I have a pair of James Loudspeaker QX806BE speakers in my kitchen. These are in-wall speakers with a quad 1" Beryllium tweeter array and dual 7.5" woofers. After a ridiculous amount of work, I was able to pull off the more complicated flush installation; standard installation leaves them sticking out 3mm. They are powered by a NAD M33 integrated streaming amp that uses a pair of the excellent Purifi 1ET400A amp modules. However, in this case, the most important feature of the M33 is Dirac Live multi-phase "room" correction. The speakers sound absolutely awful without correction. They reminded me of a PA horn. As you can see by the measurements, the crossover is very poorly executed. The subjective results after using the latest version of Dirac Live (V3.3.3) are, in a word, amazing. They magically transformed from midrange monsters to high bandwidth cream pies with that je ne sais quoi beryllium is famous for. Still, they're nowhere near Focal, Revel or Magico Beryllium equipped offerings I've heard. The quad tweeter array does have an endearing quality as a result of its extremely high efficiency. It also has great bass extension for it's size and driver arrangement, the sealed box helps with that. The box itself is a modern masterpiece of machined and welded aluminum. This thing is a hefty beast for an in-wall speaker at 35lbs each. The bottom line is, the speaker is so poorly tuned from the factory, it requires serious correction. If I was going to redo this project from scratch, I would go with the Sonus Faber Palladio PL-664 or B&W CWM7.3S2 in that order. That said, Dirac Live is incredible.
