Changing speakers is the solution kindly offered by audiophile brethren. Thank you - I will.
Regarding the original post, so far nobody seems to find the dark humor in the "setup tips" from Zu.
Maybe is just me, but the "setup tips" seem to say to existing customers "you can't get any better. Please minimize disappointment. You got the Zu? Just live with it". But to someone who didn't already own the speakers, the video would say "they are what you wanted - regardless of your circumstances".
Interesting take on post-sales marketing. Post-sales, other companies might try to either a) actually help the customer, or b) get more money through upgrades, or c) simply pretend that the customer does not exist. Well - not Zu - the high-adrenaline marketing effort continues.
