[QUOTE="Air, post: 846092, member: 15182"] I was just thinking about a factor that could also influence the impact various crossover frequencies of "sub" to main system and why some prefer a higher crossover point. Most systems, at least 2 way systems suffer from floor bounce, the comb filter effect, that is a function of the distance between the mid-driver and the floor and cause a deep null =/- around 150Hz. It is almost unavoidable with 2-way speaker in typical setups(Audio Note circumvent this effect by corner placement at a cost of other factors). In a 3-way(or to a degree a 2.5 way) the challenge can be better managed with careful driver placement in the design. It might be that those who prefer a higher crossover frequency for a "sub" actually mitigate this effect with the sub being close to the floor and sometimes back wall. The sound of the system will definitely have more punch. I still think that such an arrangement is not ideal because of other nasties that might occur in the critical midrange but the pro's might for many outweigh the negatives. [/QUOTE]
