Bests & Worsts Reviews from Amazon

As an audiophile who has had numerous very high end (Meridian, Cello, McIntosh, B&W, Proceed...) components in and out of my systems over the years, I can say wholeheartedly that the F-12 is an outstanding value for the $170-$200 retail price. I bought it for my 13x20x9 budget media room which is currently under construction but have been using it in my 2 channel system for kicks over the last two weeks. The low frequency extension is excellent(down 4db at 25Hz in my room) and I would consider it pleasantly musical with speakers capable of flat response at or below 80Hz (which isn't asking much). It is when this sub is paired with very small speakers that it begins to tarnish; typical of many ported subwoofers, it just doesn't play well above the 80Hz range. For example, Paired with NHT Superzeros, which fall off a cliff at about 85-90Hz, some of the "punchiness" is lost. This frequency response trough is most likely the reason why some reviewers claim that the F-12 sounds "muddy". With the right speakers and set up correctly (with a decibel meter), the F-12 is an outstanding sub for the asking price. Truly a great bargain and one heck of a warranty.
