In the Denon manual there is a section that explains why the actual distance and what the setup distance shows for a sub are so different, it has something to do with the internal circuits in the sub, can't remember the exact statement but it has been discussed on this forum before. Bottom line, I've found the auto setup to work great.

Tarun, as suggested in the manual, my view is that you should trust Audyssey rather than the tape measure for the sub distance setting. More factors than the simple physical distance are involved.
Most(all?)receivers use 75dB as the level of their internal test tones when setting reference level.

I'll echo what some of the others have mentioned. My 2805 setup places my EP500 around 27ft, when in fact it is more like 12ft. The Denon manual states this is normal based on the internal circuitry of many subs. I wish my 2805 had the Audyssey, ohhhhh upgradeitis strikes again.

Ok, I will leave the distance alone after the audessey setup. My queston then is on the ep600, I have the crossover set to bypass and the load at flat (i may be wrong on the load). Is that ok?
Thanks for all the responses.

That is how I have my EP500, and will soon be getting my EP600. A lot depends on your room size. The pamphlet that came with your sub talks about the different settings. I use Bypass for the crossover and then adjust the crossover on my receiver to 80hz. I also use "Flat" as that seems to work best in my larger room.

Both my brothers have room equalization features in their processors and I don't find them very accurate for low frequencies because of the long wavelengths and boundary effects. They do a better job at HF.
My rule of thumb is to measure the distance then add 3ft for every processing step. So for a vented sub located physically 8ft away, I would add 3ft for processing at the receiver and 3ft for processing at the subs DSP chip. If you have an equalizer add yet another 3ft. I have generally found that rule of thumb works well. Occasionally, depending on room acoustics, I will add another 3ft. So for your sub you may want to listen if setting distance from 14-17ft sounds any tighter or louder than at 25ft.

Ok, just an idea I had to test for the correct sub distance. If you sent a frequency that both your fronts and sub could play sufficiently loud at the same time (say crossover frequency), couldn't you just adjust the sub distance until you get the maximum SPL output? Technically this would mean that your sub and mains are perfectly in phase (at the location you're testing at), which is the goal of the whole setup thing. Sure there may be some variation as you drop to lower frequencies due to different response times of the sub and mains, but crossover is the essential one to match, isn't it? I haven't tried this myself yet, but I may when finals are over. Has anyone tried this or know if it'll work (or why not)?

Great suggestion Jason. Its one that I use as well to doublecheck.

Jakeman, not sure you've worked with this newest setup product, but it is different than previous attempts, and has some good reviews out on the net by credible sources. Here is a good article on how it all got started by Tom Holman(father of THX) and Chris Kyriakakis. An end result of 5-6 years... http://www.audioholics.com/techtips/specsformats/AudysseyMultEQ.php

Great point of reference SirQuack. Thank You. I have to wait until the kids and wife are out of the house to do this test...because my room is in the basement and the running around upstairs creates its own BASS effects.
More after I run the setup..... I am thus far happy that I went with this 2807.
