I've been designing and building home theatres, speakers, subs, etc. for 40 years, and last night something hit me for the first time.
When we set up our HT system, we select a crossover between the sub and the rest of the system.
In the past, I determined the crossover based on the lower SPL curve of my Mains. And at one stage, my crossover was 120Hz.
However I've just realized that if we select a crossover point that is different to the crossover that the mixing engineer assumed when selecting which frequencies go to the sub channel (the .1) and which go to the rest of the system, we could completely miss a section of frequencies.
e.g. If the engineer decides that all frequencies below 100Hz go into the .1 channel, but we select select a crossover of 80Hz on our receiver and/or sub amp, then we will miss the information from 80 to 100Hz.
Note that there is no 80 to 100Hz being fed to the other channels, so those frequencies are effectively lost.
To get over this anomaly, does anyone know if mixing engineers (particularly in movies), adhere to a fixed standard?
If we know that all engineers determine the crossover to be, say 80Hz, then regardless of how good our mains are, we should set the crossover as 80Hz.
I know there is the THX standard, but I don't believe it is used universally in the recording/mixing industry.
Any ideas, comments?
