Our take on the Sony BRAVIA Theatre Sub 8

The BRAVIA Theatre Sub 8 is Sony's standalone wireless subwoofer for its soundbars and BRAVIA TVs, built around a 200 mm driver and a 300 W S-Master digital amplifier. It adds the low end that slim soundbars cannot produce, and it can pair with a second Sub 8 for a dual-subwoofer setup. It suits owners of a Sony soundbar or BRAVIA TV who want deeper bass without a full system upgrade. Against rival subwoofers it is compact for a 12.2 kg cabinet and connects directly to BRAVIA sets, though it is a one-channel design and adds nothing above the bass range.

Pros
  • 200 mm driver and 300 W amplification give real output for its size
  • Direct wireless pairing with BRAVIA TVs and Sony soundbars
  • Supports two Sub 8 units for a dual-subwoofer configuration
  • Compact 390 x 400 x 170 mm cabinet fits beside most furniture
  • Low standby draw at 0.3 W
Cons

Questions and answers

Does the Sub 8 work with non-Sony soundbars?
It is designed for Sony soundbars and BRAVIA TVs, where pairing is direct and wireless. With other brands it generally will not connect, so check compatibility before buying.
Can I use two Sub 8 units together?
Yes. The Sub 8 supports a dual-subwoofer setup, so a second unit can be added for more even bass across a larger room.
How big is the cabinet?
It measures 390 x 400 x 170 mm and weighs 12.2 kg. That is compact enough to sit beside a sofa or TV stand, but plan for the weight when placing it.
Does it need a wired connection to the TV?
No. It connects wirelessly to compatible BRAVIA TVs and Sony soundbars, so only power is needed at its position.
Is it worth adding if my soundbar already has a subwoofer?
If you want more output or a second sub for a larger room, yes. If your current bass is adequate, the gain will be modest.
