I haven't swapped my stock drivers out because no evidence provided by the makers of replacement drivers proves that they're any better, or even as good as, the OEM. I have thoroughly tested my stock hi-fi drivers and confirmed that they are very high quality.

As for your opinion, if you think new speakers will sound better, especially because you just laid out big money for them, they will. Maybe they do sound better, maybe not.
