How does the Emerald On Wall work as a center ... ?

Before we came out with the Protege, and Essence, the Emerald was our best center. It may well be all the center you need. It is an excellent sounding center with very clear dialog.  The Emerald has an extremely close tonal match to the other speakers in our line. What the Emerald gives up to Protege and  Essence is dynamic capability. The biggest difference is in the lower range. The dual  woofers of the Protege and Essence can obviously outplay the single 5 1/4" of the Emerald. 

I'll try to sum it up the way I hear it. The Protege and Essence are definitely fuller sounding than the Emerald, this you'll hear at any volume level. It is not a huge difference, but it is there. The Emerald does a very respectable job.

Does Emerald On Wall use 1st order crossover? Phase coherent ... ?

No, the Emerald is not a minimum phase design. In a minimum phase design, speaker height and listening height are critical. This is true of all of this type of design like the older Sapphires, Vandersteen, Thiel, etc.

The Emerald is designed to allow successful placement above or below an optimum listening axis, (for example, under or on top of a T.V. screen). The crossover design of the Emerald is optimized to focus the primary radiation pattern approx 15 degrees up or down depending on if the woofer or the tweeter is on top. If the Emerald is placed at or below approx. 25", the woofer should be on top. If the Emerald is placed higher than this, the woofer should be on the bottom.

"Dynaudio Audience 42- The Emeralds are more forgiving, less fatiguing, better imaging, better bass detail, more neutral overall. 
"I bought the Emeralds partly on the basis of looks. Wanted a very attractive pair of speakers for my bedroom system. First choice was the Sonus Faber Concerto Home. I figured if the Emerald at 1/3 the price could do a passable job, that's what I wanted. Well, they've gone way beyond that! They do so much more than what I expected. First off, they are beautiful to behold. High-end look and feel at mass-market price. Then, the sound> Open, clean, always musical and emotionally involving. After a couple of months I found myself spending more time listening to this little bedroom system. I've been so impressed that I will probably order a pair of the new Jaguar LE with sub modules for my main system. Neither the Thiels or the Maggies I use in that system have completely satisfied me. If ACI can do this at under $700, what can they do for some real money?
"Some of my friends have liked them better than the $3000 ProAcs I played them against If I had to compare these to the sound of something else out there, it would have to be the M&K S-85 mini-monitors, which have a similar driver compliment and size. The M&K is quite a remarkable speaker in its own right, but way over-priced. NHT Super Zeros sound thin next to the Emerald, I would imagine the Super One would be a little more similar due to the larger woofer. But the quality of the drivers and crossover in the Emerald make this little speaker a far better investment than the NHT's, in my opinion.
