I'm afraid you are totally incorrect. Room correction is not an excuse to avoid room treatments. The best way to control the room is to use speakers that have controlled directionality.
I have never measured a perfect loudspeaker. Most are fraught with amplitude deviations and worse, no two speakers are exactly the same. Even if they were exactly the same, put them in two different locations and they will be different. Digital EQ can correct this perfectly. I find that I still have to look at measurements and make adjustments manually to get both channels perfectly equal even after the computer has it's say.
Room correction is a misnomer. It should be called speaker correction. It corrects two types of errors, amplitude and time (group delays). It is a panacea for subwoofer integration. The computer ignores the effects of late reflections and only corrects the amplitude errors caused by early reflections.
None of this can be done in the analog world effectively at all or without causing other distortion. In the digital realm it is just juggling numbers, nothing else matters.
Let's assume for a second that you can design the perfect loudspeaker. Next try to build it and you will discover that all drivers and components deviate to some degree from perfect performance. All are designed to function within limits. The more tightly controlled devices are of course more expensive. 1% resistors are more expensive than 5% resistors of the same type. All these errors compound and create a degree of variability which can not be avoided even if you buy the finest components.
I'm sure analog will persist as a niche market. People still collect Model Ts and old EV Patricians, one of the worst loudspeakers I have ever heard. But, like the cell phone, analog signal processing is doomed in the audio world. It is woefully inadequate. Granted, it is more of a challenge to put together a SOTA analog system. I can make a better performing system with less expensive components in a fraction of the time required to do it in analog fashion and that is really the key. Audiophiles on a budget (most of us) will be able to take huge leaps in performance at a very reasonable cost. Every audiophile I have done an in home demonstration for has immediately purchased a processor. It is fun to watch their eyes go wide when I kick it in.
