Are dome tweeters heavier than electrostatic panels? Sort of kind of. The thinner mylar panels don't have much more density than the air. Tweeter domes do, but aren't tremendously heavy. We aren't talking about moving several ounces for instance. The dome diaphragm itself is measured in grams. Its weight(mass actually) is offset by being able to wind tightly around it a voice-coil which can supply some pretty intense motivation to that dome. Ribbons and Maggie style panels are in between the two. All three can be driven enough to move at ultrasonic frequencies at low distortion. In fact many conventional headphone elements are the size roughly of the dome tweeters or even larger, but don't have more than a good fraction of a watt available to drive them at high frequencies. Should we conclude headphones are too under-powered to have good detail? Your comment about heavy speakers is ignoring we can put 10, 20, 200 watts of power toward moving them. Mass alone, displacement alone, frequency alone does not tell us anything. With the right power applied we could yes move a car back and forth at 20,000 hz. It would take lots of power and to have it follow a wave with fidelity would take some kind of control system over the movement, but in theory quite doable. In practice it is regularly achieved for dome tweeters. So your thinking on this is misguided about what is important. Some electrostat mylar panels weigh little more than the diaphragm in some conventional headphones. All of this tells you nothing about which type of transducer has the most detail without looking at all the particulars. You are trying to over-simply and in the process abusing physics to reach a dubious conclusion. buonassi 1 And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain.

Actually if you look at coils of large speakers, they are quite thick and heavy. Coils have to move to push and pull cons. Weight makes them difficult to move fast. So distortion is necessary. High impedance dynamic headphones use thinner coils to reduce this weight. As you well know, the whole idea of electro-static and planar magnetic is to improve two things of moving parts: Lower-weight and no friction with levitation. Without these, planar magnetic and electrostatic don't make sense. I agree that speakers sound more natural. Using high-resolution headphones, I hear all the downside of poor recording. I can even hear of original recording media such as metal alloy tape, vinyl, etc. But I like this because with good recording tracks, I can enjoy better music. Link to comment

There are plenty of speakers that play at those high frequencies at low distortion. Whether you understand all this or not that fact: the existence of low distortion speakers capable of clean ultrasonic frequency response should give you reason to reconsider your ideas on this.

Summit Posted March 30, 2018 Share Posted March 30, 2018 All speakers and headphones are design compromises, some more than others. For example it’s generally better to have only one transducer if we look sole on the crossover filters that is known to reduce some transparency and resolution. But to make only one transducer that is optimal for all audible frequencies and that doesn’t roll of is (next to) impossible for speakers. Most speakers use different transducer for different frequencies (for example: one for bass, one for mid and one for treble) and that reduce the problem of big and heavy bass cones, for the mid and treble, which can use smaller and lighter membranes. The higher the FR the faster response is needed to sound correct. To make a headphone with just one transducer that can play all audible frequencies are easier in that regard than with speakers, but the sound it produce is made very close to the ear, so it will never really sound like playing live in a big concert hall not even the best of the best HPs. With speakers it’s crucial to set up them correct and that they can play properly with the room’s size and acoustic. With headphones the room and placement is of little importance. Still the room in the ear cup is very small and is limiting SQ. The sound reach the ear direct and the ear pad room is restricting that amount of air that can let the membrane properly push and pull with no compression, which can make HPs to sound a bit closed in and without the same image and soundstage as speakers do. Good speakers, that are set up correct in an audio playback treated room is better than all HPs I have heard, and I have heard most of the SOTAs including Sennheiser HE1. Still some of the best HPs are really good and can be a good alternative then you can’t play as loud as you want because of neighbors, family or lack of proper room to set up good full range speakers. If not accounting soundstage, image and physical bass my modded Hifiman HE6 and Audeze LCD3 are great IMO and can produce superb SQ that goes deep in the bass, have good punch, timber and are as reviling as most of the best speakers that you can buy.

davide256 Posted March 30, 2018 Share Posted March 30, 2018 I find that headphones are very useful for analyzing source weaknesses/seeing whats possible to hear in a recording, have a microscope effect on detail/nuance. But they less comfortable for long session listening than speakers. At the end of the day what matters to me is what keeps me listening to music longer and headphones are more fatiguing to use than speakers because they are worn. carlosmante 1 Regards, Dave Audio system Link to comment

Nordkapp Posted March 30, 2018 Share Posted March 30, 2018 Besides, having hair interferes with soundwave entering the ears, thus creating another level of distortion. Bald guys rejoice!!!! carlosmante 1 Link to comment

That headphones turn music into noise It's hard to find a set that works well with one's ear anatomy, let alone work well at all. What I mean by well is : technically proficient hit's the right timbre is COMFORTABLE I believe that many speaker die-hards wouldn't be as negative about headphones if they could more universally deliver on these three fronts. But the format doesn't lend itself to easy results. Every headphone I've ever heard I found something wrong with. The ones I still own, I was able to acclimate to them or correct them with EQ. I've put about 5 hours into perfecting my equal loudness contours for my focal elear and my auditory system. The result is out of this world. The timbre of natural speakers without the room problems and sound that engulfs you entirely. Link to comment
