Unrealistic budget, even if you aren't expecting the PSB W3 setup. I mean, you korek your wall and make sure it fits perfectly to an in wall system already cost how much? sweat.gif

RM1k is simply too low to get a receiver + a pair of speakers.
The cheapest receiver that handles 4k passthrough, all the recent codecs at a SECOND HAND price is already around RM1k. A pair of speakers, the very cheapest second hand adequate bookshelf would run you around RM500.

So looking for new at RM1k? Not going to happen.

Your best bet for under RM1k will be computer speakers (active speakers with their own built-in amplifiers). You will have to see what type of connections your TV has right now for external audio and make sure the active speakers are able to take that connection. You can use headphone out from your TV (not all TVs have this) or the RCA jacks (which are rare these days) or Optical out (most tvs have this but most PC speakers don't have it).

This is one good example I found at Mudah :
PSB Alpha

You can also find many new active speakers like Edifier, Thonet & Vander & others within your budget.

The downside of such systems is they are not scalable so you will not be able to add speakers, a subwoofer or an amp in most cases. But they serve the purpose of giving you much better audio than your TV speakers and most cheap soundbars.

Disclaimer: I have nothing to do with the ad in Mudah just sharing what I found.

Damn, didnt knew it would cost that much to build a system from scratch.. sweat.gif

Guess i'll put it aside for now. My budget for now only allows what jdgobio mentioned, which is a computer speakers setup.

i'll have to put this custom setup to the side first, still a lot more to learn. biggrin.gif

Thanks SSJBen and jdgobio for the insight

One of my tweeter started to leak sound too
Attached Image

as u see from the pix, my speaker is a full range speaker, a 3-way 4-speaker system.
it have the following spec

Impedance: 6 OHMS
Frequence Respondse: 32 Hz - 20 kHz
Sensitivity: ±89 2dB/W/M
Recommended Amplifires: 20 - 250 Watts

the prob is... i do not know which tweeter to choose...
the mix and match is not for forte...

and i only use the system for movie... not music

---

ps: if i notice some frequency is missing on one speaker... does it mean my crossover is faulty also?

Choose the same type as your existing ones or experiment with horn or aluminium tweeters?

If those are branded speakers, you might be able to find their original drivers on ebay.

I meant the same type as the one you want to replace i.e. dome / aluminium / etc. For tweeter frequency should be better to go higher but I think quality should always come first before frequency.

ok... actually never play around with tweeter b4
and i do not know my tweeter is dome/aluminium type

noted: higher frequency better

speaking of higher frequency, it is normal for tweeter to include part of human voice?
or it should be cover by mid range?

Vocals are covered by midrange. Tweeter only for high frequencies.

No, vocals don't just exist in midrange. Female vocals can go as high as 4khz and male voices can go as low as 200hz.

But just listing peak numbers doesn't mean a damn thing because that's not how vocals work.

While you are technically right, those are outliers and not the norm. Most vocals exist in the midrange.

Yes, true.

Which is why tweeter selection and the crossover is so critical.

5.25" means rubber surround to rubber surround measurement. So cone size itself is only 5". But there are exceptions because some drivers are true 5.25" for its cone size.

Here are examples of 5" drivers - link
