Granite Audio Complete System Burn-In and Conditioning Disc 

Burn-in your whole system or just burn-in the bass, midrange, or treble sections separately. This Music Direct Special Edition from Granite Audio is specially recorded with Extreme Level signals. The first 6 tracks give your whole system a needed workout. It's like taking your gear a few laps around the track at full throttle. The rest is separated into three sections so you can workout or burn-in your bass, midrange, and treble sections separately. Did you just get a new tweeter or woofer driver and now only need to burn-in the new part to get it up to speed with the rest of the system? Do you have a fully burned-in system already but think the midrange needs some flexing? Would you rather use white noise for it's broadband (equal signal level at every frequency) benefits? Or pink noise for its equal signal level in each octave? You can do all this and more with the Extreme System Workout CD. Bottom Line: your system will sound better when you're done!
