UNIQUE KHARMA ONLY ONE MADE OF BAMBOO

Newb to the speaker world and so need lots of advice.
Am getting a great deal on a mint pair of Kharma Grand Midi Ceramique 3.2
These are certified by Kharma to be the ONLY ones ever made of Bamboo.
Are they worth $17000?
Which amps would be suitable?

My room size is 14ft x 28ft.
Thanks
