Should I use my Subwoofer's LFE or Line Input?

A I own a Yamaha A/V receiver and a Polk Audio HTS -10 sub.Can I use the sub's left/right Line In inputs instead of using the LFE input?Is there any benefit to connecting the HTS-10's LFE input to the AVRs subwoofer outputs using a Y-cable?The specific connections you make between your A/V receiver and sub will depend on whether you want to use the built-in crossover in the AVR or the sub.The most common scenario is when the built-in crossover sends a low-pass signal from the main speaker channels to the sub.If you use the speaker setup menu, you can choose the small size option for the main speakers and connect a cable to the LFE input.There is no benefit to using a Y-cable to combine both outputs for connection to your single sub in a dual LFE setup.The less common scenario is to send full-range signals to the left and right Line In inputs.You can use the Low Pass dial to set the upper bass cutoff, which will determine the range of bass frequencies that the subwoofer reproduces.
