Hi, this is my first post(I'm more of a lurker), so please be easy on me.
I'm running the following:
Panny TC-P54G10 plasma :D
Denon AVR-2805 connected to a Sony DVP-NS775V with optical cable.
Polk
Front pair of RTi4
Center CSi3
Surround pair of RM101
Sub PSW404


I'm not getting really any bass at all. Ive turned the sub all the way up and I get very minimal bass at that level. I have completed the auto setup and I have RTi4 on large, center on small, surround on small, and sub on LFE+Main. Ive got my crossover at 100Hz and my low pass on sub all the way up at 125Hz. What am I doing wrong b/c Ive played music and Band of Brothers(The Breaking Point episode--thought this would be ideal) over and over nonstop trying to tweak everything and nothing as far as bass. My friend brought over his Energy surround system with sub and same result--very minimal to no bass. Please help, I'm starting to lose my patience with this receiver. :mad:

Set all your speakers to small or an 80hrz crossover. You don't want you RTi4 set to larger only small. If you can set it to small and set the cutoff too 80hrz. That should work

On the sub:
Set the cross over dial on the sub all the way up.
Set the phase to 0 (you can try 180 later to see if it improves the bass)
Set the gain (volume) up to 50%

If your AVR has Audyssey then run its calibration (I'm not sure about your model)

Next, on the AVR:
Set the fronts to small w/ cross over of 80 Hz
Set the center to small w/ cross over of 80 Hz
Set the surrounds to small w/ cross over of 80 Hz
Set the LPF of LFE to 120 Hz
Turn OFF the LFE+Main


If not (or even if you ran the calibration) level balance the speakers with a SPL meter. If you don't have one and your AVR doesn't have some kind of calibration/EQ then just try to balance them by ear.

If the bass is too low turn up the level in the AVR during the previous step.

Listen to it with these settings and see if the bass is improved.

if u have the option to set the LFE to "swfr" then do so.... alongwith what already been mentioned

Go into the settings for your DVD player and ensure that the subwoofer is set to "Yes". See Page 32 of your DVD player's manual:

Just to clarify, are you using the LFE connection or speaker input? If LFE is the cable good? have another you can swap just in case?

I just set all this as above and no improvment. I don't have an SPL meter but I let the receiver auto calibrate and still very, very minimum bass. If I didn't touch the sub, I wouldn't even know it was on.

Go into the settings for your DVD player and ensure that the subwoofer is set to "Yes". See Page 32 of your DVD player's manual:

I'm having the Denon decoding, not the DVD player so the 5.1 outputs on DVD aren't being used.

Just to clarify, are you using the LFE connection or speaker input? If LFE is the cable good? have another you can swap just in case?

I'm using the LFE connection on back of Denon. I'm assuming this is correct. I'm beginning to wonder if the cable is good. I figured it was b/c when I pull the cable out slightly,there's a hum, but I don't know. I'm somewhat of a noob to this stuff. http://img196.imageshack.us/img196/1365/dsc00786j.jpg (http://img196.imageshack.us/i/dsc00786j.jpg/)

Should I have the cable going into the singlefiltered LFE in back of sub or do I need a Y-adapter to split cable for both unfiltered LFE?

You have it in the sub pre-out. Move it to the sub out. Should be another connection. Check the manual.

EDIT: I would still try the settings I (and others) suggested earlier. - I see you did try them (once you have it connected to the right place you should be rockin').

If you take a picture of the entire back side I'll try to help you find it.

Move your sub connection to the LFE out, which might be labeled Sub Out (not sure how Denon labels the connects). It's currently in the pre-out, which you would use if you had an external amp.

Turn down the bass a bit if you have it all the way up - this should get you the LFE missing in your current setup.

Beat me to it! - you have to be quick on these boards to not repeat good advice...

according to the picture on crutchfield.com that is the only sub out he has.

According to Page 13 of his AVR's manual, he has it it in the correct output jack:

fuzzyfozzie,

When you ran Audyssey, did you hear the subwoofer playing? Did Audyssey detect it and show that it was a connected speaker?

Craig

I was reading his manual and it looks to be the place to hook it up....hmmm

I would run the Room EQ setup if you haven't already. - Doh! I see you did.

Craig

Yes, the sub did play but no huge, deep bass or anything, but I did hear it send a tone through it twice.
This really has me stumped.

