And you didn't make it clear whether your configuration is for games, movies or music? Now the low-end X-FI is licensed in 400 yuan (it is not easy to sell, the manufacturer stopped production, and the general manager of Guangzhou told me). Unless you buy the top-end X-FI, I don't think it is necessary to match it like this. After all, you have to consider your sound source and the level of the box.
Since you bought 2.0 speakers, most of them are for music.
Tell me about my feelings: I'm A2ZS from LOGI Z5500 (for the game). I feel that in the case of coaxial connection, the bass is heavy enough when watching movies, and the 10 inch subwoofer is sharp enough, but the sound is a bit lacking. When playing games, you can only use the virtual 5. 1 to enjoy EAX and other effects. But if you are listening to music, these multimedia speakers and sound cards are not satisfied, so put the idle B&; W took it out to listen to music again.
If it's for music, I believe your configuration is not very effective (unless your ears don't mind). If you really want to give up, buy a better bookcase and power amplifier, use the optical fiber or coaxial output of the sound card that comes with the computer, and give it to professionals to decode and restore. As for the power amplifier, just buy about 3000 yuan like Tianlong (with DTS decoding). The choice of box should consider the size of your room and the matching of your amplifier (although Tianlong's amplifier is enough to push), and you can't blindly covet the size of the unit. The key is that your ears can enjoy it. Building your own audio-visual system is really a pleasure.
