... My guess is that Gayle saw how well the Bohmer tech worked with Legacy (Legacy showed the Wavelet paired with their speakers as early as RMAF 2014) and since Bohmer is offering the Wavelet as a turnkey product, he decided to make speakers that paired even more tightly with the Wavelet. I don't know for sure, but another guess is that by giving each output channel of the Wavelet a dedicated amp to dedicated driver pathway, they can more finely tune the results of the EQ data for more specific output on a per driver level. Eikon then can sell it as an end to end DAC/DSP-Amp-Speaker solution even though the first part isn't his company's IP but touting how the speaker makes best use of the technology. On the upside, he sidesteps years of research and lots of money spent to develop it, but on the downside there's a reliance on Bohmer and their ongoing commitment to the platform. ...
This is quite a rational choice, and one even much larger outfits, like Harman of all people, do. The JBL Synthesis processor is a customized version of the Trinnov Altitude32.
I hope some more boutique speaker outfits follow suit and give players like Bohmer (on the high-end) and miniDSP (on the lower end) enough business to continue development and support.
And yes, with a channel per driver, one can achieve a tremendous level of integration, both intra-speaker and speaker to room. And many of the designer choices here go to the 'voicing' of the resulting speaker. Those of us who can do this ourselves (Ken (RUR) and I here on the MLOC, but tons of others on DIYaudio or AVSForum) know full well just how sensitive things are to even minor adjustments and to the incredible results one can get when the effort is put in. It's also a lot more fun and predictable than swapping cables or amps
