Very hard to fill those in electronically with EQ, I know from experience. EQ fails at such cancellation nodes. I have found that different speaker designs have dramatically different room nodes, while basic forward-firing boxes all do about the same thing in my listening room (for example, horrendous peak at 79hz which was unpleasant sounding but which could be tamed with EQ). That 79hz peak just went away when I went to an upward-firing woofer (Linkwitz LXmini), but then I got some cancellations elsewhere. Since you have a 130hz problem, about all you can do is make small adjustments to speaker position and listening position and try to create one sweet spot that's reliably smoother.
