I am so confused on my first system

Av demon x540bt

Speakers JBL 510

What do I set the crossover at?

Default it's 80Hz been told to set them up at 120hz

It's specs are frequency response is 150hz - 20hz (-6dB)

Anyone?

Those are little speakers. That +/- 6dB spec means actual response to be something like 180hz.

3" sealed box speakers - so will be close to 180hz.

Thank you what do I set sub at 46hz to 250hz

On the subwoofer itself you set it to maxmium.
If your AVR has a setting for the subwoofer crossover you want it to 180hz.

Could not set them at 180hz only 200hz inc the sub will this be Ok?

Skyfall sounds great when the bass kicks in anyway to turn it down a bit playing Xbox one?

Can I hijack please

Sub - Wharfedale SW150 - Frequency Response 35Hz - 100Hz - Crossover Frequency knob on rear is 35Hz - 85Hz
Centre - Q2000Ci - Frequency Response 75Hz - 22kHz
Fronts - Q2020i - Frequency Response (+/- 3 dB): 64Hz - 22kHz
Rears - Q2010i - Frequency Response (+/- 3 dB): 68Hz - 22kHz

My Amp STR-DN1050 also has a Crossover Frequency Setting option.

Does this mean I should set the crossover on the sub to 85Hz, then on the amp set the centre to 80Hz and the fronts and rears to 70Hz?

Set crossover to max on the sub (I think this only affects hi level in puts, ie speaker passthrough) and volume to halfway
As previous posts start off with about 180 as crossover on the avr.
Doesn't the dn1050 have a setup mic etc?

"Set crossover to max on the sub (I think this only affects hi level in puts, ie speaker passthrough)"

Typically the subs owns crossover effects high and low level inputs.

Speaker pass through is a high pass, this is typically fixed. Some higher end subs allow a adjustable high pass but the only one I can think of is the SVS SB/PC Ultra 13 which is close to £1800. Typically other high passes are fixed at 80-120hz.

You only use high pass when you connect your speakers to the sub (high level) then sub to the amplifier. Or you connect your power amp for the speakers to the sub, so your power amp only received >80hz. Again this is only available on higher end subs. Or you could use a Outlaw ICBM-1
