you have your main speakers set too low in the frequency range.
on average human hearing only goes down to 20 hz, and not much music really plays that low. so basically you have made your speakers full range bar 20 - 24 hz. what speakers do you have? they have full specifications on the frequency range possible and will give you a better idea of the filters required. generally speaking everyone in here was correct with the 80hz low/high filters. you set them to the exact same number.
Now you also need to realise that the order number of filter actually makes a big big difference! if you select a 80hz high pass filter on your main speakers, it will still play sounds below the cutoff frequency. how much it plays is dependant on the filter order you use.
i have attached a graph here to show you the basic difference

So you can see here that a first order filter will have the most "overflow" into the frequencies you want to cut off while the fourth order filter in the devialet will have the least.
Now the best filter order to use is going to be different for every speaker, enclosure etc but a good place to start is 80 high and low pass with a fourth order filter.
