The Sony SRSZ100 is a computer speaker system outfitted with two 57mm speakers that output a total of 20w of power. The third of four Sony SRS models, the SRSZ100 switches pace from its predecessors (the SRSD25 and SRSDF30) in that it trades a 2.1 channel system in favor of merely two speakers. Despite the SRSZ100’s lack of a subwoofer, it should be noted that each speaker packs a mid-range driver with a reflex port for an enhanced bass response, not to mention a tweeter for sharp high frequencies. In addition, the SRSZ100 sports magnetic shielding for reduced interference, a mega bass function for loud-thumping bass, a headphone jack, and 2 analog inputs for a PC as well as other portable units. The Sony SRSZ100 retails for $99.99 and comes with a 90 day limited warranty.
