Swapped long wall to short wall and now I am having some big issues

... by your description it seems that the speakers are already "bright’ in the near field.

No, I didn’t intend to indicate that. I think of the brightness region as being in the area of roughly 4 to 8 kHz or thereabouts. According to my measurements that region is if anything very slightly under-emphasized relative to most of the rest of the spectrum. In the 3 to 4 kHz area, though, there is a narrow peak, although that peak is not quite as high as the one I referred to at about 18 kHz.

BTW, I should add to what I said previously that the measurement microphone was omnidirectional. So the fact that it was positioned directly in front of the tweeters at a close distance (30 and 36 inches for the measurements I did) would not have under-emphasized what it was picking up from the woofers or the midrange drivers, even though those drivers (especially the woofers) were somewhat off axis. Specifically, the mic was an Earthworks M23. And to assure accurate results DEQX supplied a calibration file for the specific serial number of the specific mic,the file having been supplied to them by Earthworks and converted by them to the format that is necessary for use with the DEQX software.

In any event, as Tom indicated Daedalus speakers are known for their accurate tonality and non-fatiguing sonic character. "Natural sounding" would be another way to put it, IMO. They are not excessively bright by any means.

be forewarned

Well - I switched the speakers back to the long wall - but on the same wall as the equipment racks -  so opposite what I had before. not an ideal area adjacent to and behind the speakers with the racks and room cutout on the left. ceiling panels in the opposite orientation. The speakers were set up in the triangular method 9ft offset. I was 1.5 ft off the wall.

The bass immediately returned to an articulate well balanced sound with distinct notes, the midrange was warm and present and the highs not strident.

Back to a pleasing sound - not as resolving as before when optimized with the system on the opposite wall.

One album Alan and I listened to was The Who's Quadrophenia side 4. (Dr JImmy/The Rock/Love Reign O'er Me). This is a first pressing UK Track record which is absolutely vibrant and engaging.  On the short wall the highs were incredibly shrill and strident with the explosive cymbals overriding everything, tonally etched and completely dominating. The midrange was gone. The bass overpowering. Going back to the long wall with no tweaking and the large record cabinet offset on the left side removed (I did put some of the room absorption panels I am using there) - things were close to what I had before.  Very encouraging.

Cds were better but not as well resolved as the vinyl.

thanks skywachr I understand your comments on  arrangement of the speakers but do you put the chair in parallel to the diagonal - then determine the best seating by sliding along that diagonal access? Then drop the other speaker in at that similar distance on the front wall?

Mijostyn - the tweeter drivers are 4" apart - center to center of each tweeter. They also project very slightly towards each other to a central point creating a single wide dispersion high frequency. The response on my long wall setup was pinpoint details, tonality and presence and very distinct separation of instruments.

How many speakers has one seen with an array of tweeters separated by significant distances.  Those tall tower things with 10+ drivers come to mind. Texton arrays with 12 hydra tweeter heads.

the Ulysses are a very natural sounding speaker, They are not bright in the high frequencies.

Mijostyn you mentioned

"You can absolutely correct the frequency response with room control in the vicinity of the listening position and you can be clever with position and acoustic treatments. This is a problem with all dynamic point source speakers in one way or another depending on the speaker's design and the room they are placed in. With basic acoustic treatments an room control (speaker control) you can fix almost anything."

Anything in particularly you suggest?

In response

I do not want to touch any DSP compensation, I've looked into a lot of sound treatments. 1st reflection, ceiling, corner dispersion/absorption. Still proceeding. My long wall setup room treatments do not work in this setup. I have went from Real Traps to GIK which has more frequency and absorption/dispersion related specific products.  I haven't found a speaker position since removing my record cabinet that has had tamed bass. It's in progress. Tape measures, lasers and ears oh my. Jim Smith's Get Better Sound has been helpful for grid speaker placement arrays.   I am considering GIK soffit bass traps (floor to ceiling in the front corners) with range limiters which work predominantly in the 50-250 hz range. Most companies want to treat your room to the point of taking out the ambience.

 I have a friend who was ready to throw his hands up and take down his whole system and worked in minutia for months to finally get it right. He has a short wall setup like what I am trying to accomplish. He will be working with me on the next steps.

I took a number of things out of the room so my guess is that may be a big factor with the atrocious short wall sound.

I encourage your insight.

Thank you

Tom

I have updated my system listing to include the old long wall and new short wall layouts. I also added a pic of the opposite long wall speaker and rack position. This temporary setup sounds much better than the short wall position and is not as optimized as the original long wall location.  Note the less than ideal wall (left corner) and rack positioning around the speakers in this test location.
