Whizzer cone drivers
According to my expirience as speaker designer , i am wondering why so many companies still making loudspeakers with wizzer cone drivers and so many guys fall in love with this products choosing small paper cone as a additonal tweeter prefering high quality tweeter made from top quality components.Yes, no crossover ( capacitor) , but still ?
Oh, btw...toss some cotton 'fluff' into the cones, it tames the 'cone honk' I notice from an open cone....the 'Rudy Vallee/megaphone' quality that's the main drawback.... That, and the cone really needs to be flipped vertically as it radiates more at your knees, but that's why the old Ohms work so well... ;) |
....while drilling about for details and examples of omni approaches of the past and present to put some sense into my Walsh project, I ran into this: http://www.roger-russell.com/omni/omni.htm#onea If you shortcut to the Hegeman 1a and the Eico portions, these ’whizzer variants’ were simple enough for me to half-tush a pair diy out of curiosity. Surprisingly enough for something so simple to accomplish, it’s interesting to make a whizzer cone respond in an omni fashion, albeit vaguely directional. The hardest part is ’rolling’ a cone with a 45 deg. angle in a lightweight enough material to not hinder the drivers employed, but... No static 'over driver' cones. either.....and not as effective as a full Walsh omni driver. but cheap thrills on the quick. *G* It’s (imho) the only application of a whizzer cone that actually makes a difference. Forward, into the past....*L* |
