The kit includes all components and materials necessary to build a working pair of ESL III electrostatic loudspeakers. While enclosures are not supplied in this kit the instruction manual contains plans for 2 different cabinet designs. The PVC “pipe” enclosure shown on the Acorn ESL page can also be modified to suit this speaker for a quick and economical enclosure.

The enclosure on the right is simple to build and visually elegant. In larger rooms it may be necessary to integrate a sub-woofer to improve deep bass response.
