In a departure from previous models, the Boom combines Squeezebox functionality with a DSP, a 30 W [6] integrated amplifier and bi-amped stereo two-way speakers to produce a self-contained device which requires only a network connection (either wired or wireless) and power.
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts.The electrical power delivered to the loudspeaker, together with its efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat).
The equaliser, connected between pre-amplifier output and power amplifier input, effectively flattens the speaker frequency response. [26] Each speaker has nine identical 4-inch drivers per channel — one on the front for direct sound, and eight on the rear designed to produce reflected sound. [23] [27]
