Aquí tienes el test completo (en polaco) y aunque cuesta un poco distinguir los números, se puede deducir que las cifras que he comentado son correctas.

Y por cierto, hablando del "sufrimiento" de la clase D con las impedancias bajas, no hay mas que comentar que el 99% de las etapas que equipan los subwoofers son de clase D... y con las frecuencias que trabajan ya se deduce que es una buena tortura de impedancias.

Bueno pero los subwoofers tienen varios cientos de potencia de vatios, a veces más de 1000w, nada que ver con una etapa de 150W en Clase D. No sé, quizá sea un mito que deba enterrar, pero leo estas cosas y me echa para atrás la clase D:

"It’s also possible that the class D amp doesn’t like the 2.5 Ohm impedance minimum of the 948. However, the Focal shows true harmony and extended listening will never be a problem. This is a system for a music lover who has plenty of time to enjoy it."

The above graph shows the electrical behavior of the Focal Aria K2 936. Focal specifies this speaker to have a nominal impedance of 8 ohms, and that seems like a stretch. This is very much a 4-ohm load; in fact, the minima drops well below 4 ohms by my measurement. I would say Focal’s spec is there as reassurance that regular AVRs can handle this load. They probably could, but with a steep phase angle at the minima at around 100Hz, a very heavily used frequency, I wouldn’t want to crank these speakers on any AVR that cheaped out on the amplifier section. These speakers should be used with a stout amplifier

My estimate of the Focal's voltage sensitivity was 89.5dB(B)/2.83V/m—close to the specified 90dB, and usefully a little higher than average. The Aria 936 is specified as having a nominal impedance of 8 ohms and a minimum impedance of 2.8 ohms; my measurement (fig.1) confirmed the minimum value at 108Hz, but as the impedance stays below 4 ohms from the upper bass though the lower midrange, where music has high levels of energy, I would recommended using a amplifier rated into 4 ohms with this speaker.
