Kitten Koffins

Near-field Reference Monitors

Designed by Sarah Calvert

The Kitten Koffins are near-field reference monitors that incorporate a unique shape size that produces a wide dispersion of sound. The coffin cabinet is an excellent shape for producing a flat and even frequency response. Both of which were very important goals of my design.

Due to being a sealed speaker and their smaller shape, the Kitten Koffins have an F3 of about 70hz. They are 13 inches in height and just over 14 inches in depth. Because of the angled shape on the front of the speaker, the width is roughly 10.5 inches. I designed them smaller and to incorporate a subwoofer with the system.
