at that level of speakers ($200k--$300k+) the room and system are more significant than the speaker itself in terms of system performance. what an ’uber’ speaker can deliver is less limitations to the performance ceiling you can reach. it can allow for your sources and electronics to fully deliver what they can do.
it’s an enabler.
however, it’s even more subject to garbage in <-> garbage out than a less capable speaker. you as a system builder are more challenged to rise to the occasion. that big speaker is throwing lots of energy into a room. good and bad things can happen.
so certainly a speaker for a $100k less can compete, depends on the system and the thinking and sweat equity behind it. price/value ratio is fuzzy as to ROI as you increase the price.
