Speaker punishing bass

Hers's a few to try:
1) MC 900 Ft. Jesus, One Step Ahead of the Spider, tracks 2 and 3,
2) Erich Kunzel, Best of on Telarc, track 20, Jurassic Lunch,
3) Blue Man Group, Audio (on HDCD), any track with the Big Drum, esp. #4,
4) Yello, Pocket Universe, tracks 5 and 10,
5) Don Dorsey, Beethoven or Bust, track 13 and Bachbusters, Toccata and Fugue in D minor, both on Telarc; track 13 on Beethoven or Bust has one of the most vicious hits I've heard.

not mentioned: "Pictures at an exhibition" Dorian DOR-90117
That's one BIG organ. And although not really speaker "punishing" per se, on lyle Lovett's I love everybody, "pengiuns" starts with a really low male vocal and bass that I have rarely heard done well

Stuart Hamm with The urge. Nice 4, 5 and 6-string bassguitar.

Track # 2 from Sarah Mc Laughlan's "Surfacing". It is strictly very deep bass. If this CD doesn't rattle your floors and windows, your system is not producing bass below 40hz.

1. tangerine dream--barryl blue. From the box set compilation. this has 2 twin lead bass guitars, plus their synthesizers at this frequency operating close by.
2. german pressing of spotlight kid by captain beefheart. "i'm gonna booglarize you" . You'll see how good your speakers do w/ this cranked up.
3. 12" import single "radioactivity" by kraftwerk. the 2 drummers and the synthesizers are low on this.
4. If you want to pay, those harry partch albums on gate 5 records feature the catharsis he built--it extends 2 octaves below the low c on a cello.
5. 12" single from 82 of "blue monday" by new order is a good one w/ that percussion and bass.
6. the 12" single from england of relax, by frankie goes to hollywood is good--make sure you have the 9 minute version.
7. 12" single from germany; "lucifer" by alan parsons project.
8. "peon" by captain beefheart from the lick my decals off baby album--you always have to get imports on the beefheart stuff.
9. 12" single from germany of van halen--running with the devil.
