If you turn on Extra Bass the sub will now play bass below the crossover frequency, even though the Large front speakers are also playing it.
If everybody followed the "if you have a sub then your main speakers are small" rule, there would be no need for the Extra bass setting. But some people feel insulted if you tell them to set their tower speakers to small, so they use Extra Bass to make sure their sub is used all the time.
Thanks. That was pretty much my understanding. This is the way I set mine up.
For 5.1.......AVR crossover at 120, SUB crossover 120, fronts set to small, extra bass Off
For 2.0.......AVR crossover at 100, SUB crossover 100, fronts set to large, extra bass On
There are many reasons for this. Mostly due to the way that I have equalized my speakers. My front towers are supposed to go down to 35Hz. Make any sense?
