Elliptical Speakers. Why Are They No Longer Used in Hi-Fi?
(restarting this thread as it was accidentally deleted, previous contributors please feel free to repost)
Generally, manufacturers don't use elliptical drive units in Hi-Fi speakers. They were very popular years ago. Ellipticals have much going for them, less obvious cone colouration, broader operating bandwidth, and the narrower chassis for a given cone area allows slimmer cabinets to be designed. It's all good news.
Perhaps they fell out of favour for being regarded as 'old hat' or 'radiogram speakers' years ago.
Mordaunt Short were that last maker to employ them in quantity that I can recall.
No doubt there may be an obscure design or two out there using ellipticals, but I can't think of any.
