Listening to Dolby Atmos

The MagniFi Mini AX doesn’t have vertically firing audio system for Dolby Atmos or DTS:X peak channel results so the overhead sound and 3D immersive sound stage is created just about. 

Polk incorporates SDA know-how which did present a wider soundstage and audio peak that goes past the bodily borders of the MagniFi Mini AX soundbar, however you don’t get the identical Dolby Atmos expertise as you’ll with setups that embody ceiling-mounted audio system. I discovered that listening to Dolby Atmos on the MagniFi Mini AX was pretty lackluster in comparison with what I’m used to. 

Some Audio Setting Shortcomings

The MagniFi Mini AX has a grasp quantity management and separate bass degree management for the subwoofer, however there isn’t a separate peak channel degree management. This would have made the Mini AX extra adaptable to ceiling peak and maybe enhance the immersive sound results. 

Tip: There are encompass degree and steadiness controls when utilizing the Mini AX with the non-compulsory encompass audio system (extra on that under).


The connections supplied with the MagniFi Mini AX embody:

Final Thoughts

The predominant takeaway in utilizing the Polk Audio MagnaFi Mini AX is that it supplies a much bigger sound expertise than you’ll count on from its small dimension. Voice readability is superb (supported nicely by the Voice Adjust function), and there’s a good steadiness between the soundbar and subwoofer. 

The MagniFi Mini AX positively boosts the TV viewing expertise as a result of it’s higher than most built-in TV speaker methods.

However, though the Mini AX supplies a fuller soundfield than you’ll count on from its small type issue, there isn’t a getting round that regardless of the inclusion of Dolby Atmos/DTS:X and SDA audio processing, the soundbar is simply bodily too small to mission convincing immersive peak and broad encompass results in a big room. In my opinion, the MagnaFi Mini AX is best suited to use in a smaller room (comparable to a studio condo or bed room) and with a smaller display screen TV. 

For music, Bluetooth, Apple AirPlay, and Chromecast Built-in are additionally included (as talked about beforehand). Pairing is simple and casting is secure. The MagniFi Mini AX produces clear vocals and satisfactory element for music listening albeit with a reasonably slim soundstage in comparison with a conventional stereo speaker setup. 

Also, in case your PC soundcard has a digital optical or 3.5mm stereo audio output, the MagniFi Mini AX would additionally make an excellent PC soundbar – and simply place the subwoofer on the aspect or beneath your desk (the place your toes received’t kick it).
