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

It is, without a single thought, is one of the best explained article about speaker. Thank you so much for this piece of information. ☺

I had Usher speakers with proper amplification.  I enjoyed the sound but they had to be played at a moderate to high volume to provide full sound, proper bass.    I now have Tekton speakers and find the sound full, with proper bass at lower volume.   

I finally have found an explicit discussion on the speaker. Thank you so much for the article. 🙂

Low-eff designs can suffer from dynamic and power compression. It's not possible for those designs to replicate the natural dynamic range that real music has and if you play those designs at a higher SPL level many have power compression.  If you can deal with reduced dynamic range and need a small speaker maybe low-eff is for you. If you enjoy the dynamics that real music has and want freedom from power compression at higher SPL levels and can deal with a larger loudspeaker then hi- eff most likely is best for you.
