Keel SE is the super evolution of Linn’s highest-performance LP12 sub-chassis.

With Keel SE, Linn’s engineers have comprehensively improved upon the original using Finite Element Analysis (FEA). Thanks to this revolutionary technology, Linn has been able to evaluate all limitations of previous sub-chassis designs and break free from them, using a combination of cutting-edge virtual prototyping and their own enhanced in-house machining capabilities. The outcome is a new and visibly improved machined sub-chassis with superior stiffness, optimised resonant behaviour, and ideal distribution of mass.

An intricate bracing structure machined into the underside of Keel SE – designed using a mixture of manual and computer-aided optimisations – has helped Linn achieve their number one goal of increasing sub-chassis stiffness as much as possible. This significant 300% increase versus previous designs means that any vibrations travelling through Keel SE have their frequencies forced higher, and their energy substantially lowered.

Optimised resonant behaviour allows Keel SE to better break up and dissipate problematic acoustic energy, reducing its potential impact on the delicate music signal.

By machining aluminium from calculated areas beneath the armboard, Keel SE has its centre of mass balanced more evenly on its suspension compared to other sub-chassis models. This improves weight distribution between the springs and reduces inertia, improving the critical acoustic isolation properties of any LP12.
