You’re correct, he states in his auction, “I forgot to mention that in each speaker, 1 woofer has been replaced with a Morel Ultimo subwoofer, making them sound even more amazing. Woofers cost $2000 by themselves.”
Seems wrong to put those woofers in them and do they cost that much? He’s trying to sell them and stating what he thinks will help them to get sold.
What does Klipsch sell a pair of these for?
