Hi everyone, I have one pb10-nsd and just placed an order for a second one. With the backorder it should be here in a few weeks. I have never had two subs before but I know how to hook it up and everything. The problem I think I am going to run into is big peaks and nulls that I am already seeing with one sub. I am planning on stacking them. The EQ's i have looked at are the Beringer feedback destroyer which has gotten some good reviews and the Velodyne sms-1. Im pretty new to HT but would be willing to learn how to manually set one up. I also see that the back of the Beringer only has the XLR inputs? what is that and how would I plug in two subs? The REAL question is; Do you think the Beringer would be too complicated for a newbie to master or should I go with the easier auto cal of the sms-1?
