New Klipsch Jubilee, with active crossover.

"...The 7” compressive (if I heard that right) driver is an interesting design element..."

Compression driver. It means the horn has a throat that is smaller than the driver element and the air helps load the driver element keeping distortion low in it's operating area. It also causes it's own distortion but it's a trade off for efficiency. 

Very exciting. I would love to hear them, or even better, to own them!

Klipsch website says 5” diaphragm. 7” seemed really large for a compression driver and also seemed large to be used as the mid/tweeter. JBL is using a duel 3” in their M2. It would be interesting to hear how they compare. 5” makes more sense but still seems very large. 

The advantage of having a single driver cover most of the frequency range should lead to good things assuming the highs are in control. I assume the active crossover is working it’s magic but I have to wonder if a 3 way would not have been better. 

This might be the driver in it. Link with measurement of the driver below.

The whole idea of the Jubilee is to make it a two way system where the top driver goes low enough to blend with the woofer section. It removes the crossover in the critical voice frequency range.
