Description

Link to section “Description”

In brief

A 2-way top with a 12-inch woofer and a 1.4-inch driver on an 80° × 60° horn, made from 15 mm birch plywood.

The F122AN is a 2-way full-range enclosure from the “Suggested designs” of B&C Speakers. It is fitted with the 12-inch neodymium woofer 12NW76 and the 1.4-inch compression driver DE820TN on the ME90 horn (80° × 60°).

The older B&C plans consist of a cover sheet and drawings; there is hardly any running text. The file is hosted on the former B&C domain, whose certificate has expired. We therefore link to the current “Suggested designs” overview page.
