What is your take on high efficient speakers vs. low efficient speakers?

@Johnk. My apologies Johnk - I misconstrued your answer.  We both agree that high efficient speakers are more dynamic.

@lg1 You’ll need almost a full month in order to evaluate the speakers. The human brain can be very tricky and deceiving in the short term. 

@larryi That's what I wonted to hear from you.  You're on the right track. 

@larryi Do you hear inherent distortion/coloration from the larger speaker enclosures in comparison to smaller enclosures? Is there, therefore, any overall effect on the sound characteristic?

@larryi What would you say are the attributes of low efficient speakers?  Anyone?

jmolsberg Welcome to the  "neighborhood " - same with me - low power amp and high efficient speakers. 

@czarivey Sure, more music more noise. More filtering less noise and less music. You have to decide what bothers you more - the noise or the music?

@boomerbillone i think of efficiency in a different way. Less efficient speakers - more filtering in the design and less music. In addition, the high power amp is another problem - more filtering,  more distortion and less music as well.  I'm sure your speakers sound great, but they are different. 

Here is my take on high efficient speakers. They sound great when done right. Unfortunately, it’s not that easy to design an efficient speaker. That’s why speaker companies rather make inefficient speaker by complicating the design. Simple is better but it takes longer time to implement - that’s how I see it.

@bache With the right speaker enclosure, Tannoy dual concentric 15" speakers and many other efficient speakers extend down to below 30 hz. Not to mention that 90 percent of the music is in the midrange frequency. Who is stupid now? I didn’t want to do this to you but you made me do it. Ignorance can be a blessing. No wonder why Tannoy was the most widely used speaker in studios around the world, including Abbey Road. I guess, they were stupid too.

@bache You don’t give up easily, do you?

Would be nice if you respond back by saying - Thank you.  

@bache

Cool down!? You’re the one using derogative names and I’m suppose to cool down. What is wrong with you? Stop deflecting and projecting your arrogant attitude to others and stop waisting my time, please. No mater what I do or say, you’d never believe it, but I bet you’d not have any problem believing in QAnon conspiracies.  I know your type of personality  very well. 

@simna  With 12w and 95dp  speakers and only 190 sq. ft. room you can most probably  brake your windows in the house.

If the loudspeaker has a different nominal impedance than the volts needed to achieve a watt also changes. Some manufacturers calibrate their one watt to the different impedances. Other manufacturers stick with 2.83 volts regardless of impedance. This is why we need to be careful about reading specifications.

If we have a 4 ohm cabinet then 2.83 volts is actually 2 watts. As we have doubled the power the loudspeaker sensitivity will appear 3dB louder.

Is this fair?

Imagine that you have two loudspeakers. Both loudspeakers have a sensitivity of 100dB referenced to 2.83v at 8 ohms at 1 meter. Your black loudspeaker is an 8 ohm box and your white loudspeaker is a 4 ohm box. You put them both on a separate channel off the same amplifier and play some music. You hear that your white speaker is twice as loud. Should both these speakers have the same sensitivity in the spec?
We would argue that referencing to 2.83v is more honest than specifying a nominal 1w/1m. It makes it clearer what your input signal is.

Quick Reference

Please use the table below as a quick reference to help you compare sensitivity measurements calibrated to different values.

@Mrdecible Mrd. Does that means that the audio speakers/systems are equally great just because we like them, and how do you extrapolate the fact that some audiophiles have exponentially longer experience? Some have learned from casual listening here and there and others from numerous encounters ,with different systems, in their own homes: some have learned from the very top end systems and others not so; some can hear and interpret the sound way better than others; some have more exposure to live music and others have less; some have extensive collection of LP’s, discs or even master tapes and others no so. I hope you get my drift. The point is - although, it is great that one might enjoy the sound they hear, it doesn’t make them equally qualified to become an experts at high fidelity. Otherwise, why bother have a forum like this? I like this he likes that, let’s all be happy because we enjoy what we hear. That cannot be right , it’s got to be a better, more objective way, which I believe we  have already, but no one wants to listen.
