Just looked at the back of the AV 7000 and yes, it has the powered center speaker connections (45 w/ side) for 1 center.

 Though, it also has what is labled as L and R subwoofer outs (obviously low level and controlled by the volume).

Question is, does anyone know if the subwoofer outs are filtered to low frequencies or are they just volume controlled low level outs (with full frequency)??

 Thanks.

They are non filtered outputs. The user manual is on site.

Thanks Peter,

 I'm wondering if i could split these, run 2 subs off these and also run another amp off these to power a center speaker with more watts. I just don't think that the 45 watts that the AV7000 has will keep up with what i'm planning????

The center channel is really just for speech. 45W is usually fine. You will rarely use more than 1W! You will not be getting the centre speaker output via this channel.
