Short answer: the Logitech Z623. It ranks #5 of 8 powered subwoofer and satellite combo speakers by sound quality, rated 3.2/5, at $172.89. The Logitech Z407 ranks #6, rated 3.0/5, at $115.50, $57.39 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the Logitech Z623: A high-output 200W RMS / 400W peak THX-certified 2.1 system engineered for room-filling PC gaming, movie watching, and party playback. The tradeoff: The acoustic tuning prioritizes visceral bass impact and energetic highs over audiophile midrange neutrality, resulting in a somewhat scooped frequency response.
Why pick the Logitech Z407: A modern 40W RMS / 80W peak 2.1 desktop system featuring dual-orientation satellite speakers (vertical or horizontal under-monitor) and a 4-inch down-firing ported subwoofer. The tradeoff: The 4-inch subwoofer driver delivers pleasant desktop warmth but cannot match the deep sub-bass authority or high-volume composure of larger 6.5-inch or 8-inch systems.
Buy the Logitech Z623. It is rated higher for sound quality, and the $57.39 you would save on the Logitech Z407 does not close the gap.

Logitech Z623: $172.89 Amazon eBay
Pros: A high-output 200W RMS / 400W peak THX-certified 2.1 system engineered for room-filling PC gaming, movie watching, and party playback. Features a massive 7-inch front-firing ported subwoofer that delivers physical, chest-thumping low-end impact down to approximately 35Hz. Supports simultaneous multi-device connectivity via RCA and dual 3.5mm inputs, with convenient on-satellite power, volume, and dedicated bass level controls alongside an integrated headphone jack.
Cons: The acoustic tuning prioritizes visceral bass impact and energetic highs over audiophile midrange neutrality, resulting in a somewhat scooped frequency response. Satellites use single full-range drivers without dedicated tweeters. Lacks Bluetooth or digital inputs in this standard configuration.

Logitech Z407: $115.50 Amazon eBay
Pros: A modern 40W RMS / 80W peak 2.1 desktop system featuring dual-orientation satellite speakers (vertical or horizontal under-monitor) and a 4-inch down-firing ported subwoofer. Its standout feature is a wireless 20-meter rotary control dial that provides smooth, tactile control over volume, bass level, play/pause, and track skip from anywhere on the desk. Highly flexible triple-input connectivity includes micro-USB digital audio, 3.5mm analog aux, and Bluetooth 5.0 wireless streaming.
Cons: The 4-inch subwoofer driver delivers pleasant desktop warmth but cannot match the deep sub-bass authority or high-volume composure of larger 6.5-inch or 8-inch systems. Small single-driver satellites exhibit limited dispersion and treble extension above 15kHz.
