Im confused. They dont actually do what the measurements show they do? Multiple sources have shown the same high frequency performance on and off axis.

You're saying that the 10F/4424G00 has the same off-axis performance that a 1" or a 3/4" tweeter does?

Looking at the Blue (on), Green (15 degrees), and Red (30 degrees), it compares fairly well to 1" dome tweeters.

Here's a Seas 27 TAFNCG for a quick example

Yes, I've worked with the 10F, the 8ohm version though.

The difference between the two drivers above will be very audible.

SEOS 12, DE250 (7.5 degree increments). Outside of the outstanding CD response, nothing special or extended about the high frequency extension. Arguably worse then the SS...

I'll definitely test the SS out before I plan a mega build around it, but I'm still not seeing where its performance is poor.

It isn't a poor performer, in fact it is excellent. The dispersion is only slightly more directive than a typical 1" tweeter, and most of that is beyond +/- 30 degrees.

I remember JohnK questioning his own original Note's design making use of the Neo 3 PDR.


Now as far as sound quality.. I believe that Planet 10 didn't quite think that they sounded as good as some of the smaller Fostex drivers, but I'm even less sure on the conditions that formulated that opinion (..if indeed there was one).

That's what I was thinking. My intended use would be crossing 500-1khz to some kind of serious woofer setup. Outside of a huge waveguide, this looks like one of the only drivers well suited to the application.

Pretty much a "FAST" design.

You should probably base the woofer's crossover in conjunction with baffle step loss. A more narrow baffle, higher effective crossover freq. (..and vice-versus).

If you need a bit more "air" because of increased dispersion beyond +/-30 degrees you could always add-in a rear facing tweeter with a very high freq. high-pass filter.


You might want to "ping" Dave/Planet10 on this and get his thoughts on this driver and other similar drivers as well.

Where these 4" drivers will fail as a "tweeter" are distortion and stored energy. Just like any other full range of similar size.

I forget my history but can't stored energy simply be EQed out since it is linear distortion?

Also, with the two charts Jay provided we can see that the SS is 7 dB less intense than the 1" tweet at 10 kHz. With the following waveguide at least everything can be EQed flat with matching off-axis.
