As a proponent of active speakers congratulations on the nice backlog at the time of your crossover's production release!
Here is an interesting article featuring Bryston on the subject "Is It Finally Time for Active Loudspeakers?" http://www.soundstagehifi.com/index.php/opinion/1067-is-it-finally-time-for-active-loudspeakers
And follow-up from a reader http://www.soundstagehifi.com/index.php/reader-feedback/1071-a-paradigm-active-40-owner-on-active-speakers
When I worked at a HiFi shop it was at a long time Paradigm dealer and they recalled how much better the active versions sounded compared the passive versions of the same speaker model. And how they could not sell them. As the article notes "audiophiles won’t buy ’em, because audiophiles don’t buy active loudspeakers. And non-audiophiles won’t buy ’em because non-audiophiles don’t buy $2000 loudspeakers.”
The article touches on the tension between the simpler systems possible with speakers featuring built-in amplifiers vs. audiophiles' desire to optimize our systems to the Nth degree via mix-and-match every big and little component. Bryston's offerings allow the large sonic benefits of active and the lovely complexity we hard-core audiophiles enjoy yielding max performance of a separate component system. I also believe that when companies demonstrate the longevity and consistent very high performance Bryston has many audiophiles make the (smart) commitment to single make systems source to speakers, as seen in the pics above. Adding active capable speakers and matching crossover allows yet another step up in performance for a 100% Bryston system. In his article Doug Schneider describes the result "Their all-Bryston system in 2017 reproduced incredibly deep, tight bass; beautifully clear, detailed mids; superbly extended highs; and a soundstage as awe-inspiring for its width as for its depth. Rarely, at any audio show, have I heard a system sound so good
Now as a bit of historical trivia checkout this page from a 1969 JBL catalog courtesy the Lansing Heritage web site. Yes in 1969 JBL recognized the benefit of powered speakers and offered both passive and as they called them 'self energized' versions just like Bryston in 2017. We audiophiles can be rather odd in the ways we pick and choose different bits of engineering to spend decades perfecting or resolutely ignoring.
