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?

I've heard the Duevels and have found them to have a very relaxed, coherent sound. The omnipolar effect if not a traditional-sounding presentation, but it was one that I got used to very quickly. It was both detailed and relaxed/non-fatiguing, if that makes sense. In general, these are the kind of speakers to which you gravitate after you get tired of all the dog-&-pony/hi-fi sounds out there. These are still on my (very) shortlist as I look for a long-term speaker solution.

One note: I listened to largely acoustic or jazz on these speakers, I didn't try to "rock out," so I can comment on how well they would perform on louder music.

Also, I highly recommend talking to Ted Lindblad, owner of High End Audio. He's an *extremely* nice guy and has a terrific listening space in which to hear the Duevels. Disclaimer: I have no relationship to Ted, but I did buy a Stealth interconnect cable from him, if that counts.
