Why are you trying to get sub 20Hz in your room in order to play Bruckner's symphonies or anyone else's? The orchestral bass goes down to the mid 30s Hz limit nearly an octave above 20Hz. The only exception would be large pipe organ where the lowest note is 16Hz. Bruckner's crescendos are weighty not only because of the massed forces but also the relatively low frequency range of the trumpets he used (in F not C) and the way he orchestrated the brass and strings. The lower range instruments have more overtones in the audible range and therefore fill up the soundfield. The slow tempos also help increase coherent reverberations. Mahler and Richard Strauss use the brass and horns in more varied fashion and are more contrapuntal in the scoring. 

Steverino, I feel that this rational that “orchestral bass goes down to the mid 30s Hz” is completely faulty. Indeed, if you sit with a microphone and measure sound is reasonably large whole then you might not see a lot of frequency response at -3dB in sub 20Hz. Let leave aside the fact that most of the microphones and sound possessing devised do not run or even cannot be calibrated under 20Hz. The question I ask: if you measure 10-15Hz at let say -40dB then what reasoning you have that it has no impact to listening experience? The ULF are very different rans and has own way to impact listening awareness and there is absolutely no reasoning to look for frequency evenness at infra sound. The fact that infra bass has a huge benefit to listening experience is not a subject of argument for me, I am converted long time ago. The question that I ask myself now is what kind infra bass should it be? There are many options available….
