This recording has no compression, a huge real dynamic range and extended low frequency content.
It will use up all the system headroom without sounding loud.
Try with headphones first.
Download the fireworks recording at the bottom of this page and burn to CD
DO NOT convert it to an mp3, it will kill the sound of it;

Erika Badu's first album: Baduism has some serious bass and with enough power could easily push woofers beyond their safe excursion. My windows and ceiling vents rattle like crazy whenever I turn her up. Cheaper woofers would be doubling and motor-boating and finally spitting surrounds.
Thanks Tomservo:I downloaded those files and burned a CD and played it on my Walsh 5's driven by Sumo Andromeda II power amps: holy smokes - major infrasonic energy like I've heard only once or twice before. On the Fireworks recordings my PC monitor and items were rattling on my desk like an earthquake. On some of the explosions, the low pressure wave run across my listening room floor and hit me square in the chest! This is definitely a dynamic CD that can fry an amp or a loudspeaker - be careful. I ran my preamp dial at about 11 o'clock, which is the setting where most classical CDs play a concert hall level loudness.
A great CD with extremely dynamic explosions, without any compression, comparable to these wave files, is the Mercury Living Presence CD of Tchaikovsky 1812 Overture and Beethoven's Wellington Victory: replete with canon blasts and sundry gun, rifle and musket discharges - it will blow you out of the room! Oh, and these are great musical performances with verve and stentorian climaxes.

Can't wait until I can burn a CD and see just how low my dipole subs go without bottoming (or popping output tubes on my ARC!).
