While also expressing a preference for correcting physical space acoustic problems in physical space rather than electronic space, I welcome the addition of a well-implemented Trinnov system as an improvement for a significant number of situations. For those who find Trinnov undesirable for some uses, hopefully there will be ways to bypass certain aspects without compromising other wanted features.

Regarding room acoustics: I doubt the 997 is designed as a ‘room analyzer’, but even a consumer version of the Trinnov system does obviously have to at least ‘sense’, via the setup microphone array, what is going on in the room and make changes to a certain set of items it finds in a condition different from what is ‘targeted as optimal’. Depending on what information is passed back to the user via unit display or video menu system, one might get a hint of what the one or two worst problems are in the combination of speaker placement and room acoustics. This would allow a user to experiment a bit in their environment to determine which speaker/room modifications result in less electronic correction needed.

Regardless of acoustic or electronic treatments, modifiable passive crossovers, active crossovers, or any electronics that make ‘voicing’ and other output aspects adjustable, the last electronic item to be implemented will have ‘the last word’. As a very simple example, if you had adjustable loudspeaker voicing, and somehow you preferred frequencies from 5K to 8K to be suppressed by 6db, if you ‘voiced’ first, then implemented an electronic system that determined that suppression to be a problem rather than a positive attribute, the electronic system would likely attempt to ‘correct’ your desired suppression. So, in an instance where you might establish a target and achieve a desired acoustic output with a Trinnov system, a passive or an active crossover would still be needed to divide the frequencies in the desired ranges at the desired slopes, but other voicing aspects would tend to be at least partially overridden by EQ electronics. If the electronics allowed you to either establish a target response that included your preference or if you were able to adjust certain features manually after the automatic sensing/adjustment process, one could maintain a preference. Or one could remove their preference, adjust automatically, then ‘re-install’ their preference afterward.
