I currently own Quad 12L bookshelves, but will move those to the rear and get the 22L floorstandings when money allows, but for a subwoofer I am torn between two brands. My father has a REL subwoofer Q 201 and I love it. It is clean, and their sub-bass system is really great for two channel. But I know sunfire has more power and can reach lower frequencies. Both have low distortion levels. I was curious on anyone's opinion as to which would be a better choice, for around $1000. If there are any other brands to look at, please let me know.