Does he have the LFE turned down in the reciever menu, that's if Denon has speaker parameters?

Bill

Have you checked the settings in your DVD/CD player (as suggested by another poster)?

I would go through all of the audio settings for it to make sure everything is setup ok.

Also, is there anything else to connect to it? Cable TV, etc..

This is the whole backside in two pieces: [img=http://img44.imageshack.us/img44/7629/dsc00792p.jpg] (http://img44.imageshack.us/i/dsc00792p.jpg/)[img=http://img19.imageshack.us/img19/9619/dsc00793j.jpg] (http://img19.imageshack.us/i/dsc00793j.jpg/)


This really has me stumped.
If you only heard it twice, Audyssey may not have detected it. Does the speaker config show it as "Yes"?

Craig

Do you have it plugged into the LFE IN (unfiltered) on the sub?

check in dvd player setup that digital out is raw/stream.

In your AVR manual it has a section on page 73 (Checking the input signal). You should try pressing the ON SCREEN button to see what the OSD says about the input signal from the player.

EDIT: Also, there is a LFE setting in your Surround parameters (-10 to 0db). If it is set to -10 and your player isn't giving it a 10 db boost it may be causing low output. Might check to see if it is set to 0db.

make sure the sub menu on the rcvr is set to "" swfr" and not anythingelse.... I have had this problem when I accidently had the sub set to mains aswell... and mains should be set to small

Ill have to wait for my other set of component wires to come in so I can see the on-screen menu. I'll update then, but thank you all for your help. I appreciate it:)

If there's a L and R input on the back of your sub and your only using one, get a Y adapter and use both. You'll add 6 db of gain.

The PSW404 has a single LFE input.

It does have L & R inputs for Line Level inputs, but these would not be connected to the sub pre-out from the avr.

You'll add 6 db of gain.:rolleyes:

We gotta do this again?

Ill have to wait for my other set of component wires to come in so I can see the on-screen menu.Yeah, the OSD might be useful.

How about this...
I have a Denon 805...
What is the EQ/audio settings on? I noticed on certain field types the bass is very low or not used at all. If you have an audio option to all channels set it to that.

:rolleyes:

We gotta do this again?

I know as I answered this same question on the HSU site;

"The subwoofer output is not 3 db higher, the LFE signal into the sub is increased by 3 db so it wakes the sub up quicker."


Bill

Move your sub connection to the LFE out, which might be labeled Sub Out (not sure how Denon labels the connects). It's currently in the pre-out, which you would use if you had an external amp.

Turn down the bass a bit if you have it all the way up - this should get you the LFE missing in your current setup.

Hmmm, I think he DOES have an external amp…;)

"The subwoofer output is not 3 db higher, the LFE signal into the sub is increased by 3 db so it wakes the sub up quicker."Everything else left the same, using both inputs instead of one WILL increase a subwoofer's output by +3-6dB. But that is not an increase that can't be gained by simply turning up the sub's master volume or increasing the subwoofer channel level trim in the AVR.

Using both inputs can, in some circumstances, help if there is a problem getting the sub to come out of hibernation if an Auto-ON mode is used. But so, too, can increasing the subwoofer channel level trim in the AVR several dB with a corresponding decrease in the sub's master volume.

Bottom line is that a sub is going to be calibrated to the same exact level whether 2 inputs are used or not. If someone needs the +3-6dB increase that using both inputs provides, then they should consider buying another sub or two (or three or four). Using both inputs will not increase a sub's headroom. I doubt, though, that anyone could successfully operate a sub with its master volume set to its maximum.

Hmmm, I think he DOES have an external amp…;)

OK - an external amp connected to a passive subwoofer. Better now?;)

I assumed given the ongoing discussion, that getting into the passive/active subwoofer concept was going to add confusion, but then again, I also assumed that his receiver had a separate LFE out....

This may be a stupid question, but are you not getting much bass anywhere in the room. Or is it just from the listening position (couch)? If it is just from the listening position where is the couch located? If it is in the middle of the room you might just have trouble because of the rooms bass null at that position.

Everything else left the same, using both inputs instead of one WILL increase a subwoofer's output by +3-6dB.

It depends on how the two inputs were created. If a splitter was used at the amp/processor for the LFE channel to get his two inputs, he cut the output by 3db from the processor but he gets it back by using both inputs on the sub. Net gain = ZERO!!
