Idea – Easy Upgradable Speakers With Snap-in Speaker Elements?

The ideas is simple. What I want is a cheaper way to buy a new music experience. My idea is to offer speakers that you can easily upgrade. With snap-in elements you can do an upgrade yourself. The idea is that like the stationary PC your components age. So when you upgrade your PC why should’t you be able to upgrade your speakers? I mean I have speakers that are 15+ years old. Since they are heavy I don’t want new ones. I thought if you can upgrade the elements then I could still have the speaker box. Of course the speaker has to be adapted for such an upgrade.
