It can be difficult. You don't know what you are missing if you can't hear it.
I had a nice pair of ADS L-810II speakers that I purchased new in the late 70's. They were a "full range" speaker and really nice example for that era, still in use by my little brother. With my present, way short of state of the art system, I am frequently shocked by low frequency information that I never knew existed.
I presently have a pair of KEF R3 Meta bookshelf speakers with dual HSU subs. Those subs are essentially flat to around 20hz. I hear (and feel) low frequency music that just was never there before, even on decent headphones,
