I have a question about my home theather set up that I hope you can answer....
I have just purchased the following components:
Onkyo TX-SR600 AV Receiver
Polk RM6600 Sat/Sub system
Per Polk's documentation, I have hooked the subwoofer up using the speaker level connections from the main front and left speaker outputs on the receiver. I then use the subwoofer speaker level outputs to send the signal on to the Left / Right Front speakers. The center channel, and the two surrounds are hooked up directly to the receiver.
Also, per Polk's documentation, I have made the following settings on my receiver:
Subwoofer: None (since I am NOT using the subwoofer line level output)
Front Speakers: Large
Center Speaker: Small
I have the crossover on the receiver set to 120 Hz.
With this setup, bass from all channels below 120 Hz as well as any content encoded in the LFE channel should be directed the main Front / Left speakers. Since I have the front speakers hooked up through my sub, I use the crossover in the sub for blending the output.
When I play back two channel audio, such as a compact disk -- in Stereo mode -- I get more bass than when I play the same music CD using the Dolby Pro Logic II Music mode. If bass management is working correctly, I should not be losing any bass when I switch from two channel stereo to Dolby PL II, correct? However, it seems like when I spread the music out over all channels using Dolby PL II, not all of the bass that was there in Stereo mode is still getting redirected to the Fronts (and by virtue of my connection) the subs. Obviously, bass management is not an issue in Stereo mode since all of the signal is going to the front speakers through the sub.
Any insight you can offer into why I am losing bass (or at least I perceive I am losing bass) would be greatly appreciated.
