The transition from embedded speakers to traditional audio.

It's a pity that your center speaker is useless. The main speaker is not very good (the speaker is small and the bass is poor), but it is better than the wooden speaker and more economical.

2.

You can use the speaker at present, because you can use it, so you don't expect good results. The power amplifier only needs 40-80W.

3.

The sound consistency of two different speakers is almost the same (the stereo effect may be similar, mainly because the sound image positioning is poor and the sound quality is very bad, that is, the bass is almost the same), but it can be used generally, but it has great problems in use.

4.

If you want to change, how? The speaker is too small, so there is no bass effect when you install a big speaker.

5.

The only good way is to get rid of these two speakers, make two larger floor speakers, and buy two 8-inch (40W8Ohm) speakers +4-inch speakers for your center speaker+tweeter for the center speaker-connected by three frequency dividers; The midrange speakers and speakers are good.

6.

You can listen to music satisfactorily with an 80W amplifier.
