Soundproofing Hi-Rise Apt?


The situation is that I a have hi-end audio system which is very articulate and low distortion allowing me to play it very loud; which I do on occasin The problem is that I live on the 19th story in a corner apt of a hi-rise.This means that none of my walls are common with the next door apt;with no sound escaping from there.But where it is escaping is my front door, with the sound spilling into the hallway.This is causing complains sometimes from management about the "loud" sounds coming from my apt. What should I use on my front door to baffle it; so the sound won't escape. I'm sure some of you smart fellow audiogoners can come up with intelligent solutions to my problem

my 2c - is not what you use, but what you don't use - don't use SUB. Those low F is what escapes your apartment the most, and not only through the door, but through the walls, floor and the celling.
You need a dual sound block. Some sort of second door that is sealing the opening to the real door, when you want to crank it up. Just applying sound deadening to the real door is not nearly as good.
Some sort of panel, (handmade?) with a solid core and carpeting or cork covering the surface on both sides. It needs to be sealing the entrance, even if it has to just butt up against the real door opening, just so an air gap exists between the panel and the real door surface, but NO gaps around the outside edge of the panel to the real door.
That will solve 90% of the door leaking sound.
