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?

Not all phasecorrect speakers...or for that matter...speakers in general...are created equal...true...early designs did suffer...but like early Maggie versions that had little to no bass...these issues have been addressed...at any rate... I am a GMA Europa owner...and these have the widest sweet spot I have encountered...in fact...even in an adjoining room which opens into my main listening area...I am amazed at the level of involvement and separation of instruments...
I would suggest one of the many speakers out there that use direct/ reflecting principles, such as the already mentioned Walsh designs, but including Shahinians and others. Look at the single driver website, as well.
Phasecorrect, I was hoping a GMA owner would chime in and comment on the sweet spot of their speakers. I've got my eye squarely fixed on the C-3's. FYI, Srajan Ebaen of 6Moons is suppose to be doing a review on the C-3's in the near future.

Thanks for your response.
I have the GMA C1.5i & the sweet spot is fairly wide when I am in the "official"/intended sweet-spot. Moving my head 6" left & right has very little effect (an effect for sure but practically not too different from the real sweet-spot). Standing up from my sweet-spot destroys all the fun in a blink of an eye! This is an issue w/ most dynamic driver front-firing speakers. The Ohm Walshes & Shahinians could be diff. in this dept, I have no personal experience.
When friends & family come over to listen I have to sit alongside them in the "un-hot" seat & it's much less fun there than in the hot seat. I get the direct effect of the speaker I'm sitting in front of & the imaging is way off. The soundstage has collapsed by now & all I hear is music. Very little depth. The music still sounds very good but the illusion is long gone. Maybe this is my room's limitations OR maybe this is the nature of a 1st order XO speaker?
Anyway, despite this, I ain't changing my speakers anytime soon!
Howdy bombaywalla... your post does confirm the only hesitancy I have regarding 1st or time coherent speakers.

Like I said I'm struggling with what is more important to me. Because my listening/HT room is open to a kitchen area I'm not sure if it's better for the 360 approach of the Walsh design or Gallo Ref. III's or a first order design like those of the C-3's. If only I had access to in home demos.
