Adding subwoofers to a high-performance audio system has often meant accepting a degree of compromise in timing and coherence, but the Linn Exaktbox Sub changes that equation. Purpose-built for seamless integration within an Exakt ecosystem, it applies precision digital crossover technology and phase-linear correction down to 0 Hz, allowing any subwoofer to lock in with the main loudspeakers without sacrificing the musical whole. The result is deeper, more articulate bass that feels like a natural extension of the full-range presentation rather than a separate effect.
Inside its discreet, low-profile chassis, the Exaktbox Sub houses two channels of Akurate-level Exakt conversion and a Linn Dynamik switch-mode power supply. Dual balanced XLR and unbalanced phono outputs support flexible configurations—from discrete left and right channels using a pair of subwoofers to mono or stereo connections for a single cabinet. Because the unit accounts for the physical placement of each speaker and the associated time-of-flight differences, the system maintains precise alignment at the listening position. It is a solution for those who want greater low-frequency authority without disturbing the timing and transparency that define an Exakt system.
