From the review:
"In fact, Bryston says that the latest versions of their passive T series can be modified in the field for use as active speakers."
How do you mod a passive to make it active?
As Doug Schneider noted in his feature report from the 2017 Montreal Audio Fest, “Is It Finally Time for Active Speakers?,”
Doug Schneider recommended my current active speaker in 2002 and raved. Here we are 15 years later and NOW is it time? It should be IMO.
"This began as a pet project of James Tanner, VP of Sales and Marketing, who wanted a reference speaker for his own use. To achieve the level of performance he desired, the speaker developed was a fully active design."
A DIY project gone rogue eh James?
