leanr all ingredient that used in the mee goreng.. where it comes from. got halal or not.. and prepare to bring some poison detection kits so they can test the food got poison or not..
else they kena food poisoning. the tauke can always blame.. u shall know that RM 4.50 u pay for what u get..lol

i mean.. doing a blind test on a RM 150 multimedia speaker .. what kind of results you are going to obtain??? if their ear is so sensitive and they are so experience to do blind test. they don't even buy a multimedia speaker instead of a proper hifi. normal user just barely depend on the outlook, and the advertisement / spec published by the company.. no matter what kind of excuse given. they do play a fool with the spec.

as performing measurement to the frequencies respond of the speaker? i myself own a not bad entry level hifi that cost almost RM 20K currently. i don't even have a proper decible meter. because it's too damn expensive and i cannot afford a good one for use of one time only. if user get a cheap one to measure. the speaker company might still able to argue saying that the decible meter is not accurate.. no calibration ..measurement taken in user house which has bad acoustic properties.. like damping of high frequencies is too much.. not taking measurement in silence room.. WHAT EVER REASON oso can give..
and midrange that is good enough to cover higher frequencies? that's ridiculos that it will apper on a multimedia speaker.
a mid that is good enough to cover high frequencies anytime will cost RM 2K per PCS. take example of a compression tweeter. second hand of cheapest altec lansing (hifi, not multimedia) driver, anytime u throw out at RM 1.8K anytime ppl will grab it. do u think it will appear on a sonic gear that they cut cost so much even on the PCB? so far the cheapest mid that can cover high is used on AEGO M. and that's about RM 700 retail price.
in respond to the underlined parts of ur comment  : there's no point critics back the user that they are smarts or not.. so do you mean that 7Eleven who bought a sonic gear without test and performing measurement of frequencies respond is not smart?  .. user bought it. and found it's unfair. posted it in forum. i found there's nothings wrong. . anyway i believe customer who was dissapointed with it will learn a lesson them self. and be more careful the next time they purchase a speaker.

this thread is good. no matter what reason a sonic gear give...  they still using bad parts inside.
i personally found this tread is very good. while 7Eleven did a good job of comparing different brand speaker internal at the same price range.
this can be a very useful future reference for customer who don't have a chance of buying and ripping them off before knowing what they are buying.

keep up the good work 7Eleven...
