Unlike conventional speakers, the mid-range cones are rigid magnesium/aluminum constructions that reduce breakup problems. The new mid-range Z-flex surround smoothes the tweeter transition to the front baffle. Large voice coils increase power handling and dynamics, reducing distortion and delivering exceptional vocal clarity. Front baffles are clean with no visible screws. Grilles are fixed magnetically.

The R700 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 R700 floorstanding speaker also features two 6.5 inch low-frequency drivers above and below the Uni-Q array, which ensures a clean, deep and uncompressed bass output with superb dynamics. The R700 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 R700, resulting in a rigid connection that eliminates any rocking resonances.
