Pregnant for thermal conduction kit

This speaker provided with the thermal conduction kit ensures the maintenance of the rods by a simple and practical clamping system to use. The pump (provided) produces a circulation of water from a thermostated bath (not provided) to the speaker. The end of the rods is thus maintained at a fixed temperature.
An additional speaker can be used in addition to the kit to maintain the other end of the rods at a constant temperature.
