Outside of New Age, several classical pieces - no specific references - bass cello or tympani just do not sound right.
EDIT correction: Adiemus In Cælum Fero at 1:58 (it's 1:34 in the radio edit version)
While instruments can have harmonics and overtones, the tipani has a fundamental frequency of around 65Hz, while a double bass cello "E" is around 41Hz. You mentioned a null at your seating position of about 50 Hz, which could explain at least part of your problem, since it's smack dab in the middle of those two frequencies.
A very slight adjustment of the subwoofer can accentuate or de-emphasize certain frequencies, and move peaks and nulls around in a room. As has been stated repeatedly in this and other threads, subwoofer location is critical, so I would not blame the F12 just yet. What should have been done in a perfect world is a frequency sweep with something such as the REW program, to map your peaks and nulls in your room
. Then a more scientific and reasonable explanation could be had.
BTW, I just played In Cælum Fero
, and at 1:58 the bass slam is there in my room
, with the F12. Cantus Iteratus
has an almost constant bass line "march" that also comes through nicely. On another note (no pun intended), my listening position is slightly nulled at around 75Hz, and I have not been able to eliminate it as of yet, so I am missing out on other material, I'm sure.
Room acoustics, subwoofer placement, and equalization are key for low frequency response.
Also, all things considered a sealed sub should be better for music, and a ported sub for HT. While some expensive subs can manage both somewhat well, there are always compromises.
And to remind our readers, the F12 is a ported
sub and an inexpensive
one, after all.
YMMV, IMHO, and all that.
EDIT: You can also have phase cancelation or interference when using "double bass" or setting the front speakers to "large", as well as holes in the frequency response when using less than adequate speakers, such as mini-sized lifestyle speakers.
