Manufacturer description
The Logitech Z623 is a THX-certified 2.1 speaker system built for people who want their desk or living room to actually move air. Connectivity is the reason this Logitech system has stayed a retro-audio staple. RCA and 3.5mm inputs let you keep up to three sources plugged in at once: a PC, a game console, a DVD or Blu-ray player, a phone, or a tablet. Anything with a headphone jack or RCA output works, including PlayStation, Xbox, and Wii, so a single set of speakers can serve a modern desktop and a shelf of legacy hardware at the same time. The subwoofer measures 11.2 x 12.0 x 10.5 inches…
SpecPicks Verdict
SpecPicks scored Logitech Z623 400 Watt Home Speaker System using a rating × review-volume × price-fit model applied to published specs and reviews across the audio & midi category. Logitech's audio & midi lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
