It is better to let the port move the air freely instead of mesh blocking there...

How about cut out for better fit?

Good then, but also remember the toroid tranny can be hot, make sure it won't melt the the filter.

I suddenly thought of an idea, using some car protectant or wax on woofer port, making it smoother airflow. I'm not at hostel all these days I can't try it

Just a thought, can try and do no harm...
It is a poor man style of reducing air turbulence.

Hmm...maybe toroid tranny is more efficient so less heat, I had mine quite hot, reaching 60ºC and still not enough to burn up the filter but long term might possible to melt some.

No kidding lol, just to reduce air resistance.

Coz when I heard B&W woofer bumping almost max volume, there is almost inaudible port sound when you put your ear near the port. Its port design is unique....

That made me thought of importance of port turbulence

What model speaker is that?

I just recondition my speaker cone surround with auto silicone spray...seems like it has been dried when bright sunlight is shine in to my room...

Now it is much more ear pleasing~

omg not the cone bro...that gonna spoils the sound by soften it seriously...

only teh surround rubber

I remember when I'm young I had phobia on oiling the speaker cone, I used car leather protectant to shine up the cone then end up blurry sound comes out...become very very bad sounding because the cone soften already. After that I start to apply carefully on the surround without touching the paper cone.

PP cone and metal cone are ok with it...it is built to resistance on moisture and it is much harder than paper cone.

To prevent moisture affecting the sound you can try apply very thin layer of PVA glue reinforce it, but becareful and do it at your own risk.

omg that in the end I test NE5532 opamp for my speaker and prefer it after all the other opamps I had in my hand.

Use it to keep the surround soft is more effective.

I tried auto silicone spray to lubricate all the connectors, prevent oxidize seems promising and the lube is very light that won't make the whole connector oily...

But then I plugged back everything and testing any channel imbalance problem then found out everything sounds thinner

Can actually try enter Hifi shop and ask for audit on their demo setup...that might able to worth thousand words.

Around budget RM250 you can try out M3300 or M3300SF with 25W RMS of subwoofer power it is enough for vibration effect, if you want ceiling board shake and windows grill shake then you need to fork out more.

e3350 is a one of good speaker that give overall quality too but i'm not sure about the bass.

Your bedroom size can learn kung fu fighting one?

Anyway, don't max out the bass volume then it will be ok for not annoying the neighbor.

if you like boom boom sound from Altec Lansing MX5021, Edifier normally cannot do that because different sound signature but Edifier is good for overall performing.

For your price range, if you don't mind about 2.0 speaker, give R1600T Plus a try at price of RM280 if not wrong.

Hmm...all the time I was wondering how actually Edifier design a new speaker and release to market?

Wops, sorry for asking too private and confidential question.

Very thanks for the info anyway~

If you willing to spend more for better experience then go ahead, if not then stay on board one.

I jelly T.T

Try out blu-ray live music concert, it is nice

It has better recording than most nowadays of popular pop album, together with high quality video.
Audio recorded in 24bit-96khz.

That is the strong point of blu-ray.

CD has normally no multiple channel because it is limit already with the normal format

Blu-ray disc has capacity of 25GB for single layer, normally movies took around 12GB?, so it has space for high quality audio.

DVD-Audio has quality with 24bit-96khz but that is a rare stuff.

And normally DTS audio has multiple channels, mostly I saw it use for blu-ray disc, there are normal CD using DTS audio and requires the to support such format in order to play it.

Recording in multiple channel took a lot more work compare to 2 channel.

There are always mod or changing speaker option
