im looking to replace the speakers in a set of headphones i have.. and well, im looking for the absolute best sounding speakers to put inside them to replace the old dying speakers... theyre 40mm speakers now.. might be able to fit a 50mm in there...
so whats the best construction/technology? i hear a lot about neodymium and other technologies, what would be best in this category?.. also frequency, impedance, sensitivy?... im looking for a set of bare speakers i can buy probably online, and solder in place of the old once and im looking for some advice on what to use and where to get them?.
