Having designed and built my own Quarter Pie bass horn, as a Klipsch MWMs derivative, I thought I would share my top 3 tests for bass definition after re-tuning my system.
1) From the best selling jazz recording of all time "Kind of Blue" by Miles Davis, cut #5, "Sketches of Spain": The very beginning has notes from a plucked acoustic bass. You SHOULD clearly hear that the third note is done as a 2-3 string CHORD and not a single string like the first note. This repeats on the 5th note from the bass also. The clearer you hear each string in the chord being plucked, the better. If you then listen to the alternate take of this song on the bonus track #6, the chord is gone and he's using a single note in the same spots with stronger pluck.
2) On the Eagles CD "Hell Freezes Over" on "Hotel California" intro before the vocals and after the guitar: When the bass drum kicks in with 2 beats each time with the congas, the second beat has a distinct pitch shift for each set of two beats on the second beat each time. It will be almost undetectable if you have mushy bass, but clear and distinct otherwise.
3) On "Flight of the Cosmic Hippo" by Bela Fleck and the Flecktones: Victor Wooten's bass should growl at you and where having a sub to get you down to 30 Hz. at least get you to feel the notes as well as clearly hear his fingers sliding over the strings in the midrange. If he's not using a 5-string bass, then he must be lowering his E string on a 4-string bass to get that low.
Khorns, LaScalas, Belles, Choruses, and Cornwalls all roll off above 40 Hz., so this shows the advantages of a good 2.1 setup in the lower registers, especially for 2 and 3.
There are other test tunes, but these are in the top 3 for me. Happy listening and I hope to hear YOUR results here.
