It really depends. When I moved to an apartment in Manhattan from a big house in the suburbs, I had a similar concern and I ended up disposing of a lot of stuff that I later regretted. You can always sell/swap it later when you know exactly what you are facing. For example, my building is constructed of reinforced concrete and no one has ever complained about low frequencies, not with my old monster subs and not with my big rig now. So, don't presume or limit your options until you have to.
Good luck.
