great! looking forward for your take on the project.

i did some sb17 and sb15 in the past, they perform very well. i think Satori will going to be excellent performer.

regards

Passive will give a much wider potential audience to support the vendor. Quite a reasonable choice.

Why not use the Scanspeak/Peerless HDS tweeter? It has the advantage of being 8 ohms and is proven to sound great and easy for amps to drive.

My job is to do a two way with Satori woofers and tweeters. Therefore i put this project into Vendor´s Bazaar.

I have now measured the woofer and will post the results soon.
I can already say that it is exceptional wide band and clean.

Here is the frequency response at 50cm on the baffle. The other measurement is a comparison on axis and 45° off axis.

Joachim Gerhard · 10th October 2012, 12:16 AM

The response is exceptional extended, up to 15kHz and that is without a wizzer cone.
Better then some full range drivers. Off axis the response it good to 3.5kHz so a crossover between 1.8kHz and 3kHz is possible. There is a small notch at the edge resonance but you will see that this does not produce distortion.

Joachim Gerhard · 10th October 2012, 12:17 AM

Here is the near field response in 10cm. That way the effect of the baffle is eroded.

Joachim Gerhard · 10th October 2012, 12:22 AM

Here is harmonic distortion at medium volume and spectrum at 200Hz and 1.1kHz. This driver is exceptional clean. Second harmonic is the lowest i measured, third is low too.
The 1.1kHz spectrum has just 0.3% THD, the spectrum at 200Hz is around 1%.

with such a natural rolloffs on offaxis in 3khz, i think i really going to like this

cheers
