The 'RubiKon' - LP12 Sub-Chassis
Download the spec sheet for the RubiKon here
The RubiKon is a sub-chassis for the Linn Sondek LP12. Born out of an idea over
a pint in a pub (Theakstons 'Black Sheep') it is designed from first principals
to be the best sub-chassis we could produce within the physical requirements of
an LP12. It uses constrained layer damping and separate structures for the arm and bearing
mounts. The construction method controls the resonant frequency of the various
sections allowing energy to be dissipated into the sub-chassis away from the
stylus contact point. The bearing mount is even thicker than that on the Linn ‘Cirkus’ sub-chassis allowing a stronger connection between bearing and sub chassis. The various parts are CNC cut from 6082-T6 grade aluminium which has excellent machining properties. The finished parts are hard satin black anodised, after being 'linished', to provide an immaculate fit and finish. The sub-chassis
and armboard sections are glued together individually; the whole structure is
then bolted together using stainless steel bolts to provide a rigid connection
between sub-chassis and armboard. The RubiKon is available with a standard Linn, NAIM ARO mount and Rega (RB versions); other mounts can be catered for. It will be sold through a selected number of
retailers. Armboards are interchangeable by your dealer allowing one to
upgrade/change a tonearm without having to buy a complete new sub chassis.
Improvements over a standard Linn pressed steel sub-chassis include better detail retrieval,
improved bass timbre and definition, larger soundstage and an overall
cohesiveness throughout the entire audio spectrum. Music is replayed with the
macro and micro dynamics intact. Loud instruments are layered over the top of
the tiniest detail without smothering them.
