Higher ratedRanked #1 in Best Computer Speakers with Subwoofer

Klipsch ProMedia 2.1 THX

4.7

$200

The ProMedia 2.1 THX is the best-overall pick. Two decades of Klipsch refinement on a desktop 2.1 — horn-loaded upper mids plus a 6.5" sub deliver gaming and movie impact nothing in this lineup matches at the price.

Strengths

— THX-certified — first computer speaker system to receive THX certification, two decades on
— MicroTractrix horns deliver impactful upper-mid presence
— 200W peak power + 6.5" side-firing ported subwoofer for room-shaking bass

Watch-outs

— No Bluetooth — wired-only (3.5mm or RCA)
— Sub is large and demands floor placement
— Voicing is bright/forward — vocal-heavy listeners may prefer the Logitech Z407
