To the dude with limited reading comprehension, never said there are no good speakers with less than 92dB. What I did was answer a question, what if any measurements are important? Speaker sensitivity surely is one of them. Notice, since I actually do read and comprehend, I do not twist your words around into something you never said. I take what you actually did say and show how you completely misunderstand the message.
Anyone looking to build a great music system will do well to exclude from consideration speakers with low sensitivity. Such a speaker will limit your amplifier choices. Since the sound you get is not all due to the speaker but is the sum total of everything in the system, then things like choosing hard to drive speakers exact a price in terms of having to spend more money on amplifiers. Therefore, if you want the best sound you can get for the least money you will do well to avoid such problems. Is that so hard to understand?
