Wondering if other Outlaw 990 users have found that auto setup puts the EP500 significantly more distant than the actual measurement. For those that have, have you been able to determine if the setup or actual distance seems to work better ?

Mark, powered subs have electronic delays which cause the sound to arrive later, as if the sub was farther away than its actual physical distance. Trust your 990, not your tapemeasure.

Enjoy the music, not the equipment.

My brother owns the outlaw 990 and an EP600 and after spending a couple of hours with it we concluded the automatic delay is not accurate. The sub was 10 feet away and the 990 kept giving us readings of 24 ft. I've yet to find an auto delay function in any receiver which accurately sets sub delay. The acoustical physics involved make it a daunting task to set delay properly. Auto- equalization rarely comes out right with bass frequencies. My suggestion is to add 2.5 to 5 ft to the actual distance then fine tune depending on your ear. With my brothers an additional 4ft gave the best result.

------------------------------------------------------- NOTE: • When measurements have been made using the measurement microphone, speakers with a built-in filter such as subwoofers might be set with a value that differs from the physical distance because of the internal electrical delay. -----------------------------------------------
The above, from the Denon manual, explains the difference but does not indicate that the setting should be changed to actual distance.

Hi BB. Yes the internal processing of a DSP or an equalizer results in about 2.5ft of delay not 14 ft like the Outlaw suggested. Delay can be expressed in distance or milliseconds. Most people find it easier to set using distance ie. the further the distance, the earlier the sound starts at the speaker/sub. So a sub with a long distance delay will start reproducing sound well before a main speaker of shorter distance. They will be out of phase if the delay settings aren't right.
I also have a pretty sophisticated equalizer a Behringer DEQ2496 with all the bells and whistles and it recommends in its manual not to use the auto functions below 100hz. It has more to do with the difficulty of accurately measuring LF sounds owing to the long wavelength. Its typical Behringer with no BS.
People say the the latest Audessey technology has finally solved this problem but I'm in wait and see mode on this one. I would only use the 990 auto feature for speaker settings.
