Cool looking driver.

But I suspect the 'shrinking' contour of the phase plug might be problematic. When the cone (whizzer) moving in and out (Xmax = 4mm or so), there would be some 'pumping' effect around here...

I am not the expert but I think "equalization" circuit is not the right word. If I understood correctly, the transformer is more like a control gate for current flow. It’s more like a tank full of water. If the water level rises it flows out so the pressure at the bottom of the tank stays constant. I really liked this self controlled mechanism.

If the frequency response is accurate, I am really impressed with it. I believe that natural tone & details of the speaker depends on linearity of the frequency response (with other factors). I was looking for a full range whose response is as linear as possible. I looked at Voxativ, Fertin, Feastrex, etc frequency responses and was ready to drop a good amount of money. But after comparing 1/48 octave smoothing response of this driver to others which were 1/12 (rare) or 1/3 (very standard for most of the manufacturers) I was disappointed with exotic drivers. I believe Dayton cone & motor design is a very good quality with lower distortion and when it combines with very liner frequency response, it’s the best combinations I am anticipating.

I am going to try this driver and will post my impression. May take couple of months.
Regards.

Cool that you are going to give it a try, wish I had a higher paying job lol.. I think it probably sounds really good as Steve makes some good sound..

Mr.D (P-10) , do you have any interest in giving this driver a go in it's stock form to play and hear etc.. Seems like a fairly decent offering for the stock price and may be worthy of some of your final touches too etc..

The sens is nice and the build quality looks up there with Fostex..

An EQ circuit is exactly what it is, and what you have described.

I went to commonsenseaudio.com and noticed the baskets look just like the dayton driver. They also have alcino options. I didn't know that. I wanted to check their 12" driver out since i've been listening to the eminence 12lta and always look for drivers using the same hole cutout... looks like it's priced fairly. And the japanese coi fish and other artowork on those cabinets looks beautiful!

Could anyone confirm the family resemblance of the dayton and audio nirvana drivers?

Interesting one. The baskets aren't exactly the same -the Dayton has a circular frame where the ANs' are cut away in a quasi-square-cross-section a la Fostex &c. It's possible that they are made by a factory from the same group (in Taiwan IIRC). However, I suspect the Daytons may be better built / to tighter production tolerances. Whatever their other qualities, the AN drivers have been somewhat more variable in this regard judging from the measurements taken by some owners.

I'm increasingly liking the look of the Daytons. Ditto the new 8in Seas unit. Steve's modified P220 looks decent for what it is too.
