One of my FHXL customers asked me to cut the wood for this speaker enclosure. After he assembled the speakers he compared them to his existing B&W 603s and was floored at the quality of sound that the Halcyons produced. In his words “the B&W sound like cardboard boxes.” You can read his build thread and listening impressions here, and visit the designer’s (Curt Campbell) webpage for this design.
This kit includes only the wooden parts to build the enclosure. Parts are cut from 18mm Baltic Birch plywood and will be cut for the terminal cup/location of your choice. Madisound sells the drivers, crossovers, and other items in a kit here. You will need to go to the hardware store to get your own sonotubes.
