Polk MagniFi Mini AX vs Sonos Beam Gen 2: Polk narrows the footprint on the stand, yet needs a floor subwoofer and more screen height

Quick verdict

MagniFi Mini AX is the pick when the gap between the TV feet is your main problem and there is room for its subwoofer. Beam Gen 2 is the pick when you want the whole starting system on the TV stand, with no separate bass box. Polk is far narrower but taller, so measure in both directions.

Before you buy

Why, and what it costs you

Across the stand, Polk is about 43.8% narrower

Against Beam, Polk is 11.23 inches narrower.

Where this comes from

It is (25.63 − 14.4) ÷ 25.63. That helps if the TV feet are close together, but it tells you nothing about the space the included subwoofer needs.

The catch

Polk MagniFi Mini AX

The separate subwoofer still takes up floor space and needs power.

The catch

Sonos Beam (Gen 2)

It has neither separate HDMI source inputs nor Bluetooth music playback.

In practice

Differences you will notice

Across the stand, Polk is about 43.8% narrower

Against Beam, Polk is 11.23 inches narrower.

How we worked this out

It is (25.63 − 14.4) ÷ 25.63. That helps if the TV feet are close together, but it tells you nothing about the space the included subwoofer needs.

A bar this narrow can still block a low screen

Beam stands 2.68 inches tall and Mini AX stands 3.1 inches.

How we worked this out

Given a 2.9-inch screen gap, Beam satisfies the cabinet-height constraint and Polk fails it. You might have to raise the TV even though the tiny Polk bar fits across the stand with ease.

About 112 square inches of Polk’s cabinet footprint ends up on the floor

The subwoofer measures 7.2 inches across and 15.6 inches deep.

How we worked this out

Before clearance, the base is 112.32 square inches. Beam’s standard package has no separate bass cabinet and does not include the same external component.

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.

Polk MagniFi Mini AX

Fails these checks

At 3.1 inches tall, it is higher than the 3 inches below your picture.

Sonos Beam (Gen 2)

Fails these checks

With 0 separate HDMI source inputs, it cannot take the 1 device you want to plug into the bar.

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.

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.

Best for
TV feet set close together, with room for a separate subwoofer

Facts we checked

  • The bar is 14.4 × 3.1 × 4.1 inches.
  • The subwoofer cabinet is 7.2 × 14.6 × 15.6 inches.
  • A 3.5 mm analog input, an optical input and one HDMI eARC TV connection.
  • Support covers VoiceAdjust, Night Mode and Wi-Fi music streaming.
  • Compatible SR2 rear speakers are a separate purchase.
Option B
Sonos Beam (Gen 2)

Sonos, Beam Gen 2

Sonos Beam (Gen 2)

A narrow TV stand is no problem for the Beam, and it leaves the door open to a larger Sonos system. Its Atmos effect comes from processing. It has no upward-firing drivers. Room tuning also requires a compatible iPhone or iPad.

Best for
A small TV setup where rear speakers may come later

Facts we checked

  • The cabinet is 25.63 × 2.68 × 3.94 inches.
  • An included optical adapter comes with the HDMI eARC or ARC connection.
  • Five amplified drivers, none of them upward-firing.
  • Support covers Wi-Fi music, AirPlay 2, Night Sound and Speech Enhancement.

Decision guide

How to decide

01

Across the stand, Polk is about 43.8% narrower

Next to Beam, Polk saves 11.23 inches of width. The calculation is (25.63 − 14.4) ÷ 25.63. Closely spaced TV feet benefit from that, but the figure tells you nothing about the space the included subwoofer needs.

02

A bar this narrow can still block a low screen

Beam stands 2.68 inches tall and Mini AX stands 3.1 inches. Given a 2.9-inch screen gap, Beam satisfies the cabinet-height constraint and Polk does not. You may have to raise the TV even though the tiny Polk bar fits easily across the stand.

03

About 112 square inches of Polk’s cabinet footprint ends up on the floor

The Polk subwoofer measures 7.2 inches wide by 15.6 inches deep, so its base is 112.32 square inches before clearance. Beam’s standard package has no separate bass cabinet, and it does not include that same external component.

Check these before you buy

  • Measure the feet and the screen gap on your own TV.
  • Put the Polk subwoofer on your floor plan.
  • If you connect over optical, check that it delivers the formats you expect, minus Atmos.

What this page can’t tell you

  • This comparison rests on manufacturer specifications and package contents rather than a controlled listening test. How a bar sounds also depends on room shape, placement and source content.
