Gold plated will look like oxidized, but rub with tissue or cloth it got back to shiny surface again, no cleaning agent needed.
And it took long time to accumulate that layer.

If you plug your headphone on to your laptop same problem happens??

That could possible your 3.5mm female on your lappie is faulty...
When you use WD-40 did you rub it hard with tissue?? I did mine and it don't look more shiny, but when I plug in it is much more easier.

Hmm...so i think either you take it to warranty or mod the wires and jack yourself since all these steps is not working....

I use fishy aquarium filter
I did look on that polyethylene foam before, but it looks like will do reflection than absorb to me so I didn't use it.

I had look on to this before, the Magic Foam


but it is too expensive to try, one big size need around RM20 plus. The foam does look nice and has very fine pores....

Nope it is not memory foam or yellow scotch brite foam. Quite rare I can say, I saw such a fine texture of foam before is in the Lamp Berger box. But this Magic foam is for cleaning purpose so i'm not sure it is the same or not.

Putting foam inside satellite and woofer box does improve, but for tuning you can't simply put too much, might feel over damped...depend on preference.

Last time I used cotton but now use aquarium filter mix with cotton, feels better to me. Maybe I'll try preview current mod sounds like, there is a lot tuning after my last preview vid.

Because I really see the speaker on its limit, so I didn't plan to go for more tuning and mods again...

Digital from onboard sound card i'm not sure about it, can be worst can be better, i'm not sure how is your result...

Because I had did some research before, that a digital data from SPDIF from digital source is not nice square wave, some is worst than analogue because it introduce huge amount of jitter. Optical as transfer said to be very good, but there might be a big problem on light source has response, introduce jitter too.

I stuffed aquarium filter at sideway in the enclosure, meaning the basket holes is cover with the filter but the rear are not. The basket 'spoke' is tied with cotton foam, prevent early reflection.

Yea it is overkill mod already lol...because I did all my experiment on it...but i really like it because it will gives out emotional feel from the music although the tone is not good.

When you look back the original M3300 tweeter and compare it to my modded one, you'll noticed something

Didn't actually calculate it, but estimate around the price of RM3xx for materials used on it, if include experiment cost then it will be a lot more.

Improvement? I nearly forgotten how the stock M3300 sounds like....but I know the improvement makes this speaker goes to different level.

You may try view around other speaker preview videos, I know it is not accurate but can be an estimation.

Yea true that must sit in front of the real one.

No worry, you have headphone~

Well it is a test recording how does it sound on decent handphone or camera....have listen to be real one be accurate results...
