help with Omnes BB3.01 CT222 crossover

juanito · 4th August 2010, 04:20 PM

Hi,
I've just got a pair of Omnes audios BB3.01 to build in small BR boxes just the same as the CT 222 satellites. At oficial web site there is a PDF with box dimensions CT222 Sat - Lautsprecher Selbstbau by blue planet acoustic
Then I've also seen at the Lautsprechershop.de web site where this kit is also, and it says that there are some crossover parts.
these the crossover components in this site:
- 0.39 mH, 1 mm wire
- 0.05 mH, 0.7 mm wire
- 10 uF ELCO non-etched
- 6.8 uF ELCO non-etched
- 5.6 Ohm MOX4
- 12 Ohm MOX4
I can't make strait link like omnes audio site

Does any body know if this is right? I mean, has any body done this kit and has the design for the crossover, or can reach how to do it from those components?
Many thanks for the help in advance.

Crossover = German penchant for filtering everything?

well the components are for two serial notch filters in a row. just send an email to the site you linked in your post. they basically are omnes audio

i'm confident they will send you the circuit layout. if not, just put together one cap, inductor and resistor (parallel) each. there should be just about four permutations or so.

the 12ohm should be a 27ohm, there was a mistake in the magazine who presented the design, and this was corrected one issue later.
