With the two different finishes, black painted and polished silver, it perfectly fits the design of our turntables. Record pucks use weight to secure a playing vinyl record against the turntable platter. By holding the two together, the sound performance of the turntable will improve, in timing and depth of sound. With a weight of 190 grams, this puck is perfect for smaller turntables in order not to burden the turntable bearing and to prevent an increase in rumbling.
