Electrostatic pros and cons.


I recently saw a feature on the program, "how it's made" on electrostatic speakers and it piqued my interest in them. I was wondering the pros and cons of them, their placement, space needs, sound, etc. Any advice would be appreciated.

Being an owner of ESL speakers for several years, and having used and reviewed others and these in many systems, I disagree with several of the generalities associated with ESL speakers. I do not find ESL inherently superior in terms of cleanness, clarity, definition, etc. In fact, in some respects they are poorer than the finer dynamic or hybrid dynamic speakers. 

ESL speakers can reveal a wonderful amount of information, however they do not reveal more information than other types of speakers. It is more so the type of information they reveal which is construed as "more". Dipole and line source speakers produce unique wave forms, and I believe that is mistakenly taken as more information. 

While the scale of ESL is typically superior to most dynamic speakers, the resolution and fine detail of the center/phantom image is not superior. It is splayed, and that is unavoidable due to the nature of the drivers. 

Bass is typically a weakness with large panels. Some manufacturers do better than others in that regard. Declarations of one brand as inherently superior to others are highly subjective, and in my case not supported by actual use. 

I do not agree that they are superior in midrange transparency. I can get equally fine midrange from all sorts of speakers, line source, dynamic, hybrid dynamic. The character of the midrange, as with all frequencies is different with ESL. I am unwilling to give up LF in using an ESL speaker, and then try to compensate by saying the midrange is so great. That is simply not true in my experience. No one should buy an ESL because they think the midrange will be vastly superior. 

I do not agree that they are insensitive to side wall placement; placing material to their side along the wall has an audible impact on the sound, and I recommend people experiment with that. 

ESL can be a fantastic listening experience - or else I wouldn't own one. But, it has inherent weaknesses, and is not wholesale superior to other genres of speakers. Anyone who tells you so is speaking from emotion, not fact. 

I am not interested in debating or arguing my perspective.
