About the Bose Bass Module 700

Emily S.

Sound you can feel

I got to try the Bose Soundbar 700 on its own, and I was impressed with the amount of bass that slim sound bar could put out. But for the real lovers of rumble, Bose has created the Bass Module 700. In Bose's own words, “it's the difference between hearing bass and feeling thunder.” This bass module adds low-end impact to any model in Bose's Smart Soundbar lineup.

The Bose Bass Module 700 brings the thunder to your Soundbar 700 (sold separately).

Beautiful inside . . .

This subwoofer features QuietPort™ technology that aims to eliminate distortion while delivering powerful, dynamic bass. And if you run Bose's ADAPTiQ® room calibration system, the sound will be adjusted to suit the unique characteristics of your room. That way you get deep bass that's well-balanced, not overwhelming.  

. . . and out

Even if you crave the bass, it can be hard to give up living room real estate for a big, ugly box. Bose knows this, and they've given the Bass Module 700 a sophisticated look with a premium glass top panel. It's also wireless, so it's easy to tuck neatly anywhere within reach of an AC outlet.

Product Research


Bose Bass Module 700: The Bose Bass Module 700 has been designed to perfectly complement the Bose Soundbar 700 and Sounbar 900 (both sold separately). It also works with the Bose Soundbar 300, Soundbar 500, SoundTouch 300 (all sold separately). If you desire even more bass, you can wirelessly connect two Bose Bass Module 700s to a compatible Bose Soundbar speaker.

Wireless Connectivity: It connects wirelessly to the Bose Soundbar 500/700/900 and the SoundTouch 300. It has a wireless range of approximately 30'. The Bose Music App (for Apple iOS 12.0+ and Android OS 6.0+) is used to wirelessly connect the Bose Soundbar 500, 700, or 900 to the Bose Bass Module 700. The SoundTouch 300's remote control is used to make a wireless connection between the soundbar and the Bass Module 700.

Hardwired Input: If for some reason a wired connection is preferred, the Bose Bass Module 700 and the Bose Soundbar 500, 700, or 900 can be hardwired together using a standard 3.5mm audio cable. This is a proprietary mono-minijack 3.5mm hardwired connection and cannot be utilized with other brands or models of soundbars.

Placement: For best sound quality, the Bose Bass Module 700 should be placed on the floor against the same wall as the television and soundbar, with an electrical outlet nearby for the power cord. It should not be placed on a shelf or table. For more bass, the Base Module 700 should be placed closer to walls and corners. For less bass, the Bass Module 700 should be pulled away from walls and corners.

AC Power: The wireless powered sub requires AC power and comes with a detachable 5' AC power cord.

ADAPTiQ Audio Room Calibration: After you have positioned the Bose Base Module 700 in your room, plugged it into an AC power outlet, and connected it to your Bose Soundbar 500/700 or SoundTouch 300, you'll use the ADAPTiQ (headset supplied with soundbar speaker) to auto calibrate the system.

Optional Wireless Surrounds: In addition to the Bose Bass Module 700 and for a fully immersive sound experience, add the Bose Surround Speakers (sold separately) to your Bose Soundbar 500, 700, or 900.

Using the line-in this can be paired to any home theater ?

Greetings Jay, and thank you for your question. The Bose Bass Module 700 is proprietary for Bose sound bars. Even the 3.5mm jack uses their proprietary mono cable.
[ Thomas  Feb 22, 2023 ]  Staff
Can you use multiple of these on one sound bar?
[ Shilo  Oct 07, 2020 ]
1 answer
I do Remember reading that you can have two subwoofers to one sound bar. I have just one, couldn't imagine the bass with two. My advice would be start with one and add another later if needed.
[ JAMES  Oct 07, 2020 ]
How far from the sound bar can you place the subwoofer? (I'd like to place it across the room 16 feet) Would it work 16 feet away?
[ TIMOTHY W  Jan 14, 2020 ]
2 answers
Well, I'm not sure better ask the expert. Mine is only around 3' away from sound bar.
[ Gaudioso  Jan 19, 2020 ]
16 feet should not be a problem. I just moved my subwoofer 20 feet away and it still worked. Bose does not mention anywhere in its manual the max. Distance from sound bar to subwoofer. FYI-You can use a 3.5 mm jack to connect your subwoofer. Best placement of the subwoofer is 3 inches+ from the same wall as your sound bar.
[ Mark  Jan 14, 2020 ]
What size woofer is the sub?
[ Kevin  May 31, 2019 ]
2 answers
10 inches is the actual driver size. Note: The signal wire this "subwoofer" (it's not a subwoofer according to Bose) uses is a standard 3.5mm male-to-male audio cable, which is NOT provided by Bose as Bose relies on their bluetooth signal to send the audio to the device. If you want to use a physical signal, you will want to bring your own 3.5mm cable. Note: The audio fidelity is not a problem since this type of speaker is not meant to provide high quality (it's supposed to only provide "bass." That said, if you can get it to connect via BT, you're good and won't notice a difference. Note: If you're coming from a HiFi system with a traditional receiver, separate REAL subwoofer, Real satellite speakers (vs. sound bar), you will experience a huge difference and may not like this setup (sound bar and fake subwoofer combo). Note: Even w/ their 700 woofer, it's still very disconcerting for more people coming-off a traditional system (myself included and I'm returning the bar &both woofers I tried as a result). I'm not surprised, but I had to try and see if Bose created miracles... which they don't (although their on-ear & in-ear speakers are very good).
