The catch
Sennheiser AMBEO Soundbar Mini
Direct optical and analog inputs are absent.
Side by side
Sennheiser AMBEO Soundbar Mini vs Polk MagniFi Mini AX compared: Polk has the smaller bar, yet it adds a powered floor box and more source options
Quick verdict
AMBEO Mini is the pick when you want one enclosure and have a compatible HDMI audio-return connection. MagniFi Mini AX is the pick for a much narrower main bar, an optical or analog source and a supplied subwoofer. Wi-Fi music comes with both, yet Polk's compact bar still puts a second powered box in the room.
Before you buy
Why, and what it costs you
Two different installations go by the name Mini
AMBEO Mini keeps the enclosure count down. Polk keeps the bar narrow and puts the bass hardware in a second enclosure.
Where this comes from
Both have Mini in the name, but the package layouts differ. The verified AMBEO offer contains one bar, and the Polk offer contains a bar and powered wireless subwoofer.
The catch
Polk MagniFi Mini AX
A separate location and mains power are needed for the included subwoofer.

In practice
Differences you will notice
Two different installations go by the name Mini
AMBEO Mini keeps the enclosure count down. Polk keeps the bar narrow and puts the bass hardware in a second enclosure.
How we worked this out
Both have Mini in the name, but the package layouts differ. The verified AMBEO offer contains one bar, and the Polk offer contains a bar and powered wireless subwoofer.
Only Polk’s bar fits a 20-inch opening
AMBEO Mini’s body overshoots the opening by about 7.56 inches. Polk has 5.6 inches of total width left before placement clearance.
How we worked this out
The separate Polk subwoofer is left out of this body-width calculation. 20 - 14.4 = 5.6 inches. 70 / 2.54 = 27.56 inches. 27.56 - 20 = 7.56 inches.
With an optical-only TV, the connector decides it
AMBEO Mini’s specified TV connection is HDMI eARC, whereas Polk provides a direct optical input. Similar wireless music features cannot fix that wired TV mismatch.
How we worked this out
The Sennheiser SB02 Mini input table lists HDMI TV eARC and a service USB port, with no optical or analog audio. Polk’s input table lists HDMI eARC, optical and analog 3.5 mm.
Plug in your numbers
Is there room for the soundbar under your TV?
Measure the clear space under your TV. Count only the devices you will plug into the soundbar. Leave out the ones already connected to the TV. The numbers below are placeholders until you enter yours.
Sennheiser AMBEO Soundbar Mini
Fails these checksWith 0 separate HDMI source inputs, it cannot take the 1 device you want to plug into the bar.
Polk MagniFi Mini AX
Fails these checksAt 3.1 inches tall, it is higher than the 3 inches below your picture.
Measure the top of an open shelf. This check does not cover enclosed cubbies. Detachable speakers count toward the docked width. Leave extra depth for cables and the TV stand. This checks size and port count only. Dolby Atmos, 4K/120Hz passthrough and the audio formats your TV supports are outside it.
Option A
Sennheiser, AMBEO Soundbar Mini
Sennheiser AMBEO Soundbar Mini
In a bar under 28 inches wide, the AMBEO Mini still has room calibration and Wi-Fi music. The catch is a single HDMI TV connection, which rules out an optical-only TV and anyone hoping to plug sources into the bar.

Option B
Polk Audio, MagniFi Mini AX
Polk MagniFi Mini AX
No other bar here is narrower than the Mini AX, so it can work between TV feet that sit close together. The tiny bar does not make this a one-box setup, though, because the included subwoofer puts part of the system on the floor.

Spec by spec
Where they really differ
| Spec | Sennheiser AMBEO Soundbar Mini | Polk MagniFi Mini AX | In practice |
|---|---|---|---|
| Supplied speaker package | One soundbar | Soundbar plus wireless subwoofer | A separate position and mains supply are needed for Polk’s bass enclosure. |
| Main-bar width | 70 cm, about 27.56 inches | 14.4 inches | Polk takes about 13.16 inches less horizontal space. |
| Main-bar height | 6.9 cm, about 2.72 inches, including feet | 3.1 inches | Though narrower, Polk’s 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 | Polk documents a direct route for an older TV or analog source. |
| Later physical rear speakers | No supported rear addition documented | Optional Polk SR2 surrounds | A documented expansion path behind the seating position is offered by Polk. |
| Wi-Fi music | AirPlay 2, Chromecast and supported streaming services | AirPlay 2, Chromecast and Spotify Connect | Both do Wi-Fi playback, so it alone does not call for a separate subwoofer. |

Change of plan
When the answer changes
The setup has to be limited to a single supplied enclosure
Go with Sennheiser AMBEO Soundbar Mini. One soundbar and no separate bass box is what the reviewed AMBEO Mini offer contains.
Audio from the television comes only through optical
Go with Polk MagniFi Mini AX. The required direct optical input is on Polk.
A video source has to plug straight into an HDMI input on the bar
Neither model fits. TV audio return is on both, with no separate HDMI video-source socket.
Decision guide
How to decide
AMBEO Mini suits one enclosure with a compatible HDMI audio-return connection. MagniFi Mini AX suits a much narrower main bar, an optical or analog source and a supplied subwoofer. Both offer Wi-Fi music, but the compact Polk bar still brings a second powered box into the room.
Count the boxes before you measure the bar
When a separate bass box has nowhere to go, AMBEO Mini is the more straightforward package. Polk's narrow bar can fit furniture that AMBEO cannot, but its included subwoofer still takes floor space and mains power. Put that second location in the installation plan and do not judge the system solely by what sits beneath the television.
An older TV can make the choice for you
When the TV lacks HDMI audio return, Polk's optical input helps, and its analog input serves 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 which audio formats it passes. Neither bar adds a separate HDMI video-source input.
Plan later speakers without promising how they will sound
A documented route to physical speakers behind the seating position comes from Polk's optional SR2 surrounds. For its standalone arrangement, AMBEO Mini supplies onboard room-calibration microphones and processing. Network music works on both. Your layout and expansion plans should drive the choice, because the strength of the surround effects in your room remains unmeasured.
What this page can’t tell you
- Bass extension, dialogue intelligibility and surround effects have not been compared by us. A supplied subwoofer does not prove better bass in every room, and the manufacturer's placement clearance is left out of both body-width examples.
