i would agree with the other posts. the hawks are a better speaker than the sttaf, and the forests are a better speaker than the hawks. the forest speakers have a better bottom end than the hawks but in your room, the hawks should be just fine. another option for you would be to listen to the totem mani 2's. a fantastic speaker. they are a larger monitor type speaker with dual (isobaric) woofers. i traded up from a pair of totem model 1's with a rel strata III sub to the mani 2's in my audio room. my audio room is about the same size as yours and the mani's work out perfectly. i also use a pair of totem arros in my 12 x 13 ft den. as for amplification, totem's need power and more the better. in your size room, a good choice of totem speakers would be: model 1's or rainmaker with a good fast rel or totem sub; or the hawk, forest, or mani 2. i would have my model 1's cranked pretty loud without any strain.
BTW, IMO, totem speakers blow away B&W speakers!
