Since oval is a loose term, it's difficult to say you're wrong but AFAIK an oval can't have parallel sides unless you get really loose with the term.
Ellipses are closer to ovals than the Kef. The only reason they are not is that you can precisely identify the geometry of an ellipse which again, AFAIK you can't with an oval.
What is the difference between Ellipse and Oval?
• Ellipses are conic sections with eccentricity (e) between 0 and 1 while ovals are not precisely defined geometrical figures in mathematics.
• An ellipse is always an oval, but an oval is not always an ellipse. (Ellipses are a subset of ovals)
• The ellipse has two symmetric axis (semi-major and semi-minor), but the ovals can have either one or two symmetric axis.

so what came first, the chicken or the ovum ...

depends on whether the grass is truly greener on the other side
can we stop this now - we'll have a couple of full days to practice our witticism - a little of which goes a long ways - in a few weeks
Hi,
The B139 is a "racetrack" driver not a true "oval".
Tangband do a couple of "racetrack" bass drivers.
Its properties have not much to do with "oval" drivers,
its not a single skin, metal and polystyrene solid cone.
Oval drivers make great FR's and concentrics, but
their main problem in hifi speakers is used optimally
vertically, they increase the tweeter spacing badly.
AFAIK Spendor was the last company to try to sell
a decent range of (AV) speakers with oval cones,
and the result was a total ignominous flop.
rgds, sreten.

Hi,
Whilst NA's might call any track with only one way turns "oval",
in the UK think the Scalextric racing toy, in the basic version,
which only had straight sections, and sections of a circle track.
Hence the name in the UK, I don't know how well its travelled.

"it's a well known fact .... "
thanks, Mr Clavin
perhaps that's a cultural reference that doesn't travel well

One thing we all can agree on.. They ain't "Round"..
Jensen has a treated paper 6x9 that I've had my eyes on for a while. Still kinda old school but it has a paper tweet. Might be worth playin' with..

I don't think there is a country in the world where Cheers hasn't been aired at some point. Well maybe, but not ones I'd like to travel to for fun.
Widespread, perhaps, but even when in the same nominal language, not all widely distributed entertainment translates equally into the local cultural idioms, eh?
In my misspent youth - which by several decades predated serious car audio, 15" subs, 1000W amps, etc , the Jensen whizzer cone 6x9s were considered pretty cool. Mounted in the factory cutout rear deck locations of your standard Detroit family sedan, and using the trunk as enclosure, they could develop some reasonable bass - at least when parked for a "pop" or "smoke" - at speed on the highway, the road noise could intrude somewhat.
