I ordered one of the LV12R a couple weeks ago for my "budget" living room 2.1 system. Large open space, wanted something that could give more extension and output than my old TSC 10" sub. I've been very happy with the Rythmik F15s in my dedicated HT setup and decided to stick with the brand, despite the large number of competitors in this space. The LV12R is not obnoxiously large or heavy, has the servo amp feature with adjustable damping, and offered a matte vinyl finish (not interested in fake oak). As far as comparisons go, <$600 is quite different from <$1k. I've bought and sold quite a few subwoofers in the last 10 years, and at this point in the game I'm looking for a product with decent value that is made by a company that hopefully won't be shut down or bankrupt before the warranty expires...
