Hello Gsmollin,

Thank you very much. I am happy to have joined the forum. It will help me improve my weak knowledge in this area.

Yes, I want to improve the bass.There is a menu where I can change the speaker config,delay, crossover frequency etc.
But what level do I set, what should be the comparative level between speakers or the subwoofer as a ball park which I can tweak a littile bit. You are absolutely right when you say that
"At the crossover between fronts and subs, a phase notch can occur, where the two waves are out of phase and cancel each other. The result is a hole in the frequency response, and coloration of the sound." That is exactly what is happening - causing me not hear the bass.
I do have the manual which is not very informative or helpful for the manual adjsutment. Any pointers might just help. I am totally new to this. I am just trying to learn from you guys and the forum.

Thanks, once again.

Arun
