Strictly for bragging rights, not for real music listeners IMO. I suppose all that gold is a good hedge against a drop in the stock market when we have a nuclear war.
I have Vapor Audio Nimbus and I don't care if I win the lottery, these are my speakers to stay!!
With that massive 3 inch woofer and class D amps, the 5 million dollar price appears to be fair; you do also get 132lbs of gold and a few diamonds, I hope you do appreciate that.
At today's spot gold price of $1,319 per ounce the gold content ($1,319 X 16 X 132) = $2,785,728. So if we melt down the gold we are left with the awesome high-end audio power of a 3" cone driven by a Class D amp -- for a mere $2,214,272.
Oh, I guess the diamonds account for most of the balance of the price!
All-in-all this sounds to me like a true high-end bargain!
