if you want better speakers, sell the def's and buy something else. I could go into all the reasons it is not a good idea but pretty much there is a 100% chance that anything you 'drop in' will give you worse sound regardless of driver cost.
Upgrading the drivers on my old Definititive bp8
These where bought back in the mid 90's and was wondering if anyone has experience with upgradng the drivers on these. What brand and model do you recommend? I wouldn't need direct drop in, so if I need to router some material out to get some drivers that will make these speakers shine, I'm all over it.
