Looking for schematic for Cambridge Soundworks P300HD subwoofer

Or if as @TLS Guy says is truly correct, that this subwoofer/bass module/whatever is really beyond hope (and should never have been sold in the first place is what I'm hearing), then does anyone here know how to contact any legal entity still in business that might have assumed Cambridge Soundworks' liabilities? If I really do have an irreparable "boat anchor" that is not actually a subwoofer, I'd like to contact them if they still exist.

The issue is not how old that actual unit is, but when it was first marketed, and that has a big impact on parts availability. The issue comes down to the fact that the components are made by robots in a sterile environment and the expense of each run is in the millions of dollars. So in general parts run out before the seven years required by law. I just had a costly unit fail at 5 years. I took it to the recycling center as they were already out of parts. Unfortunately life cycles are getting shorter and shorter, which is a big problem in my view. Then you add another issue, the boards are now made by robots using surface mount components, again installed by robots. The the third issue is that these ubiquitous class D amps, are very complicated and a nightmare to work on, even under the best of situations.

So, that is why I have so much vintage equipment, as it is serviceable and much more easily understood. I have never dreamt of touching a class D amplifier for repair, that are ubiquitous in subs and a lot of audio amps now.

That is why I feel it is very unfair to sell it to someone who will not be at all likely to get it running.

Having had a CS "sub" they were pretty useless.
