Does anybody know anything about RCL drivers?

RCL 'made' some fairly robust budget drivers in the late 90s. I can't speak to their quality but they were pretty indestructible. Later they introduced their 'hi-fi' series of bass drivers: PP8 & PP10 with concave dust-caps. But a little birdie told me RCL never manufactured drivers - simply branded them, and the H-Fi series were made by SEAS. SEAS have an excellent reputation, and their drivers ain't cheap.

I only ask because I have acquired a pair of PP8 drivers and have cannot find any information on them.

Does anybody have any further information?
