Hi I am looking at purchasing some floorstanding speakers and replacing my old bookshelves. I'm looking at something like the Klipsch KF- 28 or the RF - 52 II (or something better in the price range if any of you have better ideas). I am also planning to pair it with my 12" sub. Just wondering what the thoughts were regarding those speakers paired with a sub as one has dual 8" woofers and one the other has dual 5.25" woofers. Also, was planning on purchasing a Denon 1613 and was wondering if that would be enough for that setup. Oh ya, its a very large room too. Downstairs living room and kitchen is all one room so its very open.
