Help setting up psw111 with denon 1911

gbrower3490

I have the PSW111 set up through the single LFE connection. I also have 2 TSI400's and a CS20 set up as small to output more bass to the sub. The bass on the receiver to LFE+main for more bass. My question is concerning not having enough bass to the sub. There are 2 RCA's on the back of the sub with the right one sharing a single connection for LFE, so thats what im running to the receiver. Im cranking the volume and noticed that there is more bass to the sub after i changed the fronts to small and the receiver to LFE+main, but when i run the sub just to my tv via the RCA's the bass is SO much boomier. What can i do to get my setup to run the bass that the sub creates with just the tv? Just to make sure I'm clear; when you use the single LFE connection to the receiver, this bypasses the subs amp and uses the receiver to power it right? Sorry for the big wall of text, I just received my setup yesterday so I am really anxious to get it working properly and am not too audio savvy. Thanks, Gary

Nope, the sub I believe has it's own amp. Receivers don't amp up the sub channel. If you want the sub to play with the tv, why not hook up a digital cable from the tv to the receivers input labeled as such ? Then just switch inputs when you want the speakers on watching tv.

I think there was some confusion in the way i wrote it. I know the sub has its own amp, but in the manual for the PSW111 it says that this method of hookup "LFE" bypasses the filter in the sub. Im not sure what that means exactly. I don't want to hook up the sub to the tv directly; I was simply mentioning that I did that to explain that when i had it hooked up to the tv, that the bass was simply boomier, which i want. When the sub is hooked through the receiver, it is SEVERELY tuned down. I was wandering if the subs amp was bypassed like the filter is, because that would be a loss of 210 watts to the sub. The sub amp is 300 watts and the receiver is 90 per ch. Wheres my bass?

How do you have it set up in the receiver ? Did you run an auto calibration ? Did you set the fronts to small and the sub crossover at 80 in the receiver ? If so, did you turn the crossover on the back of the sub itself all the way up ? Did you go into the set up menu in the receiver and see at what level it set the sub to ? It maybe set too low, turn it up to around plus 3.0 and adjust from there. Whats the volume set at on the back of the sub ?
Just saying where's your bass with no info isn't going to gather any quick responses. Check out what I mentioned and get back to us. We'll get ya going one way or another.

I tried it the first time running the audessey, it wanted all the speakers to large and the bass to lfe only. This included the sub, but put nothing out to it. I consulted the denon manual and this only verified that the setup of speakers to large and bass to lfe would produce no bass to the sub. I then reset to small and lfe+main and noticed some bass from the sub. I then tried adjusting the crossover at this point. I tried at 80hz at the receiver, as it goes from 80 to 120..(i think). Its at 100 now. The sub itself has the low pass adjuster as well, 60-120. I have tried alot of different combinations with VERY little difference in bass output. It seems like the receiver takes over all the controls on the sub and adjusts it as IT seems fit. When it was running straight to the tv, I could control and tune every aspect of it. It just seems now that maybe the lfe connection to the receiver is not the best way to go? The lfe connection on the back of the sub is also the right side of the rca. There is no dedicated lfe port. Its simply RCA (white left) and RCA/LFE (red right). Would that make a difference? I had the tv hooked up with both rca's and now simply the lfe plugged into the right rca, designated as the lfe. Hope that helps paint a better picture, thanks for your responses

It shouldn't matter which one you use, left or right, connection on the back of the sub. Like I said, go into speaker levels in the receiver menu, I'm betting it's set way too low as some auto calibrations do.

just checked it. bass setting adjusts the lpf for the lfe. goes from 80hz to 250hz. had it said to 80 and had some bass. turned to 250 and had none. from the sub that is.

i think i just found out what you were talking about. I found a tone setting where the db levels were WAY down on the sub. turned it up and now BOOM. thanks for the help. i didnt realize you were talking db levels and not hz freq. much appreciated!

The reason why it was so boomy hooked up to the tv is because #1 when you use LFE the sub's low pass filter is bypassed. The TV's output fed a full spectrum of sound in to the sub. From 20hz to 20,000 hz. Your sub tried to play that. That can damage a sub.

There should be a switch on the back of the sub labled "LFE Yes or No". That should be set to yes. That way the low pass filter in the sub is bypassed and the avr will handle it.

You want the LFE channel set to 120hz in the avr.
