    About to go and collect my new centre speaker, a wharfedale 9cs. I've checked the brochure and it's 89db sensitivity, whereas the 9.1s I have for the rest of the system are 86. Does this mean that on the receiver, I should set the centre to -3db to even it up with the rest, or is it ok on 0db, like all the others?
    I don't want the centre to overpower the rest of my setup. Am I worrying about nothing..I haven't even plugged it in yet..?!

    After calibration with matched speakers I usually purposely increase the centre by +3dB for 5.1 dialogue.

    I would set it up first and see how you go.

    Well, yes, sort of, in theory. The trouble with doing setups based on arithmetic of published figures is that it tends not to be all that good in real life.

    A much better apporach is to buy or borrow a Sound Pressure Level meter and calibrate to the test tones (set each speaker to a 75dB reading).
