I would try to find different recordings for bass response one instrument at a time. Here are a few I use:
For a very deep electrical bass line I use:
Tin Pan Alley, on the Stevie Ray Vaughan album Couldn't Stand the Weather
For acoustic bass, try:
Many tracks on "Rite of Strings" by Stanley Clarke, Al Di Meola and Jean-Luc Ponty
To assess a drumkit I listen to:
Quaudiophiliac, Frank Zappa - Chunga Basement. Note that this is a quadrophonic DVD-A.
By the way, the recording with the most over the top amount of bass in the mix I recently discovered is the 2 channel 196/24 BR disc of Neil Young's LaNoise. Too much of it for my taste.
To asses bass from your subs instread of mains on 5.1 BLlu Ray, Michel Jackson's "This is it" has incredibly amounts yet well mixed and controlled bass.
