|   quick way to set up a Sub? PLease respond quickly... | satz
Jul 25, 2002 10:32 PM | | Hi all,
I might get the opportunity to try out a subwoofer on my HT system in a couple of hours time...
Could you outline the ways to set the Cutoff frequency or whatever it's called?
Or is it just a matter of plugging it in to the amp and then setting up on the speaker setup menu?
Please advise
I currently have my mains as Large, my centre as Small, and my surrounds as Small.
kinds regards

I suggest you place the sub approximately where you like to sit to listen. Then move about the room with something playing on the system and see if you can find a spot where the bass is strong and clean. Then move the sub there. It will probably sound good back at the old chair. As to levels, while you can use meters etc to set it up, for a quick test, agaian, use your ears. |

Quick and dirty:
1. Put the sub right into one of the front corners of the room near one of your main speakers.
2. Set the crossover frequency knob on the sub all the way up to it's highest value, or if it's equipped with a bypass switch use it to bypass the crossover completely. (Your receiver supplies the crossover for the signal before it goes to the sub output jack.)
3. Set all of your speakers to "small" and if you have an option to pick either "LFE=subwoofer+mains / LFE=sub only", select "sub only".
4. Using the receiver's internal test tones, calibrate all speakers to the same value of 75 dB using your SPL meter. Set the sub to 79 dB. Do all of this from your primary listening position. If you don't have a meter you'll have to try to do this by ear which is difficult. Rat Shack has an analog version for $35 that works well.
That's about it, good luck. |
