Hi, you have a fairly substantial resonance at 35 Hz or so, which is fairly difficult to address. My suggestion would be to first try repositioning your sub to see if the tail can be reduced. Assuming that it's the room fundamental, positioning at the midpoint of the longest wall might work. Two subs at the midpoints of both long walls might work even better. Whatever result you get then, add an EQ band there to reduce the excitation signal.

Thanks Mr.john. i will try and update you... i didn't use bass traps. . Will be there any change used.
Thanks
