The Sound of the Satori Monitor ?
Very clean, open and dynamic.
Soundstaging is great too.
When it is on the recording and your system is good quality to sound images are free from the speakers and free floating realistic in space.
focus is great too because the Satoris are made to close tolerances. My pair matches very well.
I can not say much about the Kairos. Maybe Jeff B. jumps in to help you.
I mostly use parts from Mundorf.

Mr Malty, crossovers at this level of performance are precisely designed to work with the specific front baffle dimensions of the design. Due to the baffle step effect, reducing the width of the baffle around the tweeter will cause it to roll off at a higher frequency than designed, creating a dip in the system FR. Might not be audible, but I personally would not mess with the baffle dimensions or angle. The compound angle joints on a box design like Watt calls for good woodworking.

I think you'll find the kit xo parts quality more than good enough.

With a single sub I would build them as ported so the crossover can be as low as possible. You can close the port later with a sock if you want sealed alignment for stereo subs with higher crossover freq later.

Thank you. One question about the port. My sub measures very flat until 20 hz. And about -3db at 17. I bought it years ago when I upgraded my rel stentor. Are you sure I cannot run it sealed? Thank you.

My apologies to Joachim for this highjack, but since my Kairos has been discussed here and since I have receive a number of emails and PM's specifically asking if my Kairos can be built on a tradional flat baffle, I wanted to post this update.

As most of you are aware, the crossover in the Kairos is designed specifically with the baffle slant and its offset factored in achieve the time and phase relationship of the Kairos, so the same crossover can not work with the drivers on a flat baffle and achieve flat response.

So, in response to all of the emails I have completed a crossover design for the SB Satori drivers for use on a flat baffle and have sent it to Mark at Menicus.

I used the identical cabinet volume and tuning as the Kairos except without the slanted baffle. Of course, this changes the time alignment to be more like we normally deal with and as a result I ended up going with a more standard LR4 In-phase asymmetrical acoustic crossover with excellent phase tracking and a deep reverse null.

The crossover point came out to be an identical 1.9 khz and I used the measured response of the Kairos as my target response when modeling and was able to hit it pretty much on the nose. So, the new speaker has the identical on-axis frequency response and crossover point. It would have better vertical lobing, but with a lot more phase rotation. (I wonder how much different then sound? Or if you can even tell the difference. I can't really test them head to head to see).

The new version has a different name to avoid confusion. It is called the "Adelphos" , sticking with the Greek theme, Adelphos means "brother or kinsman" to the Kairos. Mark will price out this kit as well for anyone who rather choose the standard flat baffle over the Kairos special time and phase characteristics.

I may soon be working on another kit using the Satori woofer but with a different type of high-end tweeter. Details to follow.......

Jeff B.

No problem. Even if the Kit i have designed sells in the hundreds for me it does not make a difference. Head to head testing of your designs may be a thing to do Jeff.

Joachim,

Do you have any updates on the availability of your design as a kit (including the enclosure)?

Cheers!

Firstly, great thread; very interesting with a wealth of not so obvious speaker building information.

How does the Satori speaker compare to the Anima speaker. I am quite familiar with the Anima as I've actually had a pair in my system, albeit briefly. Of course, the Satoris are a bit bigger, but how do they compare tonally, and at low listening levels?

That is subjective besides what you already mentioned.
The Satori Monitor is bigger, plays deeper and louder.
