Managed to grab a couple of hours to recap the other crossover.
Wow, really good sound, especially considering the Kefs being a small(ish) 2 driver closed box design. Very articulate, clean, natural, coherent from top to bottom. Really singing and confident. Whilst bass does not (obviously) go low it is tight and well defined. Mid and top I would describe as delicious. Very musical.
Not as much 'scale' as the Eatons or Kudos - but close.
Not bad for ~£40 so far.
Next up - clean main drivers and then woodwork.
