Acoustic Audio AA2170 2.1 Bluetooth Home Audio Speaker

2.1 Bluetooth speaker system

The Acoustic Audio AA2170 is a 2.1-channel multimedia speaker system built around a powered subwoofer and two passive wired satellites. It connects wirelessly through Bluetooth 2.1 and also accepts 3.5 mm, RCA and optical inputs for televisions, phones, laptops and consoles. A full-function remote and illuminated front panel give direct control over volume and source selection.

350-watt integrated amplifier

The single specification that decides suitability is the 350-watt total system power delivered by the built-in amplifier. This rating determines how loud and clean the system can play in a typical living-room or desktop setting. If the listening space is larger or higher output is required, the fixed amplifier cannot be upgraded or bypassed.

40 Hz low-frequency reach

The subwoofer extends down to 40 Hz, providing audible bass weight for movies, music and gaming. Two satellite speakers on 15-foot cables handle mid and high frequencies, creating a front soundstage suited to small and medium rooms. In larger rooms or for listeners who want cinema-level sub-bass pressure below 40 Hz, the system runs out of low-frequency headroom.
