Default Kairos Crossover

R Hi everybody.

I have SB Acoustic Satori MW16P-4 (4ohm) and the TW29R Satori tweeters. I was using these in my car and have since removed. I am now looking to build the Kairos Kit from meniscus. however crossover will need to be changed. I am looking for assistance on new crossover for these speakers utilizing the enclosure from the Kairos. Any help would be appreciated, thanks.

What's wrong with Jeff's very carefully designed and executed crossover?

Hi,

You need to use FRD tools, or something similar, to simulate your x/o and your drivers.
The Kairos PDF manual has all the information needed to simulate its x/o design.

rgds, sreten.

assuming it was designed for 8 ohm driver not the 4 ohm which I have. Would it be possible to adjust values for inductors and caps

Didn't Joachim Gerhard's similar time-aligned Satori design use the 4 ohm driver?

I think the guru clone stepped baffle version used the 4 ohm, but the actual SB Kalasan monitor used the 8 ohm. I would buy the 8 ohm and build the Kairos as designed.

Interesting. Joachim redesigned for the 8 ohm bass and called it the Kalasan 2.

http://www.diyaudio.com/forums/vendo...onitor-66.html

He also reckons it will work with Jeff Bagby's sloped box.

I don't see much alteration apart from the tweeter Fs correction and some level changes. Looks an easy project, which you could mix and match and tune by ear with either the 4 or the 8 ohm. Ideal diy territory.

Well, the LATEST version!

Obviously a moveable feast. TBH, the SB Acoustics Satori 4 or 8 ohm 6" driver is pretty neat. Tempting people into all sorts of low-slope designs.

Gornir does the 4 ohm bass version here with a different tweeter
www.audioexcite.com Satori Two Monitor. Last below.

Joachim gets excited about his 8 ohm Kalasan 5 bass version. Below with some midrange dip.

I think I get the idea. Obviously hard to mess up entirely. Worst comes to the worst, you could design a steeper slope.

I never get excited. This world is too dumb for me.
