No one can tell you via a picture if your phase is set correctly. Are you using the LFE input on the sub (assuming it has one)?

huh? the only cable from the sub is going to the AVR, isnt phase supposed to be all the way down, Frequency all the way Up and Volume at 11am position?

The cable actually is running sound from the avr to the sub, that's why it's a pre-out on the avr, and an input on the sub. There are different types of inputs on sub, one uses the sub's crossover, the other is a specific LFE channel that should bypass it (although with some subs you should turn crossover on the sub up to the highest level so as not to interfere with your avr's settings if it doesn't bypass the subs crossover). Phase is supposed to match your system, that's why it's adjustable and your avr may be able to set it at 0 or 180 but sometimes you might want to tweak it (use your ears for best sound). Gain setting on the sub isn't always 11 o'clock as they are not all setup to mimic a clock in terms of the settings of the gain dial; I'd say 25% to 50% of the range of the gain dial is a good start.

You want to crossover the sub at the same frequency that you cross over your other speakers. For example if your front speakers are crossed over at 80 hz than you want your subwoofer to be crossed over at 80 hz as well. Your fronts will play all the frequencies above 80 & the sub will take care of everything below 80

If you're talking about the LPF of the LFE you generally set that at 120 as LFE channel has valid content up to that point. Otherwise depends on your AVR's bass management, though, my Onkyo's Audyssey XT will set the sub crossover during setup.

When you set the crossover point*, you are by definition setting the point at which the lower frequencies from all speaker channels are sent to your AVR's subwoofer output. The LFE channel, which is also sent to your AVR's subwoofer output, is either defaulted to or should be maxed out at 120Hz.

(*Most AVRs, except perhaps for entry-level and older units, allow you to set a crossover point per channel or per pairs of channels.)
