What I question: A rectangular mid-range horn... Why?

In consistency with Occam's razor principle I think that they went for rectangular mid-range horn become they layout of the speaker called upon it. I did intended to mention it in my write up but forgot. With spherical horn it will be a different speaker as they would not have height for two tweeters and the midbass that they use.  Living Voice did try to address the subject in their 6 moon article – they suggest that it was deliberate move as they like exponential sound better. I can’t concur with it. I feel that the drivers like S2 need to be used it fast opening horns of Tratrix or La-horn profiles.  I fund that Living Voice explanation of control patters are not reasonable. The people who lay out $300K for speaker would have menace to deal with room acoustics not to mention that controlled pattern of a rectangular horn is a bit faulty believe as a rectangular horn read the wall behind itself as much and any other horn.

  At what frequency range does the transition from the AK151 to the S2 take place? An S2 can be very successfully run down to 400Hz, but not with such a small horn. Instead, they're likely running the S2 as low as possible, limited by the horn, and running the AK151 up quite high. The AK151 is sitting in an enclosure that relies on a zig-zag path for EQ, which might work for mid-bass, but this combination is likely also being asked to produce quite a lot of mid-range; remember, the AK151 is a 15" driver.

I thought about is as well. I do not think that they use the S2 drivers that I know. The new production might not have the 1.25K resonance and the might run it all the way to 500Hz  with second order if this horn is Vitavox 330Hz horn (it look like it is). It is hard to say what in Vox Olympain handles 300-400Hz region. If Living Voice publishes the crossover date then it will be know, without the data it is hard to guess.  Since they went to the efforts to intentionally hide crossover then I presume it is high order crossover with electrical correction of S2 resonances, but it is just a speculation….

  In any case, I'm very pleased to see this project come to fruition, and until I hear otherwise, I'll believe that the Vox Olympain sounds absolutely fantastic. I'd love to hear it.
I do not make any prediction how it might sound but I am generally not as optimistic as you are. I always exercise the presumption of negative results when I see a new loudspeaker. It makes me a jerk among bloggers but it also preserves me from disappointments after I have a chance to learn about the actual sound.   In case of Living Voice there are too many unknown variables that prevent me from questing. Even the S2 driver that I look like I am familiar with – who knows how Living Voice use it and how the new production sounds? As time goes by let see what happens.  I am sure in a month or two the member “coops” will sign the re-sale contract with them and will flood my site with brainless comments about the Vox Olympain excellence.
