    The settings on the AVR are as follows:




    • Subwoofer: yes

    • Front: full band

    • Center: 80hz (THX)

    • Surround: 80hz (THX)

    • Surround back: No

    • LPF or LFE: 120 Hz

    • Subwoofer mode: D. Bass

    • Subwoofer level: 0 db

    I took the Sub back to circuit sh*tty the other day.. the sub works fine with the LFE input...



    Next step is to sit on the phone with an Onkyo Technician and make sure I have all the settings correct.. .

Well the next step would be to make sure that all the settings are set to subwoofer yes, and set your crossover as well.  The amp usually has a crossover which tells the microprocessor which frequencys to send to the sub.

I have an onkyo tx-8255 receiver and i bought a psw-505 polk audio subwoofer to supplement my Boston acoustics cs-26 bookshelf speakers but i cannot get more than the deepest of bass to emit from the sub. ...


The problem is you are dealing with two different brands of speakers, I know because I ran into the same issues you are facing now, I had a Bose sub matched up with two Radio Shack Satellites and sound was not balanced it was awful. Finally I broke down and bought a pair of Bose Satellites and I have never regretted it since. The point I'am making is that when you mix brands the sound will be unpredictable, the problem with most subs is they have a very low roll off frequency even without the crossover making almost impossible to match speakers.

Where is the hdmi cable on the tx-sr703


Sorry but this receiver has no HDMI inputs or outputs. I believe you have to step up to the TX-SR803 before you get any HDMI capabilities. Good luck.

Powered Or Unpowered Subwoofers For Onkyo TX-8511


Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.

What we wound up doing was ensuring that the LPF setting was the same on the receiver as on the sub... that cleared up our problem

No sound from Sub Pre-out on Onkyo TX-SR606


Also, it could possibly the preout terminal itself that is not working. One way to prove that is by transferring the subwoofer cable from the preout and temporarily transfer it to the tape out section. If it ouputs sound from there, then that means the speaker and the cables are working fine and it's just the preout terminal itself that is not picking up anything. ^_^

Very low ouput from subwoofer preout


The problem was that some subwoofers (inluding my velodyne model) cannot process the LFE signals through the line level inputs on its amps, so the other way to run your subwoofer is to run the front left and right speaker outputs from your receiver to the speaker-level inputs on your sub, and then plug your front and left speakers into the soeaker level outputs on the sub. you have to set the onkyo receiver to "Subwoofer: No". that way the LFE signals are sent through the front speaker channels and you will get the same BASS output as if using the line-level input. O So yes it does require a bit more speaker cable, but it works fine now.

Onkyo 805 sub hook up problem


Talked to tech support at Onkyo and there seems to be two (2) places you can hook your sub up to. I placed mine in the wrong slot. So please double check where you placed the sub connection.
