A Zu / Tekton / Omega Speaker Positioning Thread


Friends,

I'm a couple of months into ownership of a pair of 10-inch fullrangers, Zu Omens in this case. In extensive play with positioning, I've managed to get incredible tone out of them, the best I've ever heard -- but great soundstaging still eludes me. Specifically they fail at creating images outside of the speakers. On a recording of Bill Berry's Ellington Allstars, for example, my old 2-way monitors placed a trumpet 2.5 feet to the outside of the right speaker, and a sax just to the left, still outside the speaker. Now it's just two _great-sounding_ horns emerging directly from the right speaker.

We may be up against a reality that the limitation of 10-inch fullrangers is the inability to completely disappear, but let us have a discussion of best practices when positioning these guys.

I'm so happy with my Tekton Lores and 4.5s. The 4.5s especially throw a very wide soundstage in my 14x16 office, I can't believe it myself at times. For example, playing Neil Young's "Down by the River" or "Cowgirls in the Sand" the soundstage is at least 5 feet outside my speakers. Young's rhythm guitarist is 5 feet outside the leff speaker edge and 5-6 feet forward, Neil is solid at center the drummer significantly behind the bassist several feet back right and coming off the right wall about 4 plus feet from speaker edge. The height is about 5 feet eight or ten inches. It is incredible and blows my mind. On his piano pieces you'd swear you were listening to Maggie's. No joke! This happens with either the Primaluna Dialogue 1 or Jolida Fx 10. Of course the Primaluna brings out a stronger bass by a tad.
Tone is right on and very musical with great coherence, detail is very good.
I've got NOS Russian 6N3C-E in place of the stock EL34s, RCA clear top side getter 12AU7s, and Sylvania NOS gold pin 3 mica black plate 12AX7s as driver. Man, I'm really happy certain A'Gon members turned me on to these speakers. My Infinity Prelude Compositions also throw this type stage but with a different sound character, all good.
Also great to hear, Mikirob. For everyone's benefit, how about we share the following distances, measured from the center of the driver:

Distance out from front wall, width between drivers, driver to sidewall, and driver to your ear. Then comment on toe-in.

Right now my drivers of my Omens are 45" out from the front wall, 96" apart, 29" from sidewalls, and 102" from my ears, toed in so that the drivers would intersect just behind my head. The center fills in pretty well, but images that should exist outside the speaker pretty much reside at the driver. Moving the speakers inward from the sidewalls still doesn't get them to project the images outside the speakers when called for.
Ok, I will measure distances. Get back soon, clear up a little work stuff first.
Ah, the 4.5's have a driver that's half the size of Omens or Lores. Makes sense that they might to a far better job with the disappearing act. I'll listen to "Cowgirl" and "Down by the River" tonight for comparison.
I have Lores. Not sure my exact dimensions off the top of my head, but it's something like 35" from front wall to rear of speakers, low-20's inches from side walls to middle of drivers, and toe-in is so that they cross about a foot in FRONT of my face. I have preferred this approach as it gives a wider sweet spot and doesn't really sacrifice on imaging as far as I can tell.

One thing not mentioned yet that I also do - tilt the speakers up a bit. I have the front spikes elevated about 1/2 inch above the back spikes (a 1/2" wood block under the front ones). I haven't experimented with different amounts of elevation, which would probably be a good idea, but the elevating completely transformed the imaging/soundstage from laser-focused and sometimes intense to the point of listener fatigue to much more natural, spacious, and still with good imaging. If the point of toe-in is to listen just slightly off-axis, it probably makes sense to do so in the vertical dimension as well as the horizontal.

Also important to note might be room treatments. I have GIK panels at first reflections on sidewalls, GIK bass triangles floor to ceiling in front corners, and a GIK panel I put in front of my flat screen TV. I also have four GIK 2'X2' diffusion panels - two at front left and front right, and two directly to the rear of listening position.
