RMS refers to Root Mean Square, which is a typical measurement of audio power, or rather, the electrical power transferred from an audio amplifier to a loudspeaker, which is measured in watts. The amount of electrical power delivered to the loudspeaker and its sensitivity determines the sound power that is generated. Essentially, amplifiers are limited by the electrical energy they can amplify and loudspeakers by the electrical energy they can convert into sound energy, without distorting the audio signal. The higher the wattage, the better the sound power emitted by the speaker.

Aluminium die casting is lightweight and can withstand higher temperatures. It offers great strength and rigidity, along with good corrosion resistance.

DAB (Digital Audio Broadcasting) digital radio is a new way of broadcasting radio, in addition to FM analogue transmission, via a network of terrestrial transmitters. It provides listeners with more choices and information delivered in clear, crackle-free sound quality. The technology allows the receiver to lock on to the strongest signal it can find. With DAB digital stations there are no frequencies to remember, and sets are tuned by station name, so there is no retuning on the move.
