Polk MagniFi Max AX SR vs Samsung HW-Q990F: Polk adds a third HDMI input, Samsung confirms 4K120 and saves subwoofer space

The short answer

Choose Max AX SR for three HDMI inputs and a narrower central bar. Q990F suits 4K 120Hz sources and saves substantial floor space with its subwoofer.

Before you choose

The reasoning and the trade-offs

Check the real width under the TV

MagniFi Max AX SR measures 45 inches across the central bar, compared with 48.5 inches for HW-Q990F/ZA. The gap is 3.5 inches before any docked rear speakers.

What this is based on

Absolute cabinet width difference = |45 - 48.5|. Allow additional space for cables, TV legs and acoustic clearance. A detached central bar measurement does not include removable rear speakers.

Main trade-off

Polk MagniFi Max AX SR

Polk gives one more direct source connection

Winner by situation

Start with what you need it to do

  • Connect three HDMI source devices

    Three HDMI inputs can accommodate more players than Samsung two. The documented Polk passthrough ceiling is 4K 60Hz, which matters for a high-refresh console or PC.

  • Pass 4K 120Hz through the soundbar

    Q990F documents 4K 120Hz passthrough. Its compact square subwoofer also uses far less cabinet floor area than the Polk subwoofer.

What matters in practice

The differences that matter

Check the real width under the TV

MagniFi Max AX SR measures 45 inches across the central bar, compared with 48.5 inches for HW-Q990F/ZA. The gap is 3.5 inches before any docked rear speakers.

How we reached this conclusion

Absolute cabinet width difference = |45 - 48.5|. Allow additional space for cables, TV legs and acoustic clearance. A detached central bar measurement does not include removable rear speakers.

Count the source connections before adding a switch

MagniFi Max AX SR accepts 3 direct HDMI sources, while HW-Q990F/ZA accepts 2. Other players need suitable TV inputs or a separately chosen switch.

How we reached this conclusion

Count HDMI source inputs only, excluding the HDMI output/eARC TV connection. Inputs recorded: 3 and 2. TV passthrough and supported video modes still need checking.

Samsung cuts the subwoofer cabinet footprint by about 49%

Q990F uses about 96 square inches against Polk at 187, before ventilation and cable space.

How we reached this conclusion

9.8 × 9.8 = 96.04 square inches. 11.9 × 15.7 = 186.83. (1 - 96.04 / 186.83) × 100 = 48.6%.

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 Max AX SR

Needs a manual check

A cabinet dimension or the selected connection is not confirmed for this exact model.

Samsung HW-Q990F

Does not meet these checks

It needs 48.5 inches of width, more than your 48 inches.

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.

Polk MagniFi Max AX SR

The Max AX SR suits a movie setup with several HDMI sources and space for powered rear speakers. It bundles the 10-inch subwoofer and both rears, but its 4K 60 Hz passthrough is a limit for high-refresh consoles.
