WTB: Osborn Epitome bass units

Hi all. I'm on a no-rush lookout for the optional bass units Greg Osborn builds for his Epitome speakers.

I' m happy to wait, and I'm in Melbourne. I'd also like to match them to my speakers, which are a pale finish (which are the light coloured Tassie Oak).
Fantastic! Enjoy those tunes! Mat
