Below 100Hz your room plays such a significant role as it applies to room modes, sub placement, size of room, etc. that applying a dedicated correction to the sub before DRC is the way to go because the DRC will then incorporate these corrections into its own calculations by taking into account the delay caused by the bass management's processing. But if you move your subwoofers you'll have to do both all over again.Can the situation with these prepros be improved in systems that use subwoofers with their own correction, JL Audio or Martin Logan for example, by apply the correction of the sub before these DRC systems are used?
