The enclosures for the speakers shown in the photo section are for sale. The one on the left is a very nice bass reflex box that works well for vintage 8" full-range drivers. They currently house Tru-Sonic FR80 drivers but will work with Altec 755s. They are covered in really nice rift white oak veneer with a lacquer finish. They are $50 without the drivers.
The one on the right is the Brother Jon transmission line speaker designed for Focal drivers. It is made of plain MDF and currently houses Fostex 225K 8" full ranges. They are $20 without the drivers. Buy the oak ones and get these free.
