Oh god please help.

I have one disgruntled wife looking at me with angry eyes on valentines day. She's a bass head and I promised the new subwoofer would give us louder and better bass.


I purchased a new svs pb2000 (tried for 2 but they were down to 1) It was replacing a klipsch sw112 that people posted was my weak link.


I put the svs in the exact location of the klipsch, settings on the back of the svs were volume 12:00, phase 0*, LPF set to off LFE. I have the receiver set at 120 hz xover as per SVS, speakers set to small, and 0db on the level with no dynamic bass or anything like that. The klipsch was set at exactly the same specs but the level was minus 3 db.


The SVS cone is moving like it should be loud but the bass is non existent, my towers in pure direct put out more than what the sub is doing right now.



Please tell me I have overlooked something simple, Or is it possible that I expected too much? Movies you can't even tell it's on even though its moving. I plan to phone svs in the morning but I thought someone might be able to point something dumb out so my wife will talk to me again

I got the Half cocked head with a "our old one was over twice as good why'd we have to buy that" and left the room. (she's not actually mad or evil. Just disappointed after I built it up)
The LPF on the sub should be all the way over.


All speakers should be set to small.


All speaker crossovers should be set to 80Hz.


---up dating as I post---


Subwoofer cable should be plugged into the LFE port.


Phase set to zero.


With these settings in place, with the subwoofer level set to +/-0dB, play AVR subwoofer channel pink noise through the subwoofer and turn the subwoofer gain up until you have a sound meter reading of 75dB at the (MLP) main listening position.


---the above are the basic settings---

Being a married man, I'd stick with that.

In the AVR menu, the LFE channel should be set to LFE - 120Hz or if you will, on.

Thats exactly how everything is set minus the gain as I don't have an SPL meter. I just can't fathom why the svs would need to be +3 db on the level and more gain than the klipsh when it has less power and suppose to be not as good. It's not even close right now. Didn't really want to take the gain past 12:00 till after it's broke in nor did I expect to have to. Could be wrong though.

Because you have smoother bass. We have a full set of Klipsch speakers and just recently upgraded to Rythmik and they rock over the Klipsch subs that we upgraded from.


Tomorrow, stop by a Radio Shack and pickup a digital sound meter so you can properly set the gain.


Aside from your wife, properly setup, the PB2000 should rock your world. All reports are it's an excellent choice by those who post on this forum. Check in the SVS thread if you're unsuccessful. It's a fast moving thread so you should quickly get a lot of experienced responses.


Don't max out the sub tonight and enjoy. At normal listening levels, you're not going hurt this subwoofer.

Thanks for the post

I just a/b them with all setting equal just moving the cable back and forth and the klipsch is killing it. I have a friend with a slp meter I'll try to borrow it. Turned it all back down gonna finish my rum and try again tomorrow.

If you are going off how the subs' volume controls are set, this is a factor that means nothing. You could just change the kind of potentiometer the dial is attached to and change power when set at half by five times. It just doesn't matter how you need to set up the gain to get the right levels. Don't worry about it. It means nothing about the sub's overall power.
Well from what I can tell up untill 20-25 hertz their about the same max output then the pb2000 takes over but the 112 has a peak of 116db at 30 herts and your hearing that peak

There is no reason to assume that putting the gain at 12 on both subs should be equal or better output.  Most PB2000 owners, including myself, find that you have to put the gain up to 2:00 or so to get the same output as the old model.  Without using an SPL or your AVR's speaker setup software, it is a wild shot in the dark to assume that two different brand subs should have gain knobs that work exactly the same way.

The 0db and minus 3db I was referring too was on the avr. But after your post and the other fellow I think I was wrong in my head how gain worked.

Yeah, another way to look at it is your old sub might have been at 70% max output with the gain at 12, the new sub might be at 30% with the gain at 12.
So if I can get ahold of a db meter I set the avr to 0db play the pink noise and adjust the gain till it hits 75db. Where do I place the mic in the listening position or by the sub? After that if I want to run it "hot" I adjust the db level on the avr? This was easier when I just plug and played my klipsch and was happy. Apparently I have some reading to do.
Just set the sub amp gain to 2:00, rerun audyssey, then manually adjust the sub trim in the avr back to 0. Try this before you buy a spl meter and report back.
Oh I didnt notice you haven't calibrated your system yet did you use.the mic and auto setup ? Does your receiver have a auto calibration system?
@ jphorst, first thing is to check that your sub is working as it should and that the levels are ok.


I assume your new sub is connected to the Marantz SR5004 AVR in your sig. If so, then as a first step you can check the sub's level by ear using the test tone in your AVR. Can you hear the sub playing the test tone? Is it as loud as your SW112 (play with the vol on your PB2000 just to listen for the level)?


You can do this step even without an SPL meter just to get an idea if your sub is functioning as it should.
crisis averted. Came down to complete lack of research and ignorance of how a sub works. Set the volume to 2:00 or 3:00 ish and it never got louder than the klipsch but I gained bass "feel" in the couch and body over the klipsch. What I really gained was sound quality after I got the volume sorted out I put in some of my reference discs I used for testing all my systems and it sounded so much better sq wise compared to the klipsh as I a/b them. I was falling in love with the music all over again. I can't wait to get this all set up in my dedicated room. I can't believe that little move in volume changed it from barely audible to smiles.


I feel embarrassed about not understanding the gain knob thing but appreciate the help and you saved me an embarrassing call to SVS.


Happy wife, Happy life. She's excited for more stock to come in for a second.

Glad you sorted it out! Have fun with your PB2000.

Congratulations on your success. By the way, when that second subwoofer is up and running, you'll find out what it's life to have your room come alive with bass notes. It's like going from mono to 5.1. Quite the experience.


Again, congratulations.

Glad to see you got the issue resolved!


Your gonna love dual PB2000s. We ran ours a little hot last night during Enders Game and found some new rattles in the house
