I have heard, and liked several woofer-assisted wide band speakers. The Cube Audio Nenuphar Basis is a good example. It is not just that the woofer adds lower frequency support, the overall sound, including the midrange and upper frequencies sound smoother and better balanced. I've also heard, and liked, the other way--a tweeter added to a full-range driver. While that approach also does extend the frequency range of the system, the main thing it does is smooth out harsh peaks in the upper midrange. There are many ways to use full-range drivers, and ways to tame harsh peaks or nasal coloration or other faults while retaining the incredible speed and dynamics of such drivers.
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 ?

I get why driving speakers directly can sound better, but this explanation isn't it. IME working with 'full range' drivers over the last 20 years they simply aren't. You need both a tweeter and a sub to really make them work. Whizzer cones seem to often suffer breakups. These are easy to see if you use pink noise and spectral analysis (which is available as an app for a smartphone). |

....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* |
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... ;) |
