PC mobo dont have amplifiers built in?
Wat amplifier do u use with elac?
My edifier didnt need such hmm
ELAC are passive speaker meaning it is like this.
There's no way to connect the speaker directly to PC without a amp.
It depend what your usage is if for gaming or movies, 2.1 will be better.
2.0 is more for clarity and mids suitable for music and recording.
Example will be Edifier R1280DBs which I used to own before.
However as it lack sub which is why I change to Logitech Z407.
Example in games/movies, the "boom" effect only 2.1 can create such effect.
So depend what type of usage you are looking at.
Home theater will be on another level but it depends what type of amp
you buy.
As no matter how good the speaker is like ELAC, you must pair with a decent amp.
