Your equipment does its best to reproduce your sources and that was all it was designed to do.
unless your room is a sphere, lower frequencies are going to reflect out of the corners of your room at different speeds and it can make your bass sound muddy. That is just one reason all rooms need some help. What I’m referring to here can be helped by bass traps. There are dozens of other issues you can have. Most people don’t have all of the, but everyone has some.
All the best.
