Logitech Z407 vs Logitech Z623

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Logitech Z623 comes out ahead by a narrow margin (4.4 vs 4.6). The gap is mostly about gamers on a budget who want THX certification without paying ProMedia prices — read the strengths below before deciding.

Ranked #4 in Best Computer Speakers with Subwoofer

$130

The Z407 is the modern flexibility pick. Bluetooth plus wireless control puck plus USB input — the only pick that connects seamlessly to phones and laptops without cables. Less raw power than the Klipsch and Z623 / Z906, but the right buy for hybrid work/play desks.

Strengths
  • Bluetooth 5.0 — only Bluetooth-equipped pick here
  • Wireless desktop control puck for volume + bass + Bluetooth pairing
  • Modern-looking aesthetic — fits better with newer desk setups than aged Z623
Watch-outs
  • 80W peak power — less than every other pick
  • Sub is smaller than Klipsch ProMedia 2.1 or Logitech Z623
  • Voicing tuned for music rather than gaming impact

The Z623 is the budget THX pick. Same THX-certified standard as the Klipsch ProMedia 2.1 at $50 less, with multiple inputs. Aging design means no Bluetooth — wired-only setup. Best for gamers on a tighter budget.

Strengths
  • THX-certified — same standard as the Klipsch ProMedia 2.1 at lower price
  • 200W RMS / 400W peak total power
  • Three inputs (RCA + 3.5mm × 2) — connect computer, TV, console simultaneously
Watch-outs
  • Aging design (released 2011) — no Bluetooth, no modern features
  • Volume / bass / treble knobs on the right satellite can be inconvenient to reach
  • Top end less detailed than the Klipsch ProMedia 2.1
