To best treat that range, you need absorption about 4.5' thick. However, given that you have a null at 86Hz, I assume you don't have enough broadband absorption in general. The advice that everyone gets is you need as much, and as thick, of absorption you can manage. Without knowing your room size and how much, if any, treatment already is there, I can't tell you precisely what you need. I use 20 4" 8lb mineral wool 2x4' panels and 9 31.5"x4' super chunks made from fluffy and my room is decent but not perfect. You can use that as a guide.
Also, if you haven't, please read the stickies.
Thanks.

Stickies are the threads that are permanently locked to the top of the front page of the acoustics forum. (they're "sticky" because they don't get pushed down over time) We ask people to read through those before asking questions since they contain answers to many of the commonly asked questions and prevents us from having to repeat the same answers over and over. If you have further questions after reading through those, just ask.
