Leather!?
"Sorry Bill, can't go out tonight. Gotta stay home and moisturize my speakers!"
That said, that is a very aggressive price point for them! I hope the use of leather is enabling them to save in production costs over woodworking and endless days of clear coating. Having worked with leather, I hope its thick enough and that they padded the edges where they hide the seams so that over time, and a careless owner, won't see those edges start to discolor or crack!
I'd offer a sample of Dax Lanolin to go with it! Best leather moisturizer period!
