After getting multiple PM's about this here is a more detailed response / reason for preferring the SEOS to the Statements:
I have built my fair share of speakers. In the last few years, the Audax line, Statements, Mini Statements, Wedgehorns, Amiga's, Overnight Sensations MT, Overnight Sensations MTM, the SEOS 12's with the DNA360 and Deltalite's.
In comparison the SEOS-12's with the DNA360 / Deltalites are a damn fine speaker all around. They are no slouch in any regard and they aren't even that cheap as diy goes. Looking at driver costs the SEOS with the DNA360 and Deltalite is basically the same as the Statements. A lot of people disregard pro drivers but they sound great! A lot of the cost of the Statements is in the crossover components.
For two channel listening sitting in the ideal position are the Statements better? Yes! However, when it comes to home theatre I prefer the SEOS12 for the following reasons.
Positioning: The Statements need to be at least 2 ft from the front wall. I don't have 4ft of room behind my screen.
Levels: The Statements won't do 115dB without a lot amp and even then you're pushing it. Again, not an issue for music but for movie dynamics it matters. My subs can do 130dB from 12hz to 80hz, the mains need to keep up.
Off-axis response: I'm really enjoying how the horns sound throughout the room. The Statements really had a sweet spot. It was a very sweet spot but I do care about the person sitting to my left and right.
Welcome to the world of pro drivers and waveguides.
