The R500 features a 5 inch Uni-Q driver array, which consists of both mid-and-high-frequency drivers. The purpose of the array is to have both frequencies coming from the same place, allowing them to integrate perfectly and create a convincingly natural sound. The R500 floorstanding speaker also features two 5.25 inch low-frequency drivers above and below the Uni-Q array, which ensures a clean, deep and uncompressed bass output with superb dynamics. The R500 sits on an aluminum plate supported by four steel "plinth" spikes with locking knobs for easy height adjustment. The plinths also serve to ground the R500, resulting in a rigid connection that eliminates any rocking resonances.
