Planning to try this later.
If got local product similar to this then I will choose the expensive ones.

Maybe will get this.

Subwoofer is important for EDM and action movies.
Without it also fine. If want like boom boom then subwoofer is needed. Like shooting, helicopter, explosion scenes.

Wait for Lazada Birthday Sales on 27th March 2022 to order.
You can test without T5. You can add the subwoofer anytime.

If really not urgent maybe can wait for 11.11 sales.
I find that 11.11 sales have the best deal for s3000 pro.
Do buy from Lazada as Lazada might have Bonus will be back this year. RM100-10 bonus during sales offer.
You can get s3000pro below RM2K during offers.

You can ask Zoozoka as he also using S3000 Pro without T5.

Actually can connect.
But if want to connect also can.

Actually without sub also good. It depends on your preference.
The reason why they said not suitable because due to no sub out. The only disadvantage using subwoofer together. The only input is only RCA Input.

Meaning that if you connect through Bluetooth or USB or optical or coaxial as only speakers works. Subwoofer need to connect through RCA Input. That's one of the main disadvantages.

I copy the sentences from AVFORUMS.

Just chat with edifier Lazada after purchase.
I discuss about T5 and S3000 Pro.
Contacted the seller which product got sub out.
I asked about how to set treble and bass.
Then also T5 LPF settings. Then I mentioned that I need to buy to pair with T5. They straight away said can use bypass function to use with T5 together with S3000 Pro. They never stop me from using after I placed order. No issues to pair but need more cables.
Without sub no issues. For me wanna add to try.

Source to T5 then T5 to speakers.
Agreed. Also wireless connection to each other.
Can avoid thicker connecting cable to connect from right to left. S3000 Pro do have USB port as well.

S3000 Pro short of one port for RCA input.
S2000 can connect two RCA input.
We watched movies. We have to adjust the scenes with singing. Quite loud enough.
