New set-up does not sound the way it should.

[Glen B]

Yes go down to 40Hz, or 30Hz if available. Experiment.

Learn to love your owners manual. Every receiver is different and nobody here knows the intricate ins and outs of every one.

That being said, find the appropiate menu/setting and set your subwoofer to "No" or "Off". This will route all the signal to your main speakers.

If that doesn't work, as a previous poster stated, set the crossover to as low a number as possible.
