I have a pair of Totem Mani-2's that reproduce deep bass very well with proper amplification. Actually it is amazing how clean and deep they go but I find that integrating my Sunfire sub crossed over quite low so that I cant "hear the sub" adds to the overall sound of the music. If I turn up the crossover it becomes a set of speakers and a sub, much less coherent. The room size is 20x14 and that has a lot to do with bass reproduction, as was mentioned.
