It's interesting to ask why classic designs don't appear to include active designs.
I'll speculate that this is down to advances in amplifier design lagging compared to the drivers, and specialist manufacturers dominating the leading edge during the 60s and 70s. You need vertically integrated companies that can excel in a range of technologies to develop active speakers, or you need modern supply chains to be established providing electronics to OEMs.
When the best amplifiers are valve based, you aren't going to get active designs unless you want to set fire to your home
