Well actually it was the governments allowing manufacturing to be taken to a communist regime and allowing low tariffs on imports for their crud (Europe and the US).   Everybody had to follow suit or die. Now we have discussions about 4 x 2.5k amps for 800 quid.  Shameful.
It's everything, not everythink!

Anyways Crown has already died due following this curve.

Does it actually have enough output to get over the noise of the fan?!!! Think my doorbell might be more powerful than that!!

Those are horrible amps, same shit as Skytec etc.  At least some of them are self-destructing type (thermal runaway) and no protections at all = when output stage fails, speakers are gone.
And those claimed power ratings are just a big joke :D 

These amps are toys really, NOT for serious use. "babby's first PA kit", as some of these are sold as amp + speaker + dj mixer kits (those speakers are same chinese shit too, weak woofer and piezo tweeters).

Ah well, you can always re-use the transformer and build something better in the enclosure when they die. Looks oversized for the output.
