I have heard, at a local AC'rs place, a sub kit of theirs - I think it was the Titanic 10.
Sounded good, and for the money a good choice.
I get killed with border fees and taxes etc when they ship to Canada though, so I tend to lean on Creative Sound Solutions in Canada, or Solen for my goodies.
I have also ordered from Danny at GR Research, and Kevin at DIY Cable.
