Keel SE is the super evolution of Linn's highest-performance LP12 sub-chassis.
In 2006, Keel broke new ground with its precision-engineered design – and has been intrinsic to the performance of Klimax LP12 ever since.
With Keel SE, Linn have comprehensively improved upon its precursor using Finite Element Analysis (FEA). Thanks to this revolutionary technology, their engineers have evaluated all limitations of the original Keel, and broken free from them using cutting-edge virtual prototyping and Linn's 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.
The bracing structure on 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 means that any vibrations that travel through Keel SE have their frequencies forced higher and their amplitudes substantially lowered.
To achieve this dramatic reduction in vibrational energy, Linn engineered Keel SE’s first mode of resonance to sit much higher than the original model – 500Hz versus 180Hz in the latter. Specific bracing in the design addresses several modes above this to break up and dissipate problematic acoustic energy across the spectrum, reducing its potential impact on the delicate music signal.
Keel SE has had rigidity and mass increased precisely where it is needed, with particular focus on the vital path between the mounting point for Karousel and the tonearm collar. The area between these has been stiffened up greatly. Even the slightest rocking movement of a sub-chassis and armboard will modify the physical relationship between tonearm and platter, negatively affecting the stylus’ tracking. Stiffening this area means any change in geometry is minimised, reducing tracking distortion.
