Whizzer cone drivers

bache:

I have a pair of vintage Elac S-517 8" wide band drivers that sound very good in fairly  large BR cabs with no baffle step correction.

Some owners/sellers thought the whizzer was metal, but I believe it to made out of some sort of metal-ized plastic.

I've experimented with other vintage and older Coral/R&A/Fostex drivers (with whizzers) and these (the Elac) are the ones that I kept and still use.

I also use Stephens Trusonic 80FR drivers that have a metal dust cap, but no whizzer.

The Elac's I kept were private labeled by Herald Electronics (I sold the identical Elac branded pair for $300, but now wish that I had kept them as they rarely come up for sale in decent shape - mine are like new).

Follow the money.

PS - As a DIY speaker maker, I can see how boring it may get to chase the "best" drivers all the time.  DIY is about fun and experimentation so I think some whizzers may make for a fun time building.

As has been pointed out, implementation is the big variable. Many who’ve heard it find the Cube Audio Nenuphars to sound exceedingly good. It’s considered to be one of the best single driver full range speakers currently available.
