Popular Post monteverdi Posted December 24, 2019 Popular Post Share Posted December 24, 2019 Great review. There was very little development in driver design for decades except membrane materials. There have recently a few smaller companies developing iron-less motor systems to reduce loudspeaker distortion (THD & IMD) which is for most loudspeakers magnitude higher than any other component. Purifi has on their website some very interesting technical comments https://purifi-audio.com/tech/ They also came out with an even small 4" driver but I wonder why not something larger like 8". Larger drivers require less cone travel for the same displacement (their tech notes explain that more mass only decreases sensitivity) so using their technology could also improve drivers designed for lower cross-over points mitchco and blue2 1 1 Link to comment
