I am a newbie to the HT set ups. I have two polk monitor 60s for front speakers and a CS1 for center. I also have a polk psw 505. All these powered by an Onkyo 607.

When I listen to music I don't feel the thump. I can hear it and it's loose and not tight.

I can hear a lot of bass, but when I hear a thump it's not kicking me in chest.

What am I missing?

Music doesn't have as much low frequency bass as home theater movies.

Also make sure your fronts are set to small and crossed over at 80hz. That was the sub handles low frequency info.

did you run audyssey?
do you have dynamic eq enabled?
music curve on?
2 channel or multi channel music?
do you have your speakers set to small and ~80hz crossover set?
do you make any attempt at finding the best place for your sub? google subcrawl for info.

i run monitor 70's and 2 psw 505's and an onkyo 809, and 2 channel bass heavy music can shke me out of the room with the volume high enough. i use audyssey music curve with dynamic eq on and listening mode set to stereo with 80hz crossover.

Thank you.

 

I am getting my life back after 2.5 weeks of 11-12 hour work days. 

 

I have set up the fronts to 80Hz and now its shows up as small in the Onkyo setup screen (Used to have it as Full Range). Now I see a clear difference and the bass more and better :)

I have all other speakers crossed over at 80Hz (including the sub).

 

I have not run Audyssey in couple of year and the room has changed. I will run it again tonight.

The Dynamic EQ as well as music optimizer is off. Should I turn them on?

 

I will try the stereo mode after running the Audyssey setup. 

 

How do I set up the Audyssey music curve in Onkyo 607?

 

Thanks again for your help.

 

My current speaker setup:

Every thing looks good, try putting your sub at 120 instead of 80. That way your sub will pick up everything from 120 and down instead of waiting for it to come down to 80

Spinning the rear tire at 150mph while at 3/4 lean angle will put wrinkles in your seat

To expand a bit on Geoffs post, set the lpf for lfe to 120. This setting is for the .1 channel in a surround mix. The sound mixer has the option to include content up 120 hz in this channel. Setting it to anything lower then 120hz will cause you loose any content between the your setting and 120 Hz. This is a seperate setting from the normal speaker crossover. Setting the speaker crossover to say 80hz will redirect bass frequencies from your speakers to your sub.

OP, the dyneq and music optimizer setting is preference. Try with them on and off to see what you like better.

Ok. Have set the cross over for sub to 120Hz.

Three more subs. Chest thump with music requires about 105dB at the listening position, give or take.

Guess I need to invest in another sub :) 

 

Before I do that wanted to make sure I have the right settings for the one I have.

 

I have set the LPF of LFE to 120 Hz in the receiver.

 

I have also turned the knob on the sub to 180 Hz for Low Pass. I have connected the sub from the receiver by running 2 RCA cables from the receiver's pre-out (Subwoofer) to the Subs Line In (Filtered).

you should run a single cable from the receiver sub out to the LFE input instead of line inputs.

I don't think it should be all the way clockwise, does it have any other numbers marked on each side? Usually the top is 80 and you move it just a nudge to the right. Then try moving the phase switch, it might need a bit more volume too

First time i've seen two LFE inputs, what does filter/unfiltered mean?

Kingcarcas.... What two LFE inputs? I only see one. Download the 505 manual for answers on the connections. http://www.polkaudio.com/downloads/manual/PSW505_ENG_FRMN.pdf


OP--You might download the PS505 manual too so you can see the setup options and why yours wasn't/isn't optimal (like was mentioned, you should connect just one of your sub preouts to the LFE input). Curious, your speaker setup indicates you're running 7 channels; you only mention the front three and the speaker connections that are in the pic aren't being used..... It might be just the way your Onkyo displays but it appears you have surrounds and rear surrounds since there are crossovers set for them. Definitely rerun Audyssey.
