Lots of deep, hard hitting bass

Marion from Charlotte, NC on 1/8/2018

Crutchfield Customer Review (What's this?)

Very loud deep bass. I added this to my HW-MS650 sound bar, with surround sound speakers, and I have to tell you, best 400 I've spent. Connected seamlessly, and has really deep hard hitting bass. It looks great sitting in the corner too, very simple design. I got this system to replace an energy sound bar system which was extremely loud but was not nearly as clear as the Samsung system that I've put together.

Pros: Lots of bass, but will not over saturate the sound of the sound bar, it will complement the sound without drowning it out. Very nice complement to system.

Cons: Can only add to listed devices, would be nice if this was capable of pairing with systems that cost a little less. You have to pay to play basically.

Great Sub Woofer

Greg from Hampstead, NC on 12/14/2017

Crutchfield Customer Review (What's this?)

Outstanding addition to my Samsung sound bar! Happy I spent the money!

Pros: Great bass in conjunction with Samsung sound bar

Cons: Couldn't get the first one to connect to the sound bar... returned and purchased from Crutchfield. Be patient in connecting to your sound bar and either call for assistance from seller or Samsung.

Samsung Sound+ SWA-W700

Robert from New York on 11/18/2017

I just added the sub to the ms750 .the unit is down in my basement and it makes the windows tattle. The soundbar alone can not produce the bass that i want.

Pros: Incredible sound .

Cons: Little pricey......should have waited for sales .

Compatibility: You can add Samsung's SWA-W700 wireless powered sub to a Samsung Sound+ series soundbar - like the HW-MS550, HW-MS560, HW-MS650, HW-MS651, HW-MS660, HW-MS661, HW-MS6500, HW-MS6501, HW-MS6510, HW-MS6511, HW-MS750, HW-MS751, HW-MS760, and HW-MS761 (all sold separately).

  • The included Wireless Dongle must be installed and connected to your compatible Samsung Sound+ series soundbar's proprietary "WIRELESS" port, in order for the soundbar speaker to send a wireless audio signal to the SWA-700 powered sub.
  • The Wireless Dongle that comes with the SWA-W700 can also be used in conjunction with Samsung's SWA-9000S Wireless Surround Kit (305SWA9KS, sold separately).

Wireless Connectivity: The Samsung SWA-W700 wirelessly pairs with your compatible Samsung Sound+ series soundbar. It has a wireless range of approximately 30'.

10" Woofer: The SWA-W700 wireless powered subwoofer is outfitted with a rear-firing 10" woofer in an acoustic suspension (sealed) enclosure for ultra-deep bass performance between 27Hz to 120Hz. The woofer cone is made of polypropylene, while the surround is made of rubber.

Seamless, Elegant Design:  Seamless front and back, the SWA-W700 is simple and elegant, with a timeless unibody design.

Power Requirements: The SWA-W700 wireless powered subwoofer comes with a detachable 5' AC power cord which will  need to be plugged into an AC wall outlet or surge protector (sold separately).
