I always thought that setting the fronts to "large" on the receiver would remove any crossover to the sub, but it seems that this is not true! I have an Onkyo DTR-7, full range front speakers and a sub. No matter whether I set the fronts to "small" or "large", the low frequencies are crossed over to the sub. This in stereo mode, where the center and surrounds are turned off. The fronts can only get the full range signal if I tell the receiver that there is no sub. Is this normal, or is there something wrong with my receiver bass management? I was hoping somebody else who has the DTR-7 or 777 could do a quick check with their receiver.
