Reftone is a Woodland Hills, California-based loudspeaker company founded by Dave Hampton and Lisa Chamblee, operating as Reftone Speakers LLC. The brand is built around classic reference-monitoring techniques — low-level and mono listening — aimed at engineers and producers who want to hear what a mix really sounds like before committing to it.

Its core lineup centers on the Ref-Cube family of single-driver nearfield monitors: the passive LD-3 and the powered LD-3B (a Bluetooth-equipped active version), both housed in sealed birch-plywood cabinets with 4-inch full-range drivers. Reftone also produces the LD-10, a drop-in replacement woofer designed for the Yamaha NS-10M, and the LD-2H headphones, extending the same reference-listening philosophy to other formats.

The company maintains a network of professional users it calls Reftone Pros, which has included mix engineer Dave Pensado and producers Terrace Martin and Larrance "Rance" Dopson.

Reftone has 5 products cataloged on Equipboard, including Active & Passive Monitors and Accessories.
