What is correct crossover 80 or 120?? AVForums
The crossover and LFE are two distinct areas of the system. LFE is encoded in the 2120 hz region, but this same information is also encoded into the normal speaker channels as bass. The LFE is 10db hot, so when you have a sub, the LFE is what you hear, the LFE information in the normal speaker channels isnt heard as the sub is doing the work.
