I will buy soem floorstanders rated from 34Hz. Yet my sub is rated from 36Hz. I know for a fact that the sub will create more rumble than the sloorstanders. But the point of this post is to ask your advice on what you think I may need to set the cross-over frequency to? Obviously I will be setting the speakers to small to ensure that the low frequency effects from the main channels (in addition to the .1 channel) are handled by the sub. Thanks.
