Never Heard Anything Like It
I bought this from Sony before Christmas, they got it to me quickly and registered it for me, I got it to supplement my Sony HT-A9 cinema sound system. The reviews were universally excellent and said it married well with the HT-A9, I hadn't connected it to power at first then when I did I found myself in slight shock, realising that something I routinely run through my system is actually meant to sound completely differently to the way it has before, this is true of my HT-A9, all my content is being acoustically rediscovered slowly, I can honestly say I've never had that before. If you want get the best quality, the reference home cinema sound for the next decade, look no further than Sony.

Great sub
I’m my opinion this sub is a must. Gives off plenty of bass and gives films and music the depth that they need.
I bought this to accompany the HT-A9 system. I was advised by multiple sources online not to even bother with the smaller sub and I’m glad I followed their advice.

Bassey subwoofer
I had my eye on this subwoofer and the home theatre bundle for a while. It hits low bass and has a wide as well as immersive reach. A great product which fits into my living room conspicuously. I love this subwoofer.

Well, what can I say - outstanding job Sony!
This subwoofer is an absolute must for your latest Sony Soundbars!

Sony has been very kind providing HT-A5000 soundbar for me to test, it's a great product on it's own! But having additional accessories as Sony SA-SW5 subwoofer and Sony SA-RS5 rear Atmos speakers are a game changer!

The quality of bass is superior, there is no distortion, clear, steady, punchy low bass.
Seamless connectivity and stable connection to the soundbar.
Built quality is exceptional.

I highly recommend this product as additional accessory for Sony HT-A7000 and HT-A5000 soundbars.

My personal opinion:
I wouldn't waste extra £300 GBP on top of the range HT-A7000 soundbar, but instead would buy Sony HT-A5000 and add soundbar and Atmos rear speakers!

Sony should include this subwoofer to all new soundbars, as it's incredible product.

Great Addition to HT-A9
As others have said, HT-A9 sounds great on its own. BUT, wait until you have this subwoofer. The difference it makes is mindblowing. Being wireless, you can place it at the correct place in the room for the best bass reproduction, provided that you have a power point nearby.
