The eight‑inch bass/mid driver is custom‑made, utilising a polymer cone in a flexible rubber surround. A high‑temperature, one‑inch aluminium voice coil provides the drive, and a shielding magnet reduces stray magnetic fields, so the Circle 5s may be used close to video equipment. 

Direct replacement for the HHB Circle 5 mid/bass drive unit. Each drive unit is hand-assembled and tested at the Harbeth factory before shipping.
