Yesterday, I got to play around with a superb compact speaker set-up from Nexo; the Nexo PS-8 w/matching subs, and powered by the 4 channel Nexo NXamp amplifier/processor. The tops weigh just under 17 lbs. Good Lord this thing sounded good. System cost, including the 4-ch amp, was $9k, and there's "wiggle room" on that price. The 4ch. amp is not necessary of course, and it was actually borrowed from another Nexo display at the store. The amp goes for $4k. The 12" sub, weighs in at 43 lbs.
I also listened to a demo of some much larger Nexo systems as well. Brutal output, and clear as a bell. The 4-channel amps are a bit power-hungry to say the least, with each amp requiring two 30amp circuits.
