Unfortunately we are unable to offer much help in this instance as it is against company policy to divulge build information of any of our products past and present. We cannot provide schematic diagrams of crossovers, amp modules, cabinet designs or T&S parameters of our drivers.
While we understand that many Tannoy fans enjoy building their own loudspeakers as a hobby, or that some schematics may be required for repair, this has led to some trouble in the past which is why we have adopted this policy.
If you are in need of repair then we recommend that you contact your local Tannoy service agent.
For more information, please submit a query to a member of our support team.
