But this is a sore subject for people that have to reinforce todays music. Basically it is because people have home theater systems that my system has to 'bump'.
More accurately it is because of the cabin effect(?) of car stereo's, that I am forced to extend system response.

Now I must concur that Heritage music does not have material below even 80 Hz. Todays heavy metal needs punch, but it doesnt need real sub frequency's. Rap/ Hip Hop does not need real sub frequencies either

Today's vinyl based music and protools laptop musicianship, not to mention the boundry setting of jazz and some savvy interpretations of classical rely heavily on real sub frequency.

Engineers from your generation viewed subs as luxury. What with thier extra wieght and bulk, musicians were lucky to get anything below 100Hz let alone real sub frequency's. You could say that accurate reproduction of source material was gimped by ignorance and lazyness.

But rave music changed all of that.

Forever.

So really,
-from my view point-
there should not be a discussion about source material below 35 Hz.
But how to insure that over a 100 db can be reproduced without distortion at FOH mix position.
The key word is distortion. So when the musician hits that low note on his roland 606 at full volume it doesnt stop at your system limiters Or worse yet peak out the amps or even worse yet actually blow the cones. No it doesnt do that, it comes out of the sound system unimpeded, truly "reinforced" and brings the crowd to a peak of extacy.

The sad thing is that system designers think that limiting is a viable solution to fielding a balls-less sound rig.
