I expect any ongoing research following Dr. Toole's will be more elaboration than refutation. This is what happens when scientific research is so well planned, executed, and reported.
So far, there have been no pivotal additions to speaker technology since Toole's latest edition report. That doesn't mean there never will be. Further, there have been few pivotal transformations in architecture and interior design since Toole, and much of his research involved practically realizable rooms. That doesn't mean there never will be.
So, to date, Toole's work seems settled research and foundational to ongoing audio reproduction efforts. That said, his reports are not some antiquated religious document that can never be altered or fine-tuned. Perhaps, someday, there will be a sort of quantum treatment to sound analysis. Or not. Quantum physics hasn't replaced classical physics, for example. Quantum just takes a closer look.
Toole's agency's studies of the preferences of human test subjects and the statistics of that are bedrock. They should be required reading and review for anyone who does subjective ratings involving test listening, yearly.
If a reviewer hasn't read and understood Toole, I would doubt their ability to accurately review a clock radio. -Just one man's view.
