This is an issue where you will find broad disagreement, so be warned.
I think your RT60 is fine, though it's unbalanced with that large rise below 300 Hz. One goal of acoustic treatment is for the RT60 times to be uniform versus frequency. That probably matters as much as the absolute values. So you definitely need more bass trapping. Further, RT60 values in a small room are not reliable. A room that size doesn't have reverb. It has a series of individual reflections which is similar but not the same. A small room can
have reverb, but only if it's mostly empty. So the real question is how does it sound? Is music clear and tight? Does it sound full when you crank the volume? Or is the sound dull and lifeless even at loud volume? I prefer mostly dead, especially in a small room, but others may disagree.
The room is a small HT i built about 5 years ago and have the entire lower half of the walls covered in 1" rigid fiberglass up to ear height. Front wall is 100% covered in 1" rigid fiberglass.Carpet on floor.
This is your main problem. The front wall behind the speakers is not a source of reflections unless you have dipole type speakers that send sound equally out the rear. It's much more important to treat the rear wall behind you. Further, rigid fiberglass one inch thick is too thin, and this is why your RT60 times are so unbalanced. This RT60 graph was measured in a small room very similar in size to yours, before and after adding extensive treatment (both absorption and diffusion):
Even though the decay times are short, the room sounded fabulous (IMO) when we set it up.
i have 2 corner bass traps made of 4" rigid fiberglass. Room dimentions are 5m x 3.5m x 2m
That's a start, and four inches thick is good, but you need more of those and less coverage with the one-inch stuff. If you want to add diffusers, the more usual place is the rear wall behind you rather than the front wall.
