Question about Passive Bose Subwoofer, Please Help

480 Views 7 Replies 6 Participants Last post by  kirknelson,

Hello all I am trying to setup a 5.1 channel system in my room and hook it up to my computer.

Components

Receiver: Harman Kardon AVR 310
Speakers: Bose Acoustimass 10 Series II Home Theater Speaker System (All speakers connect to the subwoofer and then the subwoofer connects to the receiver I think this is called a Passive Subwoofer)
Sound Card: Audigy 2 ZS Gamer Edition (Set to 5.1 analog)
Cables: I am using 3 1/8 inch (3.5 mm) to 2 rca from my soundcard to the back of my receiver where it says 6 channel analog input

Problem: When I run the speaker test from my Audigy 2 I get all the channels correctly minus my center. When my center speaker is supposed to sound the subwoofer sounds instead saying what the center is supposed to say. When it’s my subwoofers turn to sound it sounds fine.

Things I have tried: I tried to switch out the speaker with a known working speaker. I tried looking at the cables to verify everything is working fine. I tried flipping the 2 rca cables in the 6 channel direct input in the receiver. I tried banging head against keyboard. I tried the RECEIVER's sound test and the center worked fine.


Possible Reason: I think this is because I have a passive subwoofer and I think there is no fixing this problem unless...


Solution: Is it possible to just hook up all the Bose speakers directly to my Receiver and just buy a new subwoofer? Or will this damage my speakers and or receiver?


I tried to be as thorough as possible if you have any questions or are confused about anything just ask please.


Thanks in Advance

Eddie

Don't plug your RCA's into the 6ch in. As that will only send signal to your left and right. Plug your RCA's into a normal input (i.e. CD, AUX, Tape, etc). Any input would work except for phono. Phono is a boosted input and would blow your speakers immediately.

To me it sounds like your sound card is acting screwy, especially since you said it works with the recievers test tones. Do you have a stand alone DVD player you can try, what about using your Cable feed?


also, DO NOT connect the cubes directly to the receiver, you will blow them in short order .... though many would say that would be a good thing

I refrained, but since you opened that can of worms... :)

On my soundcard the center/sub channels share the same 1/8" jack. Is yours the same way? If so, try swapping the center and sub rca's going into the receiver. My manual was mis-labeled as to which rca plug (white or red rca) was the center and which was the sub signal. When I swapped them everything was fine. This may be your problem.


Edit: Re-reading I see you say you may have already tried this.

Im sorry for saying the B word guys i know they are not all they are cracked up to be.. honestly i feel like throwing them out the window after all the work i did setting up my room the way i want it crawling through the attic etc... all to not have my speakers work..


As of right now i just want it to work.. and yes the sound card does have 3 slots which are center/sub and right front/left front and surroung right/ surround left.


I am really sad that i cant plug the speakers in directly i dont even care about the sub anymore... is there anything i can do.. any options other than just buying the

athena TECHNOLOGIES Micra 6...i dont feel like spending that much money..

Thanks in Advance

It sounds like it is probably an issue with the settings on your computer. Verify your settings are set to the appropriate number of speakers, the volume sliders for the individual channels are all up, check the cross-over settings, etc.
