Hi Troels,
I thought I would drop you a note and tell you that I finished the project and I'm pleased.  I modified the crossover to suit my room and my preference.  The change was substituting a 4.7 Ohm resistor at R2.  It flattened the mid-range hump and made for a smooth downward slope.  No more edginess to my ears. 
I put the build up on DIYaudio.  Feel free to take any of that (or none) for your builder's response.

You might consider offering this version as the B&K sku ;-)
Thanks for your patience and suggestions.
Mike

Hello Mike, thanks for pics and comments. I have to mention that the resistor change you made will produce a significant decline in the midrange producing a hammock frequency response. Not really hifi, but possibly suitable for lesser quality recordings - and personal taste. Regards, Troels.
