The R300 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 R300 bookshelf speaker also features a 6.5 inch low-frequency driver below the Uni-Q array, which ensures a clean, deep and uncompressed bass output with superb dynamics.
Surrounding the Uni-Q driver array is our new mid-range Z-flex surround, which projects audio more efficiently into your listening space and results in undistorted high frequencies.

The R100 features a 5.25 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.
Surrounding the Uni-Q driver array is our new mid-range Z-flex surround, which projects audio more efficiently into your listening space and results in undistorted high frequencies.
The R100 affords you the option to use either a single amplifier as your source, or to bring in a second amplifier to handle certain frequencies.

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.

The Q500 features a specially-voiced 5.25 inch aluminum Uni-Q driver and 1 inch vented aluminium dome tweeter.
Based on our state-of-the-art HF driver, the Q500 boasts a much larger dome tweeter for increased sensitivity and distortion-free power handling.
Below the Uni-Q driver array are three stacked 5.25 inch bass drivers working in tandem to quickly and efficiently produce a range of low frequencies.

The R400b uses two ultra-low distortion 9 inches bass drivers, each braced with force-cancelling technology within the cabinet to allow both drive units to operate more effectively, giving greater definition to low frequencies.
The shape and bracing of the cabinet are computer optimized to minimize secondary radiation from the cabinet walls and distortion from standing waves.
Measuring a compact 14 inches deep and wide, the R400b delivers a surprisingly massive low-end with an incredibly quick response.
