Kim Womer Posted April 23, 2012 Share Posted April 23, 2012 Can anyone recommend a good starting point to set-up my RT12D sub? I currently have it set for music, room correction is turned on & It sits 12ft directly behind my listening spot, receiver is Yamaha RX V3800, 7.1 suround speaker set-up., room is on the lg size with high ceilng. Where should crossover Frequency be set? volume setting at sub? power setting at receiver? I like a little extra bass punch. Thank you......

mustang guy Posted April 23, 2012 Share Posted April 23, 2012 Welcome to the forum! On the sub, you should disable the HPF by turning it all the way up. The sub gain should be about half way up. In the AVR set the LFE at 120hz. After that run YPAO. Once the system sets up, you can increase the low frequencies by turning up the gain on the sub chanel in the AVR or turning up the dial on the sub itself.

Kim Womer Posted April 24, 2012 Author Share Posted April 24, 2012 Thanks for the help, I certainly appreciate it Not familiar with terms HPF (high pass filter?) or LFE, can you elaborate further? The current sub setting is: Music EQ mode - punch Room correction - on Low pass - 100 HZ Low pass slope - 36 db/octave Phase - 0 Quote Link to comment Share on other sites More sharing options...

derrickdj1 Posted April 24, 2012 Share Posted April 24, 2012 The LFE or .1 channel is a production channel for sound engineers to put the low frequency sounds in. The hpf only let's frequencies above the setting pass to the tweeter and the lpf only let's frequencies blow that setting pass to the woofer. If speaker are set to small the bass limited speakers will have their low frequencies sent to the sub. If some of the speakers are set to large, they will receive the full range of frequencies and the redirected bass along with the LFE. Bass management is done through the avr when all speakers are set to small. To get all the LFE, the sub should have the x-o all the way up or turn it off. The lpf and hpf are not brick walls and have a slop on frequency decay that leaks through. The x-o in the avr should be set 10 db higher than the weakest speakers frequency response.

ivanhurd Posted April 24, 2012 Share Posted April 24, 2012 I don't remember my AVR having the 'small' setting, just crossover points...Is this normal with Onkyo or am I missing a setting in there somewhere? Quote Link to comment Share on other sites More sharing options...
joshjp Posted April 24, 2012 Share Posted April 24, 2012 It should be in the Speaker Setup, you can select large or small. Quote Link to comment Share on other sites More sharing options...

joshjp Posted April 24, 2012 Share Posted April 24, 2012 It should be in ADVANCED SETUP and then you shoud see SPEAKER CONFIGURATION. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 24, 2012 Share Posted April 24, 2012 LFE= Low Frequency Effects - it is the low frequency channel in digital recordings. LPF= Low Pass Filter - It blocks frequencies above that specified from reaching the subwoofer. Sorry for the acronyms. Quote Link to comment Share on other sites More sharing options...

That's how my onkyo is. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 25, 2012 Share Posted April 25, 2012 Here is my message with a bit more elaboration and no acronyms. Welcome to the forum! On the subwoofer itself: Disable the low pass filter by making the "Lowpass" as high as it will go Make the slope as low as it will go Turn the volume about half way up (not sure how high it will go) You can run room correction if you have the mic, but it may be better to wait and run YPAO (see below) In the Yamaha RX V3800: set the LFE at 120hz. Run Yamaha's Calibration ( They call it YPAO). Once the calibration is completed, you can increase the bass punch by turning up the gain on the sub channel in the Yamaha or turning up the volume on the subwoofer itself. I hope this is more clear. Sorry for the nutty confusion! After you do this, let me know if it is better. There are more things you can do, including changing the crossover points of the speakers, repositioning the sub, and even adding a second sub if you really want to shake things up. <- pun intended Quote Link to comment Share on other sites More sharing options...
ivanhurd Posted April 25, 2012 Share Posted April 25, 2012 nope, I meant exactly what I said. and... she's running a Yamaha I gotcha, and I know. I had asked a question about my AVR because I keep seeing people say to pick the 'small' setting and I don't remember ever seeing that option in mine.

My Onkyo TX-SR705's setup menu says: Full Band? yes or no. Bill Quote Link to comment Share on other sites More sharing options...
Kim Womer Posted April 25, 2012 Author Share Posted April 25, 2012 Thanks all for the help!!! Last night I turned the LFE off at the sub, set the LPF at the sub at 125 HZ, set sub power level at AVR to 0.0 db. raised the bass speaker gain to othe 7 speakers by 2 db & it is closer to what sounds good to me. My speakers are set for "large" however, should the setting be at "small"? they are: Front L & R - RF 83 Center - RC 64 Side L & R - RB 61 Rear L & R - RF 83 Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 25, 2012 Share Posted April 25, 2012 (edited) Similarly, the Integra DHC-80.3 speaker setup. In an Onkyo or Integra, if you say full-range on all of your system speakers, then you will get very little signal sent to your subwoofer. The way I look at it, the sub is going to reproduce frequencies below that of the smallest defined speaker in your system. In my all-LaScala system, every speaker is high pass filtered at 55Hz. I have tried many cutoffs, and this one seems to give the most seemless reproduction between my LaScalas and my THT subs.

That will raise the bass up from the sub. Where is the subwoofer placed? Quote Link to comment Share on other sites More sharing options...
Kim Womer Posted April 25, 2012 Author Share Posted April 25, 2012 The sub is 12 ft directly behind me. Also, my sides are RB - 81's not 61's, sorry. Can you explain what the effect of setting speakers to small does in a little more detail? Quote Link to comment Share on other sites More sharing options...
mustang guy Posted April 25, 2012 Share Posted April 25, 2012 One more thing, set the "Bass Crossover" at 60Hz. You should also try setting the mains to small, as this setting will send frequencies below about 60Hz to the sub. This should really kick. The Bass Crossover settings are 40, 60, 80, 90, 100, 110, 120, 160, and 200. You have some big speakers, so I think 60 would be best for you. Lastly, a sub in a corner will be much more effective. It is called corner loading, and uses the corner as an amplifier of a sort. Quote Link to comment Share on other sites More sharing options...
