Founder 40B

2-driver, 2 way standmount, ported enclosure

Features & Specifications

During our exhaustive research, design, and engineering process, we looked closely and carefully at how speakers interact with their environment. The contemporary home interior presents design challenges that have become even more prominent over the last decade. Stone, glass, and wood have become the materials of choice and open concepts dominate. Founder’s design has evolved with this trend and is perfectly suited to deliver its maximum performance in rooms that would challenge traditionally designed speakers. Whether you enjoy movies and music in a more traditional listening space, or your home is from the pages of Architectural Digest, you can be sure Founder will sound as good as they look.
