This is a relatively new driver, a 4 inch "wide band woofer" which would probably be suitable as a midrange, which is what I'm considering. Anyone have any experience or opinion? The physical configuration looks to be a smaller knock-off of the Satori MW13P with not quite as elegant a finish, but with some of the same functional features.
I'm looking for a really good 4" midrange (who isn't?) after struggling with some mediocre polypro cone drivers for too many years.
Peace,

Thanks, D, I had a look at the Wavecor. What characteristic makes it a better choice? FR looks a little peaky, while efficiency, power handling, general specs appear to be about the same. Not trying to start an argument. We all have our favorites. Just wondering if there is a particular quality I'm missing. Sound great?
I like the physical configuration of the Vifa driver with its small neodymium magnet to cause fewer reflections of the back wave. Are you aware of any negatives?
Bonus: I can buy the Vifa driver from Madisound, in my home town. I've known Larry, the owner, for over 50 years and about a dozen speaker builds. Is the Wavecor readily available?

The response peaks in the wavecor are well out of the band that a sane person would cross to a tweeter. I was simply suggesting it as another option, it is a great driver as is the NE123. You appear to have already made up your mind, but for future reference Wavecor are available at Meniscus and Solen.
Hi,
I used 2 in an MTM config with dayton RS28A. The 4 samples I got measured slightly different in 9k range and made a small difference in the modelled crossover response. I didn't get around to measuring the final result though. I think I may have gotten early production units but in any case they sounded very good. I'm not as big a fan of the larger units in the series but the 123 sound very detailed and natural.

Responding now to my own question.
Just completed a pair of mid/tweet boxes with a pair of the NE123W in each box.
After only a few hours of break-in, holy cow, these things are awesome. Such detail without any brightness. Well, perhaps just a bit of peakiness when running without an xover on the top end, so that can be easily fixed. I am using them for mids with a 1st order passive line level HP @ 400. I have never heard voices with such clarity and dynamics. I am reminded of Quads and other electrostatics.
This is just a dynamite driver.

No
It's one of the old school Vifa Mid-range drivers.
Very close to the SEAS MCA 12RC

A better driver than the PL11 IMO
