A STRICTLY SPL CD I FOUND OVER TRYING 20 OF THEM was spl shootout. it pounds and has repeated bass hits so u can regulate distortion. it also has a bunch of tracks that are listed by hertz. one of the tracks goes from i think 120 htz to 10 hrtz. its kinda expensive,,, like 25 i think, but well worth it. if u wanna fine tune ur highs\mids, itll also do the trick
lil jon.. lots of bass, if you can manage not to vomit due to the poor quality of the music itself lol man I don't know how that guy hit top 40 anything with the crap he releases.. honestly. That aside though, are you just looking for bass music, or are there certain genres you'd like to find for auditioning a system?
