Q: What is the total power output of this subwoofer?

A: This subwoofer has a total power output of 300W.

Q: Why is subwoofer so ridiculously expensive? $700 for just the subwoofer is ridiculous? Why are you such greedy scumbags?

A: I agree that this sub is very expensive. I purchased it in a package and received about a 200 discount. I have not yet set it up, but it sounds incredible in the cavernous Best Buy store and will be great in my family room. When you buy Sony, you buy the best.

Q: I purchased the Sony 7.1.2 sound bar and subwoofer Model HTST5000 on 8/4/2018 My subwoofer rattles and is distorted. Not sure why? I don't blast the sound to its capacity. Would the above subwoofer work with my current sound bar?

A: Switch to your soundbar input and hit "home" on the remote. Navigate to settings and look for the RF Optimization. Turn it off and then back on or if the issue keeps happening try leaving it off. This resets the bluetooth connection between the sub and/or satellite rear speakers and tends to clear up static/dropouts. I actually just leave it off now and have no issues.

    Unleashes the HTA7000 with clear and powerful bass

    I have the HTA7000 Soundbar and it is excellent overall as standalone. Adding this subwoofer releases the Soundbar from performing bass duties and delegates that to the Soundbar. The Soundbar will now allow more subwoofer audio levels going from only 3, to more than 10. This allows the Soundbar to provide the cleanest audio along with bass. Without the subwoofer the Soundbar can produce decent bass at the cost of introducing muddiness when cranking the bass levels to high. The addition of this subwoofer the muddiness goes away. The audio from the subwoofer is excellent. It provides deep bass that fills the room. I placed the subwoofer next to my couch, basically on the opposite side of the TV and Soundbar wall. I was worried about this not being optimal placement but it worked well. The room fills with powerful bass. The subwoofer box has excellent build quality with sof touch materials all around. There is a front firing and also a downfiring driver. It only uses 43w of electricity and automatically connected with the Soundbar when plugged in. It is about 12 feet away from the Soundbar and there have not been any wireless connection issues. If you don't have a preference for a TV I would highly recommend pairing up the Sony Soundbar with a new bravia TV because the TV remote can fully control the Soundbar and there will be no requirement to have multiple remotes. The Soundbar, sub, and rear surrounds turn off and enter standby mode when the TV is turned off and they turn on she the TV is turned on. It is great that the sony ecosystem fully integrates itself with Soundbar options available on the TV's quick menu system.

    Deep, Punchy Bass That Perfectly Complements Sony

    I recently added the Sony SA-SW5 300 W Subwoofer to my home entertainment setup featuring the Sony BRAVIA 8 II 65-inch TV and the Sony QUAD sound system, and it has made a tremendous difference in overall audio immersion. The 300 W output delivers powerful, deep low frequencies that are tight and articulate, without muddiness—even at higher volumes. Action scenes on the BRAVIA 8 II feel more explosive, musical soundtracks have a fuller presence, and gaming experiences come alive with rich bass impact. The combination of the Sony QUAD’s spatial sound and the SA-SW5’s deep bass creates a truly cinematic soundstage. Integration with both the BRAVIA 8 II and Sony QUAD was seamless. The automatic calibration and wireless connectivity made setup easy, and the subwoofer synced perfectly with the existing system. Having the low end handled by the SA-SW5 allows the Sony QUAD speakers to focus on clarity and detail, resulting in balanced, full-range sound that enhances every type of content. The build quality feels solid and premium, and the overall performance exceeds expectations for a subwoofer in this class. If you own a Sony BRAVIA 8 II and Sony QUAD setup, adding the SA-SW5 elevates your home theater experience to the next level. Highly recommended for anyone looking to complete their audio system with rich, immersive bass.

    Thumping, clean bass

    Paired this with my HT-a7000 sound bar and RS5 surround speakers. This sub is a beast. I have it set to less than half the max output and it sounds great. If I didnt live in a townhouse with shared walls I'd probably have it cranked up higher. Its a little pricey, i got a really good deal on it when bundled with my whole system though. If you can get it at a discount, donit. You wont be disappointed with its performance!
