Clarity, imaging, detail, presentation... in dynamic speakers, should be better with contemporary mid-level offerings. Drive units' materials have evolved, so have design and production processes, making once expensive models more reasonable.
Also cross-over components have improved. Last, computing power & design s/ware have improved and prices have gone down there too. Overall, many contemporary speaker manufacturers take phase, distortion, and transient/amplitude characteristics into account, and can model the speakers using test equipment that was once untouchable...
Not least, today's speakers are more efficient than many older models..
On the down side, the basic design principles have hardly evolved; as a product, many commercial speakers are still quite expensive especially if you want a true full-range
