Well what I meant is that there will always be new versions coiming of the crossover network and the drivers.. woulnd't be nice instead of selling your speakers or sending them back in an exchange program simply have an upgrade kit for those who really want the latest version... changing a drivers is not a problem the real problem is acessing the crossover network, so having an access panel and relocating the crossover board on the bottom of the speaker would be fantastic also simple to exchange in case of a faulty board
