Hi! It's my first post on this forum and I would like to start a thread where I'll tell you my story of building full size planar magnetic headphones. Fankly speaking, I'm rather new in Head-Fi (but not new in Hi-Fi ) and I hope to hear your opinion (and maybe some tips!) about my work. I've started building headphones exactly 1 year ago and now I think I have something interesting to tell to the world. What are my goals? 1. To build a full size open planar magnetic headphones 2. Achieve a sound of a really high level ( my landmarks are Audeze LCD-3 and Hifiman He-1000) 3. Headphones should be ready at least for a small series 4. Net cost 100-150$ So the story begins... My first step was to make a simple planar magnetic transducer. From my point of view starting from the beginning with building a headphone is a really bad idea. I'm not novice in making non-dynamic transducer: i've already built electrostatic and plasma speakers, so making an isodynamic speaker wasn't a difficult task for me. I went to market, bought same magnets, opened Corel Draw, made simple drawings and cut with laser a few plastic and metal parts. Next day I received such result : And same speaker with one sided magnet system: If Admin will consider my post worthy I ask to move this thread to DIY forum. As a novice I can only start a new thread in "Introductions, Help and Recommendations"
