Hi,


I just add a new subwoofer Rogers ASW80 to my system but don't know how to configure it.


1) how to set frequency between 50HZ to 150HZ?

2) how to choose scale from 0 or 180?


I am using Denon 3200 AV amp and Bose AM10 speakers system.


Thanks in advance.

Connect the sub via the LFE/Sub out. In the Denon, set all speakers to small with sub = yes. This should automatically set the x-over at 80hz (I believe that's denon's fixed x-over). Then crank the sub's low-pass filter (x-over) to it's max setting to get it out of the way. The Denon will already be filtering the signal. The sub doesn't need to. Now, calibrate the sub and speakers using an SPL meter and by adjusting the channel levels and the sub's volume control. Here's a couple o links to help out.

Hope this helped.

Thanks Steve, but I have another problem with my new subwoofer. Sometimes, when I use it for DVD movie e.g. train moving in Golden eye, some "DEDEDEDE" sound could be heard from the subwoofer. The sound is quite strange and not comfortable.


Is it the problem with my new subwoofer or should it be a setting problem?

I'm not familiar with that sub, but if you're pushing it pretty hard, the clacking might be the driver bottoming out. Try reducing the gain while playing the same scene, and see if it goes away. The 0 - 180 controls the phase. If the sub is near the main speakers, it is probably safe to set it to zero. If you want to check the phase for sure, get a friend to help, and have him slowly move the control from 0 to 180 while you sit in the listening position. Then leave it where it sounds the loudest.
