[QUOTE="Mike Brown, post: 80000, member: 1310"] Re: Got Bass? I am not sure a roller rink (or most systems setup/tuned for most forms of music (live or not live)) is interested in "accurately" reproducing music. :D~:-D~:grin: As an aside, the DBX 120A (or if mixing ITB something similar to Waves LoAir) is also used a ton in rerecording engineer's LFE signal chains for movie mixes.
