Dean. Wow, thats some mid bass suckout you have there! I had the opposite problem a hughe midbass peak at 54Hz. left me with less rumble.
Though my peak was just as bad, the effects of eq were much more subtle. I got more rumble and more detail in the upper bass, but it was not night and day when I first tried it. I find I am more sensitive to it now that I am used to the extra detail.
I'm also surprised that you're EP500 starts to roll off above 20 Hz. My EP350 has the same roll off. I guess I just get a lot of room gain here in my concrete bunker.
