I just brought a set of Wharfedale Diamond 10 and am setting these up with my Sony DA2400es receiver.   I have set up the front speakers as larger and the centre and rears as small as recommend in the Wharfedale instructions. I also have the crossover freq set to 85Hz on the sub (this is the max setting) as recommended in the Sony Receiver instructions. Assuming this all makes sense what crossover frequency should I be setting up on the Receiver for the Centre and Rear speakers. The default setting is 120hz.

the answer lies in above which frequency is the sense of sound directional? about 80-100Hz so don't set more than 100Hz unless absolutely needed (ie speakers can't cope)

but don't set it too low as you are not making use of the power of the sub, so don't set it lower than 80Hz.

haha made it easy then:

look at your manual re frequency range of the centre and rear speakers. it should say something like frequency response 65Hz-20000Hz -6dB.
you should set the crossover at around 20Hz above that, as the frequency response is an academic cut off and in practical sense the speaker is not capable anywhere 10-30Hz within that lowest number claimed.

now this is the science that i buy, and someone else will have their opinion and that's ok.

ALSO
i suggest you set the bass to come out of BOTH sub and large (ie your fronts). but that's how i like my bass, coz the subs you normally buy aren't great at all low frequencies (yes that's true)

The manual states the nominal frequency range for the rears is 55-24khz and 70-24khz for the centre speaker. There is also a crossovers frequency, I.e 1.6khz for the rears and 2.8khz for the centre.  Which one should I be using?

the crossover frequency in the manual refers to the speaker's separation of sound between the drivers (woofer/mid/tweeters) and has nothing to do with setting up the amp.

55Hz and 70Hz are the numbers and use 80Hz for rear and 90 Hz for front. if there is no 90 Hz for front do a test of your best action comic movie between 80Hz and 100Hz - and then I'd probably choose 80Hz.

ie i'd choose 80Hz for both.

and use sub AND large speakers for bass output

also set your LFE dB and/or cutoff to the highest if you come across that option.

joker97's comments are all valid.

I'd just add that to do this nicely you'd want to source some test tones and run through those frequencies to see how it sounds in practise in your location. I sourced mine off the net and burned to a CD format, all for free so hunt around.

If your sub and mains cross frequencies then you'll need to pay particular attention to the sub phase, as they will counteract each other if not set correctly. The test tones are the best/easiest way to check and correct this as the sound is constant, - you are not waiting to hear it in music etc.

Ideally you'll be doing this with a sound level meter but to be honest you can do a lot with your ears alone. You're after a fairly constant 'volume' level as you run up the frequencies and the sound switches from subwoofer to main speakers. Play with the crossover settings in the receiver until you achieve the best result.

Could you not just use the auto setup that comes with the receiver?

The receiver is Sony STR DA2400ES.  The auto calibration does not automatically set up the crossover values.
