Quick verdict
Start with SA-SW3 for a compatible Sony system when space, moderate listening levels and total cost matter most. Consider SA-SW5 when bass impact is a priority and the larger purchase fits both the room and budget. Published wattage alone cannot establish the better result at your seat.
This comparison uses the manufacturer sources linked below and practical buying criteria. It does not claim a controlled hands-on test or original performance measurements.

What Sony actually publishes
Sony lists a 160 mm driver and 200 W output for SA-SW3, compared with a 180 mm driver and 300 W for SA-SW5. These are documented design specifications, not measurements of maximum output or extension taken for this guide.
Do not translate 300 versus 200 W into fifty percent more audible bass. Room response, placement, listening level and the rest of the system affect the result. Look for useful capability rather than a simple arithmetic sound-quality ranking.
Measure the floor space before upgrading
SA-SW3’s published cabinet measures 201 × 382.5 × 402 mm. Check the full measurements of either model against the actual position, including clearance and access to power. A subwoofer that fits only inside an unsuitable enclosed cabinet is a poor purchase.
Try a small number of practical positions during setup, following the manufacturer’s guidance. A position that looks tidy can sound different from another position nearby. Keep the listening level consistent when comparing changes.
Compatibility comes before performance
These are optional wireless subwoofers for supported Sony audio systems. Use Sony’s current compatibility table to check your exact soundbar. A wireless connection label does not make them universal accessories for an unrelated soundbar or a TV’s Bluetooth output.
If you plan to replace the soundbar later, check the intended next system as well. Buying a subwoofer for an uncertain future combination can lock money into an accessory you cannot use.
Who should spend more
Consider SA-SW5 if you regularly enjoy bass-heavy films, have a suitable location and want to compare the larger model at the levels you will use. It is less compelling if you mostly watch dialogue-led television quietly in a shared building.
SA-SW3 is a reasonable value candidate when the goal is adding missing low-end weight rather than maximum impact. Neither model removes the need to set a considerate bass level or account for sound transmission to neighbouring rooms.
Final choice
Choose the subwoofer that gives the result you want without overwhelming the budget or placement options. For many moderate-volume systems, starting smaller is the more measured purchase; the larger model needs a benefit you can use.
If your present subwoofer already sounds satisfying, keep it. Spend on the upgrade only after identifying the limitation you want to address, and check delivery, return terms and the exact regional product listing.
