Dawgbyte, yeah first order systems generally have a small sweet spot where they are in absolute phase. My Europa's are no different. Having said that, at least they HAVE one. Second, fourth order designs don't. I'll take that small sweet spot over NO sweet spot anyday. Besides, even when two rooms removed from the Europa's, they still sound remarkably coherant. I asked Roy from GMA about this and he said since the speakers are time/phase aligned, sound that hits the wall and reflects into the room is more coherent than other order crossovers. There is no perfect speaker, but to these ears, which were recently tested to be better than textbook, 1st order is closer to the musical truth.
Do 1st Order XO's produce a smaller
In my mind I'm trying to come to terms with two possible conflicting desires:
1. The desire for transparency, accuracy, dynamics and a wide halographic soundstage presentation.
2. The desire for a much larger sweet spot to compensate for multiple listening positions. I want the advantage of on-axis detail, but I don't want this space to be limited by inches or a few feet.
The concept of time coherency makes perfect sense to me and seems to be a superior design philosophy in conjunction with the ability to control phase shift (smear). However, based on what I've read it appears most of the 1st order time coherent designs being created today have relatively narrow sweet spots. If you're on-axis these designs can be musical nirvana, but what if you're off-axis or move to another location in the room? Typically you tend to lose the benefit of this design.
Conversely one has the option of going the Ohm "Walsh" or Meridian route and get an incredibly wide/deep soundstage because of the 360 degree sound dispersion. I've heard you can move around within a room and the sound quality does not deteriorate significantly. In other words this type of speaker design fills up an entire room and sounds great where ever you are sitting or standing. However, are we giving up a critical level of accuracy with this design approach? With sound esstentially arriving at our ears at different times are we really getting an accurate representation of each instrument? Is the music being smeared in some way?
I guess like most audiophiles I want my cake and eat it too! I want transparency/accuracy/dynamics as well as a wide and deep soundstage that doesn't depend on a 12" on-axis listening/positioning limitation. Are there any designs that meet these qualifications?
