Klipsch Cornwall IVs KC62 and yamaha AS2200 setup questions

Also, The AS2200 as A and B speakers and you can play both A and B speakers in its bi-wire selected mode?  So could i feasibly connect the sub to B speaker and select and b to play or is it just better to run in series from the main speakers?

I have one KC62. Would i have to run wires from both main speakers to the KC62 or just one ? 

On the back of your sub it should indicate "speaker level input". Connect speaker wire there and on the other end, to your main speakers.

So you will end up with one set of speaker wires connected to your amp, ( which is also connected to your main full range speaker) and the other set connected to your subwoofer which is also connected to your main speaker.

It does have speaker terminals.  So use speaker B terminals or use the same one as the loudspeakers?

Try connecting via the speaker connection on the sub ( presuming it has one). Then set the volume on the sub to integrate with your Cornwall's. Should give you good results.

Cheers.....

Thanks for the reply. It may be my room but the bass hasnt been stellar on the cornwalls. Is it clean yes, articulate yes. But it fails to reach deeply on songs like Aquamarine by Santana. I ran the speakers for months prior to buying the sub. 

I put the sub into manual mode and have it set around 1 o'clock. 

When i plugged the sub into Line out from the amp, the amount of bass produced was huge...the volume control on the sub seemed to be far more active. Big issue there is you have to volume match. I have the speakers direct wired to the amp..the sub is connected to Line out or pre-out on the amp not via speaker connection

1-Why cross over at all?  The Cornwalls are known for great bass.  Go full range to the speakers.  Run from the Yamaha direct to the speakers.

2-Try without the sub and see if you are happy.  I would be.

3-Pre-out on the amp should control sub volume.  You may not hear much. Set the sub as low as it will go or see if manual mode will work?

That's the idea of a good sub match.  It will just compliment the bass.  You just might have more speaker than sub.
