Comparison of Dirac Live Bass Control (DLBC) and Dirac ART for all known AVRs/Processors

If you were paying attention to this topic you would know that @TimoJ is running an ART beta and has posted the measurements. These contributions have been more valuable than negativity and gainsaying.

I thank him twice already.

I thank him twice already.

And what have we learned?

Agreed. It needs to be simple interface with separate advanced settings screen. Sweep determines range of support for all speakers based on their extension with possibility to manually adjust. Level slider determines level of support for all speakers, pairs or individual speakers. Most importantly, it should have overall bass level setting as people actually have different tastes in bass levels and there is really no such thing as reference. Calibrated reference obviously exists, but varied bass levels and ranges in the mixes ideally require adjustments to calibrated level based on individual preferences. ART does everything else and all speakers support all speakers. Range needs to be at least 10hz to whatever they manage to do above 150hz. Sure some people will argue that it needs to be 5hz up .

Advanced screen, well should have more than the above, including slopes to phase in/out the support from the individual speakers.

I like your idea of sweep determining range of support and I was kind of surprised that it wasn't in the original implementation. I am not confident that I am smart enough to get it right!

It seems to me like Dirac ART is trying to do some of the things we see with regard to bass directivity that we see in Cardoid monitors like the D&D's, Kii's, and Mesanovics. Perhaps not doing it in the same direct way the cardioids cancel the back wave of bass response, but nonetheless attempting to use the sound of other full range speakers to null out the room reflections of frequencies under 500 hz or so.
