Manufacturer description

The Logitech Z625 is a THX-certified 2.1 speaker system built for people who want desktop audio that doesn't stop at the desk. Its 200 watts RMS / 400 watts peak output drives crisp mids and highs through the two satellites while the dedicated subwoofer handles the low end, so explosions in a game and bass lines in a track land with actual weight instead of thin buzz. What sets the Z625 apart from most 2.1 sets is input flexibility. Optical, 3.5mm, and RCA connections work simultaneously, so you can leave a game console, a television, and a PC all wired in at once and switch sources without…

SpecPicks Verdict

SpecPicks scored Logitech Z625 Powerful THX® Certified 2.1 Speaker System using a rating × review-volume × price-fit model applied to published specs and reviews across the accessories category. Logitech's accessories lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for accessories of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How loud does the Logitech Z625 actually get?

It is rated at 200 watts RMS and 400 watts peak, which is enough output to fill a bedroom or medium living room, not just a desktop. It is THX certified, meaning it passed THX's playback standards for clarity at volume.

Can I connect my PS5, TV, and PC at the same time?

Yes. The Z625 supports optical, 3.5mm, and RCA inputs simultaneously, so up to three compatible devices can stay connected at once. You do not need to unplug anything when switching between audio sources.

Does the Z625 have Bluetooth?

No. The Z625 is a wired system using optical, 3.5mm, and RCA connections only. If you need wireless streaming, you would need to add a separate Bluetooth receiver on one of the analog inputs.

Where are the volume and bass controls?

All controls sit on the right satellite speaker: power, volume, bass level, a headphone jack, and an auxiliary jack. That means bass adjustment is a physical dial rather than a software setting.

Is the Z625 worth it for gaming specifically?

It is built around gaming-grade audio with THX certification and a subwoofer for low-end impact, and the optical input handles console output directly. Broad satisfaction across gaming, movie, and music use is evident in its positive reception.
