Ludwig is the subwoofer in the range of WLM, the Wiener Lautsprecher Manufaktur from Austria, which builds loudspeakers and amplifiers.
Key specs that matter
Ludwig is an active design with a built-in amplifier rated at 1600 W. The rated response runs from 20 Hz to 150 Hz. The cabinet measures 65 x 24 x 35 cm and the unit weighs 15 kg, so the enclosure is relatively shallow and narrow for a subwoofer with this much amplification.
Pairing
With its own amplifier on board, Ludwig connects by line level to the sub out of a preamp, an AV receiver or an integrated amplifier.
