Hello, I can't answer your first question regarding equalizing. My suggestion is to go to Real Traps website as it has some of the best info around regarding the use of eq and room treatment. I also think he has the best bass traps, which is what you need. Don't forget two important things, first is that bass traps are most effective in the room corners, it is the place to start then work you way around the room. Because point number two is it is all about coverage, to be very effective. One bass trap, don't waste you money. Two bass traps in the corners is absolute minimum. If you can treat all four corneres its a good start. Room acoustics and bass trapping is the biggest revelation you can have if done properly. I believe all serious audiophiles should have a treated room and hopefully new audiophiles do this before buying equipment so as to really hear what they are buying.
