Main trade-off
Polk MagniFi Mini AX
A separate subwoofer still needs floor space and electrical power.
Head-to-head
Polk MagniFi Mini AX vs Sonos Beam Gen 2: Polk saves stand width but needs a floor subwoofer and more screen height
The short answer
Choose MagniFi Mini AX if the gap between TV feet is the main problem and there is room for its subwoofer. Choose Beam Gen 2 if you want the whole starting system on the TV stand with no separate bass box. Polk is far narrower but taller, so measure both directions.
Before you choose
The reasoning and the trade-offs
Polk is about 43.8% narrower across the stand
The width saving is 11.23 inches compared with Beam.
What this is based on
The calculation is (25.63 − 14.4) ÷ 25.63. That helps with closely spaced TV feet, but it says nothing about the space needed by the included subwoofer.
Main trade-off
Sonos Beam (Gen 2)
No separate HDMI source inputs and no Bluetooth music playback.

- Choose it for
- You do not have floor space for a subwoofer.

What matters in practice
The differences that matter
Polk is about 43.8% narrower across the stand
The width saving is 11.23 inches compared with Beam.
How we reached this conclusion
The calculation is (25.63 − 14.4) ÷ 25.63. That helps with closely spaced TV feet, but it says nothing about the space needed by the included subwoofer.
The narrowest bar can still block a low screen
Mini AX is 3.1 inches tall, compared with 2.68 inches for Beam.
How we reached this conclusion
With a 2.9-inch screen gap, Beam meets the cabinet-height constraint while Polk does not. Raising the TV may be necessary even when the tiny Polk bar easily fits across the stand.
Polk moves about 112 square inches of cabinet footprint to the floor
Its subwoofer is 7.2 inches wide and 15.6 inches deep.
How we reached this conclusion
The base is 112.32 square inches before clearance. Beam’s standard package avoids a separate bass cabinet but does not include the same external component.
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.
Polk MagniFi Mini AX
Does not meet these checksIts 3.1-inch height exceeds the 3 inches below your picture.
Sonos Beam (Gen 2)
Does not meet these checks0 separate HDMI source inputs cannot take the 1 device you want to connect to the bar.
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
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
- Closely spaced TV feet when there is room for a separate subwoofer
Checked facts
- Bar measures 14.4 × 3.1 × 4.1 inches.
- Subwoofer cabinet measures 7.2 × 14.6 × 15.6 inches.
- One HDMI eARC TV connection, optical input and a 3.5 mm analog input.
- VoiceAdjust, Night Mode and Wi-Fi music streaming are supported.
- Compatible SR2 rear speakers are sold separately.
Choice B
Sonos, Beam Gen 2
Sonos Beam (Gen 2)
The Beam fits a narrow TV stand and keeps a path open to a larger Sonos system. Its Atmos presentation uses processing rather than upward-firing drivers, and room tuning needs a compatible iPhone or iPad.
- Best matched use
- A compact TV setup with optional rear speakers later
Checked facts
- Cabinet measures 25.63 × 2.68 × 3.94 inches.
- HDMI eARC or ARC connection and an included optical adapter.
- Five amplified drivers, with no upward-firing drivers.
- Wi-Fi music, AirPlay 2, Night Sound and Speech Enhancement are supported.
