Good CD for testing bass response

If you are just looking to position speakers for optimum delivery then why not use test tones and an SPL meter? That'll give you all the time you need to move things about.

For music, Radiohead's Amnesiac, Pack'd Like Sardines ought to shake some walls. Harder to find and in the classical realms, try the Adagio d'Albinoni by Gary Karr which will add some wonderful natural tonality to some notes down below the basement. The Radiohead is more prolonged though, while the Albinoni is more organic, if you will.

Look for a group called Josh One-Grey Skies EP. All of the songs are bass heavy. Listen to the 3rd track grey skies.

"Pentangling" by Pentangle is pretty good.

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.
