Query: Great sub for the money

I wasn't looking for a subwoofer that could rattle the walls and break the windows. I'm not a gamer or into hard rock, metal, etc. I listen to a lot of classic jazz and wanted clean accurate bass reproduction at relatively low volume--I'm over 60--and at a reasonable price. I wanted a unit that would augment soundtracks on DVDs without overpowering the other channels. I think the PSW-10 fulfilled all of these criteria. It even arrived sooner than I expected. I'm quite happy with it.
