Acoustic Audio AA5172
Score: 71/100
Polk Monitor XT70 Midnight Black
Score: 79/100Rankings
The Polk Monitor XT70 is a floor-standing tower speaker delivering detailed highs and deep bass with dual passive radiators, making it ideal for hi-res and Dolby Atmos setups. Its large size and lack of a built-in subwoofer may be drawbacks in smaller rooms. Best suited for medium-large home-theater spaces.
The Acoustic Audio AA5172 delivers 700 W of 5.1-channel power with a range of wired and Bluetooth inputs, making it a solid budget home-theater solution. However, it lacks independent verification and is geared toward wired setups, limiting flexibility. Best suited for users who already have a receiver and want an affordable, feature-rich system.

Professional reviewers consistently commend the XT70 for its linear on-axis response, low harmonic distortion, and the combination of a Hi-Res dome tweeter with dual passive radiators that deliver detailed highs and deep, clean bass. They also note its versatility across 4 Ω and 8 Ω amplifiers and its suitability for high-resolution audio and Dolby Atmos/DTS:X setups, while cautioning about sensitivity variance and the need for a capable amplifier.
Everyday users praise the XT70 for creating immersive, lifelike sound in movies, games and music, especially noting the strong bass and crystal-clear highs that work well with streaming services. The main themes of satisfaction revolve around easy integration with existing AVRs and the ability to fill medium-large rooms without a separate subwoofer, while the only recurring concern is the speaker's large footprint in smaller spaces.
