So Jakeman, your saying if the Denon has my EP500 at 27ft, when actually it is more like 13ft, I should add another 3 ft to the delay and make it 30ft?

I'm intersred in the reply to this also, since I also have my 500's delay set by Denons auto setup.

Still waiting for the espresso to kick in so maybe I'm not hitting all cylinders yet.....but how would one "turn the mains off"?



Unplug them.

I will wait to hear John's take as well, but I am guessing that his suggestion applies to manual settings/measurements. I would think the auto setup is already compensating for these types of delays. The fact that your Dennon is using 27 ft. vs. the 13 ft. would indicate this.

Randy, my interpretation of John's suggestion is the same as Dave's. Since your Denon has already measured and compensated for time delays in the sub amp(leading some to complain that the longer measurement was "wrong"), no further manual correction is necessary.

And once again I’ve been duped by common sense. Why didn't I think of that?? I'm blaming the lack of caffeine when I asked.

All this talk about calibration is giving me a headache just thinking about it……….I think one of you just needs to come up and do it for me. Make sure you bring your video calibration gear too. I’ve got to figure that stupid thing out too.

……….or, I could just plop it all down wherever it fits best, flip the switch and call it good! Ya, I’m liking that technique already. Headache is gone……..

I was trying to diagnose the odd surround effect i was receiving with DPL II and i needed to turn off my main speakers. Just by unplugging them you can get a real idea of the sounds that are sent to the surround speakers and really understand how 'supplementary' they are.
It was a neat effect to hear only the surround output.
We did the same for the subwoofers during the SVS and Axiom comparison. Again very interesting to hear only the bass notes during one's favorite song.

Right you are, chess. It's also interesting to do the reverse, i.e. use DPLII but disconnect all speakers but the mains to hear the effect of extracting varying amounts of the ambience and/or center material from them.

Just checking back into this thread but I see Dave and John already answered. Randy's Denon has already done the delay measurement so no need to add the 3 ft for the DSP. In my setup I add yet another 3 ft account for the processing of an SMS equalizer. My EP600s are 3,9metres from the main seat but I have them set at 6.0metres in the delay. It seems tighter to my ear there. Notwithstanding the Denon's room correction setting, I would suggest adjusting the delay manually up or down and listen if it tightens the bass further because it may help the overall phase with the mains.

John, if I'm not mistaking aren't you running a couple of EP600s placed mid-sidewall of your room?

I was home for the most of today and a played around with my single 600 quite a lot and I must say that the just aft of mid-sidewall placement in our 25'x14' room sounded extremely good ... I used the Rives test tone CD prior to moving the 600 but didn't manually graph or use the CD after moving it to the sidewall location. Prior to movement I did place the heavy beast in the listening position and walked/crawled around the room with the mains turned off, man I moved that 600 around so much today I thought I'd have a hernia but probably nothing more than due to time it ended up back in the right front corner. After a couple of more tries and tweaking I do believe the sub *may* end up mid-sidewall even though that isn't the ideal location for aesthetics ... but I have been informed that this is *my* room.
