New drivers in old boxes?


I have a pair of Epicure model 3's that still look pretty good. I always thought the box was an intelligent design for its time, a narrow front baffle that widens at the back with rounded corners and a raised base ported at the bottom. This back in the late 80's. drivers are 8"w 41/2"m and a 2x4 tweeter.

Any diy'ers that could recommend drop in replacement  drivers?  I was on the human website and want to keep looking for solutions. tia Steve

JL, I did mention I was looking for an alternative to human speaker, thanks for the time anyhow. 
rodman, I wasn't aware madisound offered solutions to pre existing cabinets other than their replacement driver list so thanks for that and I will use the link. Tks Steve
Contact Madisound, with your cabinet dimensions/design details. They’ll suggest 8" drivers, with T/S parameters, that will result in the best performance, in your enclosures, based on that info. Also- tweeters and crossovers, to complete the project. https://www.madisoundspeakerstore.com/          FYI:  https://www.eminence.com/support/understanding-loudspeaker-data/
