Onkyo 805 - RCA to sub double filtration?

[jingoboy_78]

Hi all,


I am a newbie and have the following set up

Sony 40" XBR4
Polk RM 6880 5.1 satelite speaker system
Onkyo 805
panasonic BD 30

Right now I have connected my sub by the 'polk way'.

I am trying to hook up the sub using Sub pre out(using RCA) from the receiver and get rid of the speaker level connections, and re run the auto cali to set it up with the sub woofer (speakers = SMALL and sub woofer = YES) Will that give a more deeper bass?.And also few more things..

1) My powered sub doesn't have a manual cross over frequency set up on its back.I guess the crossover is in built into the sub by default to some frequency.I guess the crossover frequency for 805 will be handled in the auto cali..So will that cause a double filtration?

2) I am a music person and would like to hear more music.So if I am in the stereo mode how far the sub out from the amp will help me.Do I still find the bass what I expect in music too as same as in the movies( since the movies are in 5.1 I guess it has the LFE in th .1 channel) But for stereo do I still get the bass from the sub out from the receiver?


Please clarify..Again thanks a lot!
