Which Sony systems is the BRAVIA Theater Sub 7 compatible with?

The BRAVIA Theater Sub 7 is designed to expand select Sony systems, including BRAVIA Theater Quad, Bar 9, Bar 8, Bar 7, and the HT-A7000, HT-A5000, and HT-A3000. It is intended as an additional wireless subwoofer for these Sony home theater and soundbar systems, not as a standalone subwoofer for any AV receiver.

How does the BRAVIA Theater Sub 7 connect to my system?

The Sub 7 connects wirelessly to compatible Sony soundbars and systems, so no physical audio cable is needed. Setup and control are handled through the Sony | BRAVIA Connect smartphone app, with the app and product connected to the same home network.

What kind of bass performance does the Sub 7 deliver?

The Sub 7 delivers 100 W of deep bass from a powerful 130mm driver with a bass reflex design. Its Separated Notch Edge surround improves diaphragm movement symmetry for deeper, clearer, and more controlled, distortion-free bass.

What is Separated Notch Edge?

Separated Notch Edge improves vertical amplitude symmetry using concentric cuts on the rubber speaker surround, helping control the stress inside and outside the edge of the diaphragm. The result is clearer, deeper, and more controlled bass.

Can I use two BRAVIA Theater Sub 7 units together?

Yes. You can connect two Sub 7 units for stronger, more balanced, room-filling bass. Dual-subwoofer use requires that your main soundbar or home theater system also supports pairing and dual-sub compatibility, and both subwoofers must be the same model.

How is the Sub 7 designed to fit into my room?

The Sub 7 has a slim, low-profile form factor with a versatile design meant to blend into different home setups. It supports dual-orientation placement, so it can be positioned vertically or horizontally to fit in cabinets, along walls, or under furniture.

Does the BRAVIA Theater Sub 7 have any power-saving features?

Yes. It uses about 20 W when on, drops to 1.8 W or less in network standby, and 0.3 W when off. Auto Standby engages after roughly 20 minutes with no signal.

How much does the BRAVIA Theater Sub 7 cost?

MSRP is listed as $329.99. Given that, these models can go on sale from time to time, and there are several other opportunities to save on price like through their group discounts for education, healthcare and military/veterans (ID.me & Unidays) along with their free loyalty program that gives up to 5% back in points.
