What are the best modifications that can be made for these speakers, i.e change the polydome ( but to what? ) . I do not want to get into changing any internal wiring since I would screw it up. Are there any "drop in" speakers that could help. Stupid question but I would like to know if anybody has tried something different( esp. for the midrange-Bass & Treble seem fine). I am bi-amping with Yamaha MX-1000 for the bottom & Onkyo M-508 for the top.
Thanks
