In Reply to: RE: DSP-based active speakers are different from conventional active speakers. posted by Kal Rubinson on March 19, 2020 at 05:33:35
Kal, what are your thoughts on the differences between the digital processing and speaker design of the Kii Three and Image1? They both appear to make it relatively straightforward to correct for the acoustic anomalies of a typical listening space, but I don't fully understand the technical aspects of either speaker.

I am loath to comment because, although I am quite familiar with the D&D (as well as the B&O and Kii), I have no hand's-on experience with the Eikon Image1 and their documentation is lacking in substance.
I did see and hear it a bit at RMAF in 2018 and was disappointed at the need for the external processor/controller, the plethora of (analog) interconnections and, iirc, the need to upload measurement data in order to download correction filters. None of that, of course, says anything about the actual performance which I could not judge under the conditions.
I thought the external processors were a benefit in that upgrades would probably be easier to implement. The need for analog inputs could be potentially be eliminated (other than tape and vinyl) if Eikon incorporated digital sources in their processor. Perhaps something similar to computer expansion cards. But that's asking an industry that prides itself on individuality to agree on a common protocol.
Having uploading measurements makes sense in that they wouldn't have to keep thousands of processors current. Cloud computing makes sense in this case.

1. The processor does accept digital inputs but outputs analog to the speakers which are, physically, 4-way analog speakers without crossovers.
2. The original processor I saw looked like the Legacy Wavelet processor and I wonder how the snazzy new one differs.
I guess I missed the nuance of what was being described. The Eikon website has this entry in the specs for the controller/processor: 8 balanced output XLR channels. So the signal path to the onboard amps is external, requiring four interconnects to each Image1?

I suspect it is a single snake cable per channel with an 8-xlr break-out on each end.
