The RS 1.0 tweeter features a low mass, fine-weave soft dome diaphragm to transfer sound energy from the voice coil to the listener. This dome-design ensures a smooth frequency response from the low resonant frequency of the driver.

The compact and yet sonically versatile RS 3.0 is a 3.0-inch midrange driver perfect for active 3-way systems where space is mounting applications are at a premium. With a 1.38-inch mounting depth, small format custom cast chassis design and precision designed components the RS3.0 is the perfect match when space restrictions are at an all-time high for any reference audio or competition audio system.

The RS 4.0 provides increased power handling and low-frequency extension and requires a mounting depth of only 1.94 inches. Much like the RS3.0, the RS4.0 uses a hard-pressed composite woven/ papyrus damped paper cone designs. This composite design delivers a low-mass speaker cone with exceptional strength and excellent damping characteristics for smooth and natural sound reproduction across an extremely wide band of frequencies making this a very wide band capable speaker.

The RS 6.0 shares many of the same design characteristics and features of the midrange drivers, but with optimization for the higher excursion requirements commonly associated with reproducing bass and mid-bass frequencies. With a mounting depth of 2-3/4 inches, it maximizes the benefit of its high-strength neodymium motor in an efficient and yet low-profile design. Unlike the motors in the RS 3.0 and RS 4.0 Magnetic flux is controlled by an extended copper sleeve for exceptional clarity and greatly increased overall bandwidth.
