i also have a medium to large size dedicated room and have had different pairs of totem speakers during the past 5 years. if you want to play your system at loud levels, you should look at the mani 2's if you want a monitor speaker and the hawk or forest if you want a floor standing speaker. i have had the arros and the model 1's in the past and they are excellent speakers for certain applications. arros have a small 4" woofer, you probably would start to over extend it if playing at loud levels. they worked great in my 10 x 12ft den. i used the model 1's in my smaller size room with a rel sub and they were excellent. i currently use the mani 2's in my 13 x 24' room and they sound fantastic. i disagree with audiooracle about using monitors in a large room. if you are going to use a subwoofer(s), you could fine tune your room for both the best sound stage and for the the bass by placing each piece in the optimum position. for example, to get the best soundstage, it might require you to place the monitors out into the room 5 ft from the back wall. for the best bass, it might require you to place the subs in the corner, on the side walls, etc.., but probably not at the same location as the monitors. there are excellent floor standing speakers and monitors that would work for you. it all boils down to what you like and how much time you want to spend tweaking to get the best sound. good luck.
