Rated 5 out of 5 by from This is the Sony Sub I needed I am very pleased with this subwoofer. I had the previous entry-level version of the Sub 3, which had no bass at all, and was hesitant on the Sub-5 because of the fact that it was probably mediocre as well. Although I have the BAR9 and the RS5 for the rear, the key area Sony skimped on was bass in the sub. In purchasing this one, I was reluctant, however. Upon arrival, from the sheer weight of it, I knew it was something special. And once connected, I played Mad Max & Sinners. It floored me.The frequencies get that sub bass for real-Low. And it's meaty, creamy. Clean base. Period. Music sounds fantastic as well. It's not the type of base that gives you a headache. It's the type of base that you feel. I sat on the actual sub9, and I could not feel it move at all, except for the air coming through the opening. It's sturdy. Period. If you are in the market for it and have the Bar 9, Bar 8, or whatever, the older A5000 or 7000, this subwoofer will satisfy mostly any need. The beautiful part about it is, if one doesn't do it, you can add a second one if you have one of the soundbars that are currently out from the 7, 8, or the 9 Bar. It would be nice to have a second one, but my room isn't that big, and it's not necessary, but it's nice to know you can do it. So having said all of this, I just want to make it clear that I'm sure people will be looking to see if this was a worthy investment although it wasn't necessarily a need, it was just for my personal satisfaction in the bass dept. To not wonder about Sonos or any of the others- if they were better. And patience has paid off. I am now satisfied. The price isn't super high when you look at Sonos and everyone else, but this subwoofer is truly, truly quality and worthy of a bass heads ultimate desire. Its a wonderful upgrade that I look to enjoy for some time to come!

Rated 5 out of 5 by from Absolutely Blown Away Not going to be long in the tooth on this one... I paired this with the Bravia Theater Quad and was quite simply blown away by the clean, impactful bass that came out of this sub. I was so impressed I just ordered a second to double the impact for my theater room setup. A 132" screen deserves sound this phenomenal! Looks are subjective, but I feel like this sub definitely steps up the wow in appearance. I personally feel like it makes their other subs look cheap. Then there's the weight... this thing is heavy which lends to it's high quality feel. I am also coming into this from a Theater Bar 9 paired with RS5's and SW5 with center channel sync out of my 65" Bravia 8 II. The quad with just one Sub 9 is a night and day difference and worth the cost of admission if you have the disposable funds to make it part of your setup.
