Impressions of Coincident Speakers

@bradf 

My woofers face inward in my current setup, yielding a much better in room response (via listening and measurement), than facing outward.  Room is approximately 14.5 feet wide by 21 feet long, suspended wood-frame structure (I still miss my old cement floored room).  I have tried placement on both long and short walls and have oriented the woofers in both directions in both configurations. I wound up on the short wall where the speakers are around 9' apart, and close to 4 feet from the rear wall, with some toe-in.  I would say I listen in 'mid-field'; I don't use the stock spikes - Isoacoustics Gaia I footers made a huge improvement.   Experimentation is certainly necessary to achieve correct  placement with side-firing woofers; perhaps more so than typical front-firing woofers.  Happy listening.  

@bradf Depending on how far the speakers are from the front wall, I sit between 10 and 12.

I think currently Im sitting about 10' with the front of the speakers out 5 feet (approx) front baffle to front wall.  One limiting factor is I really can't move my seating any further aft, due to a division in wood and carpet flooring. The aft legs of the sofa are near the edge of the carpet.

Hi Brad,

I really suspect that 10 to 12' sitting distance will be fine for you. Although the Total Eclipse II are not identical to the Super Victory III, they share 1st order crossover design and Coincident similarities. Israel Blume does insist on certain philosophical and implementation ideas  that I believe apply to all of his speakers. 

I sit 10 ' from my speakers and the vast majority of the time I cannot place the music on the face of the speakers.  In other words the music seems to be everywhere but the speaker location. Now of course this varies depending on the recordings in use.  My point is that the speakers effectively disappear in the listening room with good placement and totally affected only by the. recording limitations. 

Just have this experience last Night. The musicians were either in my room or I was seated in their recording venue (Again it varies on the recording). Bill's suggestion of using a software program is an excellent idea. I did not but I just got lucky with my room😊. Brad thanks for your kind comments above and I wish you the best in this endeavor.

@bradf I think the SVIIIs will be fine out 10-12 ft.  If your listening position is fixed, that certainly makes the speaker placement protocol easier because it reduces the multivariate problem by one element, and a very important one at that.  In my room, the optimal speaker position was a little closer to the front wall, which if it holds true in your case, could get you another foot of breathing room between you and the baffles.  I'm a bit more optimistic about you getting a satisfactory sound with the SVIIIs if you are willing to use REW measurement.
