Here is a paper Dr. Toole wrote recently.
http://www.aes.org/tmpFiles/elib/20150911/17839.pdf
I just skimmed it. It looks like a summary of past research. It also offers some conclusions about places he thinks the research should go. My take-away here is that Dr. Toole believes that in room measurements below the Schroeder frequency are needed and DSP to correct minimum phase bass issues below the Schroeder frequency are very helpful. However, Dr. Toole seems to dismiss the notion that a rolled-off HF target curve is needed. That's not been my experience but that's what his paper says. Dr. Toole is also very critical of any attempt to apply DSP above the Schroeder frequency. He doesn't think time windowing techniques work well above Schroeder. My experience having used several different softwares is that this varies greatly from setup to setup. So, there may not be a universal answer. But I believe that smart DSP above Schroeder can be very effective.
I don't think Dr. Toole anti-DSP. IME, the best target based DSP I've used is very careful to treat measurement above the Schroeder frequency differently from measurement below. Of course, windowing is the special sauce in all fancy DSP softwares. This is where the debate rages. What is the appropriate, if any, windowing which should be applied to get the best psychoacoustic response from the listening position?
