Welp I downloaded that track and this is what I have found.
1. The PC speakers at work told me there was no bass in the track until I craned the 35hz slider up and I could hear distortion several octaves over the freqs that were being played.
2. So great, the studio rig will play it right? Played the track through my studio monitor set up (5 1/4 JBLS tops with a KRK sub). I heard some bass this time but then I also heard a ton of air and looked down to see my sub trying to play something that it could never imagine (Im guessing the sub In my studio setup will get down to the high 30hz range or low 40s at -3 db).
3. Tried it on the Cerwin Vega house stereo (Old school AT 15s) and it hit REALLY hard on the notes that it would play but I did not even hear some of the lower notes.
4. Gloves off: Took it to the car and played it through the JL Audio 12W6 (in a 1.5 cu" sealed box) on a Soundstream Reference 700 and it was sonic bliss. You still can not "hear" all of the notes but they are felt for sure.
This leads me to this question: What is the lowest response capable, commercially made system these days. And with that being said, what would it take to hit 35hz at -3 DB at 50' for a 4,000 person audience? Practical...NO. Cool...Hell Yes
PS:
BassPig I did not realize you were on here. I have seen some of your videos on the web. That is the extreme example of overkill and I love it. However, have you ever considered using some very high XMax drivers in big sealed boxes? It seems this setup would produce the lowest possible notes and still be the most accurate sonic wise VS. hard hitting ported boxes. I know sealed boxes do not work in pro audio world but if you can put them in an environment that they can build pressure, its a different world.
