A Guide to Bass Management (Part I)

Ezyl, I don't think you have anything to worry about with what your experiencing. The purpose of setting a speaker to small with a crossover is to enhance the overall sound of your system when said speakers can't produce the proper SPL at lower decibels. What you want is for everything to blend together seamlessly. So the fact that you can still hear a faint sound coming through speakers set to "small" won't really be an issue IMO. Especially since you can still hear the sound at proper levels on the sub. Now if the "small" speakers were still trying to push the sounds at full volume that would be cause for concern. It could also be that the test tones your playing are not pure and the sounds actually have frequencies above to crossover setting.

If it's something that you can't hear during movies and music then I definitely wouldn't worry about it.
