Adam A7's (Europe)

The A7X are slightly bigger, have two ports instead of one, a renewed ribbon tweeter and the woofer is 7" instead of 6,5" big.
The frequency response goes from 42Hz to 50k Hz, while the A7 had 46Hz-35kHz.

The A3X,A5X,A7X and A8X had some port noise issues, though. Not sure if that's fixed by now.
