My 120 gallon tank is going in my living room and I would like the filter to be as quiet as possible?

I know this is a tough question, but having owned an FX5 I know how powerful they are, but it was a bit noisy.
What would be the equivalent in terms of filtration to the FX6? Is it the Professional 3?

Any thoughts suggestions?

Or would it make sense to go with two FX4 filters?

Thanks for the info.
