I may be going in a different direction here but I wouldn't say the "technology" of speakers is improving. I mean the majority of speakers today use a box, pistonic drivers, wires and a crossover, basically the same as most speakers for the last 60+ years. Now, the refinement of the materials and the implementation of these parts "should" be improving but it's not really the technology that's changing in the majority of speakers.
In fact, speakers have lagged far behind amplification (chip amps, etc...) and front ends, streaming and hard drive systems and such as far as real technology changers. Ribbons and Stat's have been around 50+ years themselves and are certainly more refined and efficient than their early predecessors but even their technology remains pretty static (no pun intended).
