Does any one know if the Ref Model One can be "upgraded" to the mk2 version by changing the x-over or modifying it?

The One-Two also seems to use a different uni-q mid driver compared to the mk1 too.

Was the One-Two a big improvement or more marketing?

Model One had a small single woofer coupled cavity utilising part of the volume in a largish cabinet, which acted as an integral stand.

Model Two was a dual woofer coupled cavity with anti-vibration coupling, utilising the whole cabinet volume.

Hi speakerguru, I meant the differences between the one and the one two.. Confusing? Err kinda

Original Model One, Two, Tree, etc series

Second "improved?" versions comprmising of the One-Two, Two-Two, Two-Three and so on.. Which had changes to the x-over according to that page to make them more "neutral"

Model One, Two, Three and Four were the last speakers I was involved with before I left for pastures new. Obviously any speakers after that would be inferior Cool

I know nothing about One:Two, etc.

Woo got the drivers back today... One thing to note, if any one looses output to the LF driver it could be the big inductor that's got a dry joint.
This happened on both of my speakers.

I haven't put them in the living room yet and just listening through my Audiolab stuff but so far very nice neutral sound, good mids etc Just wish the bass went deeper also they're a bit on the short side, to listen on axis I'd have to be sitting on the floor
