Just wanted to add that the CNO version has a higher x-over frequency. It helps the tweeter with it's distortion levels at lower frequencies... on the other hand, the increased x-over frequency approaches the woofer's break-up frequency... it's a tough trade.

A listening test between the CNO and the original Bifrost as the drivers are the same and the x-over parts are relatively inexpensive except for the largest inductor which can be expensive depending on what type you choose.

PS: In my previous post I might have been too harsh on the Bifrost's woofer, I really meant to say it was a little better but in my opinion not enough to justify the price.

Hi nicoch46,
strange that on Troel's site he has this graph showing a much higher X-over point then 2300hz: http://www.troelsgravesen.dk/CNO_files/RC-circuit.GIF

Further in his page he shows this graph:http://www.troelsgravesen.dk/CNO_fil..._W18height.jpg

His words:"Point of crossover is 2800 Hz."

What am I missing?

I never said he didn't. Just pointing out differences between the Bifrost and CNO. Didn't know we were talking about the Ellam...

Cheers,

Furthermore some comments on the cost. At a certain level the relation between price and performance is not justified anymore. And the discussions are just a matter of taste. I also bought these units for the looks. And I'm a happy man with this system.
Everybody has to make out for themselfes if they want to spend the money for these units.

greetz,

Tim
