Speaker distance

[greg2350]

Im using a denon 3801 as my pre/processor and seperate rotel amps. I noticed on my denon there are settings for speaker distance right now my mains and center and sub are 9ft from seating position. My question is what change would I hear from setting the distance from 2ft to 20ft would setting the sub to 20ft give me more bass. Thanks for your help.:)

1 more question im using RT600's as my mains and surrounds should I set them to small or large on the denon.

The distance setting is actually a digital delay to ensure that the sound from each speaker arrives at your main listening position simultaneously. So if a speaker is slightly closer, its sound gets delayed slightly so that it arrives when it's supposed to. Take a tape measure and measure from the face of each speaker to the central seating position, then plug those numbers in. This is especially important for cross-channel pans, which are dependant on each speaker being in phase with the one next to it.

Setting the sub to a greater distance would not give you more bass. It would simply put the subwoofer's sound completely out of phase and time with the sound from the other speakers. Measure carefully, plug the numbers in, and you're good to go.

Good info from Kuntasensei.

You may have already found a setting for speaker level or maybe "trim". This is what you want to adjust for more volume if you can't adjust it higher manually on the sub. Have you calibrated your system with a sound meter? Sound level and speaker distance are the two most important parameters (in my book) to nail down during calibration.

Oh, and set your speakers to small. This will push the low frequencies over to the sub where they belong in your setup. Not sure if you have a crossover setting on your Denon but 80Hz is a pretty popular setting. I set mine to 50.
