Subwoofer Settings & Rear Speakers

[jla956]

Thanks for everyone's feedback to my previous post. Based upon the recommendations that I received, it sounds like my 10 year old Klipsch SW-8 is just not capable of reaching very far down like a newer sub would be able to.

I'm going to look into SVS, Klipsch, and perhaps some other brands that you all have mentioned. After reading a lot of the posts on here, it seems like there are a lot of SVS fans. By living in the Dallas / Ft. Worth area, I will be able to test just about any type sub I need to - it's too bad that I won't be able to do the same with SVS.

Until I get a new sub I need to know how to properly set up my SW-8 subwoofer. I just bought new speakers and an Amp, so I want to make sure that my sub is set correctly to match them. I need to know how to properly set the "Low Pass Setting". My system is:

Denon 3803 Amp

Klipsch RB-5 Fronts

Klipsch RC-25 Center

Klipsch RS-3 Surrounds

Someone told me that I don't even need to set the Low Pass setting on the SW-8, that the Denon does it automatically.

Also, would it be much of a benifit to add either one or two rear speakers to my setup to complement the side surrounds? I know that my Denon amp has the capabilities to do so, but would it make much of a difference, and is there that much material out there that would utilize the extra speaker(s)? We currently use our system about 60% for HT and 40% for music. My wife is the music user and she listens to mostly SACDs and DVD audios - lots of jazz.

Please let me know your recommendations and thanks again for your help.
