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 Bose Smart Soundbar: Polk saves width but needs a second power location and more screen clearance
The short answer
Choose the Polk MagniFi Mini AX if the opening between your TV's feet is narrow and there is room for a separate subwoofer. Choose the 2024 Bose Smart Soundbar for one low bar with no floor box. Polk saves counter width, but it is taller and needs a second power location.
Before you choose
The reasoning and the trade-offs
Polk saves 47% of the bar width
That helps a narrow TV stand, but does not make the whole package a one-box system.
What this is based on
(27.34 - 14.4) / 27.34 × 100 = 47.3%. Calculation compares bars only. Polk also supplies a separate subwoofer.
Main trade-off
Bose Smart Soundbar
No ADAPTiQ room calibration.

What matters in practice
The differences that matter
Polk saves 47% of the bar width
That helps a narrow TV stand, but does not make the whole package a one-box system.
How we reached this conclusion
(27.34 - 14.4) / 27.34 × 100 = 47.3%. Calculation compares bars only. Polk also supplies a separate subwoofer.
Some of Polk's footprint moves to the floor
Its subwoofer occupies a 112.3-square-inch rectangle before cables and placement clearance.
How we reached this conclusion
Subwoofer base: 7.2 in × 15.6 in = 112.32 square inches. This is separate from the 14.4 × 4.1-inch bar and is not an acoustic placement recommendation.
A 20-inch-wide, 2.5-inch-high opening fits neither
Polk passes width but fails height. Bose passes height but fails width.
How we reached this conclusion
Example requires width <=20 in and height <=2.5 in. Polk is 14.4 × 3.1 in. Bose is 27.34 × 2.21 in. One model must satisfy both measurements.
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.
Bose Smart Soundbar
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
Bose, 892079-1100 (2024)
Bose Smart Soundbar
The 2024 Smart Soundbar combines a cabinet under 28 inches wide with upward-firing speakers and Wi-Fi music. It is easier to place than the Smart Ultra, although it leaves out the Ultra room-calibration system.
- Best matched use
- A small, low TV stand with real upward-firing speakers
Checked facts
- Cabinet measures 27.34 × 2.21 × 4.09 inches.
- Five speaker units include two upward-firing speakers.
- HDMI eARC and optical TV connections.
- Wi-Fi music, Bluetooth and dialogue enhancement are supported.
- This listing is the 2024 Smart Soundbar, not the older Smart Soundbar 600.
Meaningful differences
What changes the fit
| What changes | Polk MagniFi Mini AX | Bose Smart Soundbar | Why it matters |
|---|---|---|---|
| Bar width | 14.4 in | 27.34 in | Polk needs much less width. |
| Bar height | 3.1 in | 2.21 in | The narrower Polk can still obstruct a low picture. |
| Bar depth | 4.1 in | 4.09 in | Depth is effectively tied. |
| Subwoofer supplied | Yes | No | Polk needs floor space and another power outlet. |
| Upward-firing drivers | None | Two | This describes the height-effect method, not a listening-test winner. |
| Separate HDMI source inputs | None | None | Neither adds a console connection. |
| TV connections | eARC, optical and 3.5 mm analog | eARC and optical | Polk also accepts an analog source. |
| Rear expansion | Optional Polk SR2 | Optional compatible Bose surrounds | Each uses its own compatible accessories. |
What you give up
Every choice has a cost
If you choose Polk MagniFi Mini AX
- There are no separate HDMI source inputs.
If you choose Bose Smart Soundbar
- No separate HDMI source inputs.
What matters in practice
How to make the call
Attach the word small to a location
Polk is small on the stand. Bose is low and keeps the initial setup in one enclosure. Decide where the shortage is. A subwoofer with nowhere sensible to go is not a free improvement.
Wireless still needs power
The Polk subwoofer receives audio wirelessly but still plugs into an outlet. Count available powered locations before choosing the package. Bose's optional bass module would add the same kind of placement question later.
Keep driver counts in perspective
Bose has physical upward-firing drivers while Polk uses virtual height processing. Neither specification tells us how convincing the effect will be under your ceiling. Placement and listening position still matter.
What this comparison cannot tell you
- No listening test or measured bass-output comparison is claimed.
- Cabinet dimensions exclude operating and cable clearance.
