Loudspeakers with a wide sweet spot

How can the sweet spot be wide? It's it the best spot, "The Sweet Spot?"

Is this a Zen question?

Here's an old one. Why is a carrott more orange than an orange?

Mirage OMD-28. Reasonable size and sensitivity, fast, bass down into the 20's, very good imaging, turns the whole room into a good listening area. $7500/pair. When Chris Martens reviewed 'em for Absolute Sound, he bought the review pair.

I have their little brother, the OMD-15 and couldn't be happier with a speaker purchase, and they're my tenth or eleventh.

Although I am a big fan of horns and field coils, the speaker with the widest sweet spot that I have seen/heard so far is made by High Emotion Audio. The tweeter is unique and patented. It goes down to 2KHz- well within the range of image definition. It radiates nearly as well to the sides as it does forward. You can easily hear the soundstage image while standing off to one side, not even between the speaker. They are also not critical of setup- the image just grabs hold even if very casually placed.

This is one of the more high-speed, detailed speakers made, while being relaxed- an uncommon combination. The speaker (S7) is easy to drive with tubes or transistors. The retail is about $5,000/pair.

This reminds me of the Energy Pro 22 - they had a hyperdome tweeter that they made themselves and which was crossed over at 1.8 Khz. Great speakers with a lovely natural wide dispersion and very reasonably priced back in their heyday. No doubt Dr. Floyd Toole had some influence on them. Of course, crossing over a tweeter that low has its problems in terms of maximum SPL without distortion and compression and potential to "blow up" but for a bookshelf the Pro 22's were outstanding sound for their modest price.
