QUATTRO, built by James/US

I have enclosed some photos of the finished loudspeakers. I merely finished them, Richard did the most difficult part in building the cabinets.
(Okay, I suppose designing the woofer was also challenging...) The cabinets were constructed with solid Sapele, using internal birch plywood braces.
