The Linn Isobarik is a loudspeaker system that was introduced in the late 1970s by the Scottish audio manufacturer Linn Products. The design features a unique cabinet structure, which includes a stiffened enclosure to enhance speaker performance by reducing unwanted resonances. The Isobarik uses a coupled cavity design, where one driver is located behind another, allowing for a smaller front-facing driver to produce bass frequencies more efficiently. The Isobarik is known for its ability to reproduce detailed sound over a wide frequency range, and is often paired with high-quality amplification to maximize its potential. The speaker cabinet is made from high-density materials to ensure stability and accuracy in sound reproduction. Additionally, the original Isobarik includes a crossover network that is designed to seamlessly integrate the various drivers, resulting in a cohesive soundstage. Specifications include a frequency response range typically cited as 20 Hz to 20 kHz and an impedance of 8 ohms. The Isobarik design has been influential, and its basic concepts can be seen in various speakers that followed. Some variations exist, with updates to driver technology and cabinet materials over the years.
