This is correct to the extent of my knowledge as well. Defective chinese products are usually caused by poor build quality though, not the actual parts, so you've got nothing to worry about as long as it's built in the US.All subs use some foreign parts from my knowledge. There is not 100% american subs with 100% american parts. Several are American built though.
My best two amps are Korean and Japanese //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif But you're correct, quality control matters more than anything else. Most companies simply cheap out and don't have much, thoughI've learnt to focus more on the install over where something is made. The two best amps in my install are Chinesse. It's the quality control that matters.
A wise decision. Why should it matter where the individual parts come from? I think the quality of the final assembly is more important. A bad glue is always bad regardless of whether it's made in China or Germany. And I do not imply by this that Chinese assembly should necessarily be bad either. The Chinese builders deliver what they're asked to build. If they provide a crappy product, blame the American company that ordered it to be built this way in the first place. One good example is I believe I heard Hybrid Audio and Image Dynamics products are made in China. HAT speakers like the Legatia line are pretty much among the very top level for car audio SQ and end up winning a lot of SQ completions. ID subwoofers are also revered in the SQ community. Some people don't like the longevity of plastic frame of IDQ v3 subs, but that choice was the decision of the American company ID, not the Chinese builder. (supposedly fixed in v4).I've learnt to focus more on the install over where something is made. The two best amps in my install are Chinesse. It's the quality control that matters.
