Choosing #loudspeakers can be tricky, especially with confusing terms like 'sensitivity' and 'efficiency'. In this blog, we explain these specs and how they affect your #HiFiSystem’s performance, with examples from #ATC, #FyneAudio, #Dali & @rega.co.uk: zurl.co/I3Ls #loudspeakers#HiFiSystem#ATC#FyneAudio#Dali#Speakers #HiFi #RegaResearch

Loudspeaker Sensitivity and Efficiency Explained Sometimes you'll come across people (or journalists) discussing loudspeakers, and they'll throw around terms like "sensitivity" and "efficiency", sometimes with some numbers and units flung in. But what does this actually mean, and how much does it practically matter?When people discuss the efficiency or sensitivity of a speaker, they're really trying to come up with a way to describe how loud it will go, for their amplifier. More technically, what they're really asking is how to reason about the relationship between acoustic power output and electrical power input.If we deliver the same amount of electrical power into a very sensitive speaker, that speaker will move a lot of air, and our ears will detect that air pressure change, and it will sound "loud". If we have a very inefficient speaker, the same amount of power applied will result in less air https://expressiveaudio.com/blogs/audio-advent/loudspeaker-sensitivity-and-efficiency-explained
