SOUND
REFERENCE 8b
For power with accuracy the Reference 8b sub has two 500W Class D amplifiers, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver. These are connected back-to-back in a heavily braced, acoustically inert cabinet. The result is low distortion bass with effortless body and weight.
Simply power up and pair using Bluetooth 4.0 with aptX® for sensational cable-free audio. Or, if you want to unlock the potential of your computer based audio or TV sound, including hi-res, choose the micro-USB or optical inputs.
