Great. I was also at one concert that had more bass and volume than was necessary. 1983 or 4, Peter Gabriel at the Richmond Coliseum, a large outdoor amphitheater, the Summer home of the Cleveland Symphony Orchestra. Gabriel crammed a stadium sound system into one of the most efficient outdoor venues in existence. The bass drum kicked you in the stomach so that I could feel the abdominal wall shake. I had to stuff rolled up napkin in my ears. I did not get that abused at a Nine Inch Nails concert.
There is a visceral component to live music. You do not just hear it, you feel it. This is one aspect that makes live music exceptional and it does not take as much volume as you would think to create that effect in a home system. It takes accurate bass flat down to 18 Hz at the listening position not one meter in front of the speaker, the rating the manufacturers give you. Big venues breath. You can tell you are in a big place with your eyes closed. This happens at very low frequencies.
Most people expect a home HiFi system to sound like a home HiFi system and as long as they can listen to music played back cleanly they are happy. I expect my system to sound like the venue the music was recorded in, (With live recordings which I prefer) with all the visceral content intact. This means that I have been unhappy for decades and are always expecting the next improvement to get me closer to that goal. You are not a true audiophile unless you are unhappy with your system or lets say, not entirely happy. It is that visceral component that is hardest to get right. Maybe imaging is harder. I guess it depends on what day you talk to me.
You have one subwoofer. When you get a chance buy another of the exact same model and put both between your speakers. You can get a two way crossover from MiniDSP or dBx for not much money. IMHO the low pass filter found in most subwoofers is a half baked way of adding a subwoofer. Cutting the bass out of your main speaker is so beneficial it is hard to over state it. You will notice right away that your woofers seem to remain stationary and the sound is less .....stressed. You will also notice some of that visceral sensation even at modest volumes.
