Head-to-head
Sennheiser AMBEO Soundbar Mini vs Polk MagniFi Mini AX: Polk shrinks the bar but adds a powered floor box and more source options
The short answer
Choose AMBEO Mini when you want one enclosure and have a compatible HDMI audio-return connection. Choose MagniFi Mini AX for a much narrower main bar, an optical or analog source and a supplied subwoofer. Both offer Wi-Fi music, but Polk's compact bar still brings a second powered box into the room.
Before you choose
The reasoning and the trade-offs
Mini describes two different installations

What matters in practice
The differences that matter
Mini describes two different installations
AMBEO Mini minimizes the number of enclosures. Polk minimizes the bar's width while placing bass hardware in a second enclosure.
How we reached this conclusion
The verified AMBEO offer contains one bar. The Polk offer contains a bar and powered wireless subwoofer. These are different package layouts despite both using Mini in the name.
A 20-inch opening fits only Polk's bar
Polk leaves 5.6 inches of total width before placement clearance. AMBEO Mini's body exceeds the opening by about 7.56 inches.
How we reached this conclusion
20 - 14.4 = 5.6 inches. 70 / 2.54 = 27.56 inches. 27.56 - 20 = 7.56 inches. The separate Polk subwoofer is outside this body-width calculation.
An optical-only TV makes the connector decisive
Polk provides a direct optical input, while AMBEO Mini's specified TV connection is HDMI eARC. Similar wireless music features do not solve that wired TV mismatch.
How we reached this conclusion
Polk's input table lists HDMI eARC, optical and analog 3.5 mm. The Sennheiser SB02 Mini input table lists HDMI TV eARC and a service USB port, without optical or analog audio.
Try your real numbers
Will the soundbar fit under your TV?
Measure the clear space in front of your TV. Count devices you want to plug into the soundbar, not devices already connected to the TV. The numbers below are examples until you enter yours.
Sennheiser AMBEO Soundbar Mini
Does not meet these checks0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
Polk MagniFi Mini AX
Does not meet these checksIts 3.1-inch height exceeds the 3 inches below your picture.
Use an open top surface, not an enclosed cubby. Detachable speakers are counted in the docked width. Allow extra depth for cables and the TV stand. This checks physical dimensions and port counts, not Dolby Atmos, 4K/120Hz passthrough or your TV’s audio-format support.
Choice A
Sennheiser, AMBEO Soundbar Mini
Sennheiser AMBEO Soundbar Mini
The AMBEO Mini keeps room calibration and Wi-Fi music in a bar under 28 inches wide. Its single HDMI TV connection is a hard limit for an optical-only TV or anyone who wants to plug sources into the bar.
- Best matched use
- Start with one soundbar and no separate subwoofer to place
Checked facts
- Supplied speaker package: One soundbar
- Main-bar width: 70 cm, about 27.56 inches
- Main-bar height: 6.9 cm, about 2.72 inches, including feet
- TV and wired audio: HDMI eARC, no optical or analog input
Choice B
Polk Audio, MagniFi Mini AX
Polk MagniFi Mini AX
The Mini AX is the smallest bar here by width, making it useful between closely spaced TV feet. The included subwoofer moves part of the system onto the floor, so the tiny bar does not mean a one-box setup.
- Best matched use
- Fit a 14.4-inch bar between closely spaced TV legs
Checked facts
- Supplied speaker package: Soundbar plus wireless subwoofer
- Main-bar width: 14.4 inches
- Main-bar height: 3.1 inches
- TV and wired audio: HDMI eARC, optical and 3.5 mm analog
Meaningful differences
What changes the fit
| What changes | Sennheiser AMBEO Soundbar Mini | Polk MagniFi Mini AX | Why it matters |
|---|---|---|---|
| Supplied speaker package | One soundbar | Soundbar plus wireless subwoofer | Polk requires a separate position and mains supply for the bass enclosure. |
| Main-bar width | 70 cm, about 27.56 inches | 14.4 inches | Polk saves about 13.16 inches of horizontal space. |
| Main-bar height | 6.9 cm, about 2.72 inches, including feet | 3.1 inches | Polk's narrower body is about 0.38 inches taller. |
| TV and wired audio | HDMI eARC, no optical or analog input | HDMI eARC, optical and 3.5 mm analog | An older TV or analog source has a documented direct route on Polk. |
| Later physical rear speakers | No supported rear addition documented | Optional Polk SR2 surrounds | Polk offers a documented expansion path behind the seating position. |
| Wi-Fi music | AirPlay 2, Chromecast and supported streaming services | AirPlay 2, Chromecast and Spotify Connect | Wi-Fi playback is shared, so it does not by itself require a separate subwoofer. |
What you give up
Every choice has a cost
If you choose Sennheiser AMBEO Soundbar Mini
- Its body is about 13.16 inches wider than Polk's.
If you choose Polk MagniFi Mini AX
- The main bar is about 0.38 inches taller despite being narrower.
Recommendation switch
The decision flips if...
The setup must stay to one supplied enclosure
Choose Sennheiser AMBEO Soundbar Mini. The reviewed AMBEO Mini offer contains one soundbar without a separate bass box.
The television only supplies optical audio
Choose Polk MagniFi Mini AX. Polk provides the required direct optical input.
A video source must connect directly to an HDMI input on the bar
Choose neither. Both offer TV audio return without a separate HDMI video-source socket.
What matters in practice
How to make the call
Count enclosures before measuring the bar
AMBEO Mini is the more straightforward package when a separate bass box has nowhere to go. Polk's narrow bar can fit furniture that AMBEO cannot, but its included subwoofer still needs floor space and mains power. Include that second location in the installation plan rather than judging the system solely by what sits beneath the television.
An older television can decide the purchase
Polk's optical input is useful when the TV lacks HDMI audio return, and its analog input covers a different class of wired source. AMBEO Mini needs the documented HDMI connection for TV audio. Confirm the actual output on the back of the television and the audio formats it passes. Neither bar adds a separate HDMI video-source input.
Plan any later speakers without promising a sound result
Polk's optional SR2 surrounds create a documented route to physical speakers behind the seating position. AMBEO Mini supplies onboard room-calibration microphones and processing for its standalone arrangement. Both support network music. The appropriate choice follows your layout and expansion plans, while the strength of the surround effects in your room remains unmeasured.
What this comparison cannot tell you
- We have not compared bass extension, dialogue intelligibility or surround effects. A supplied subwoofer does not prove better bass in every room, and neither body-width example includes the manufacturer's placement clearance.
