After using the Delos test CD and sound level meter to make crossover adjustments and determine the best position for the MX-200's, I used a variety of movie soundtracks and music for tweaking everything to arrive at the above solution. This record, alas long out of print, has some mighty fine pluckin' of guitar, mando-cello, mandola, violin, bass, banjo and dobro. On side 1, tr.2 I listen for a clean but not boomy string bass sound. This CD is very demanding not only of speakers but of low frequency drivers. The MX-200's in my setup handled these drums easily.
Synthesizers can create lower notes than any natural instrument.
When everything was finally tweaked in my system this played solidly and without booming. A good subwoofer, properly set up, should allow you to distinguish pistols from rifles. Further, on when Clarice first encounters Hannibal, there is a subtle low frequency sound which appears. It should gently shake the foundation but not cause paintings to fall off the wall. For cannon shots there is a sustained series starting at side 1, chapter 9,during the siege of Fort William Henry.
