Where subwoofers are manufactured


I'm shopping for a new subwoofer or two and have done some research online about where various brands and models are manufactured. It appears that while several popular brands are designed in the US, only JL Audio is actually assembled in the US (and yes, I know that they use parts from elsewhere). In looking at photos of control panels, I have noticed that some seem to omit the country of origin (or perhaps the photos have been altered). Besides, JL Audio, can anyone point me toward other US-made subwoofer brands? In Europe, I believe that MJ Acoustics products are made in the UK, Focal are made in France, Dynaudio are made in Denmark, and Canton are made in Germany. Are there other European-made brands that I have overlooked? Are there Japanese-made subwoofers that include 120V components? I am assuming that, based on price, the direct-marketed brands such as SVS and Rythmik are Chinese-made, although I haven't been able to confirm that based on information posted on their websites. If a Chinese-made sub turns out to be my best option, I'll buy one. First, though, I'd like to consider all available options that are assembled in countries that pay their workers competitive wages. Thanks in advance for your replies.

Thanks to all of you for these very helpful responses. Since I live within two miles of Seaton Sound’s office, I will surely check out Mark’s subs but have yet to choose whose product will get the sale. It’s good to know that there are more than one or two viable options. 
Second for Power Sound Audio or PSA, I own 5 of them, three single 15" and 2 dual 15". Very capable, great bang for the buck, I am very pleased. PSA was started by two guys from SVS that started their own company. I believe their major market is HT market. Reviews are good for their products.
You're deluding yourself if you think you will get better quality or value by buying a subwoofer that's made in the US. 
The OP didn’t ask about value, he asked who manufactures in the US.  I have a background in economics.  I fully appreciate that I can get better value by purchasing from overseas companies, but I am often willing to pay a reasonable premium to purchase from US based companies because it makes me feel warm and fuzzy inside.
