I have some Verit Heritage speakers I bought around 1978 or so. The drivers no longer work (except one tweeter still tweets weakly ;-). The cabinets are still OK and are pretty solid. I'm wondering if I can just put in some new 8" woofers and 1" tweeters and be able to use them again. I assume I'd have to buy a matching set of drivers and crossovers, but I'm wondering about how to know whether the drivers will work with the existing box size, how much fill to add, and how long the 2" port should be. I think this approach is sort of backwards from the norm, where you select drivers first and then design a box for them. But can this be done?

Thanks!
