Overview

The Logitech Z323 is a 2.1 speaker system built around a simple idea: room-filling sound without a complicated setup. Each satellite speaker uses a dual-driver, front-and-back design that projects audio in 360 degrees, so the sweet spot is wide enough to share with someone sitting next to you. The down-firing subwoofer handles the low end, and the ported satellite enclosures are tuned to extend bass response further while keeping distortion in check. Together, the system pushes 30 watts RMS — 60 watts at peak — which is enough to comfortably fill a bedroom, dorm room, or home office.

Day-to-day usability is a strong point. The right satellite speaker puts power, volume, a headphone jack, and an auxiliary input within arm's reach, while the subwoofer's rear-mounted bass knob lets you dial in low-end intensity to taste. Two inputs — a 3.5mm and an RCA — can stay connected at the same time, making it easy to switch between a laptop and a phone or game console without swapping cables. As a renewed unit, this Z323 has been professionally inspected and tested for full functionality, offering the same audio performance at a lower price point than buying new.

Key Features

Z323 Speaker System lets you enjoy a rich audio experience from any direction. With a down-firing subwoofer for strong bass, bringing videos, games, and music to life.

360 Degrees of Great Sound - The dual-drive, front-and-back speaker design delivers 360 degrees of 30-watt sound, and 60 watts at peak power. That means great, booming, immersive sound from any vantage point.

Boosted Bass - The subwoofer and ported satellite speakers work together to give the bass plenty of power and a great sound. Satellite speakers feature an expertly tuned, ported design that delivers strong, distortion-free bass and an enhanced overall system balance.

Versatile Setup - Simultaneously connect two devices and switch between them. Just use the 0.14 in (3.5 mm) and RCA inputs to play, pause, switch—and keep playing.

Simple Controls - Get complete control at your fingertips. Easily adjust power and volume, plus auxiliary and headphone inputs on the right-hand speaker. Tweak bass with a dedicated knob on the back of the subwoofer.
