Acoustic Audio by Goldwood Bluetooth 2.1 Speaker System 2.1-Channel Home Theater Speaker System, with Optical/Aux/USB/SD Inputs Black (AA2172)

Sound and performance you can reasonably expect

The AA2172 is built as a classic 2.1 system, meaning you are getting a dedicated powered subwoofer plus two wired satellite speakers. In reviews, the most common theme is that it delivers “surprisingly good” impact for the category, with bass that can be adjusted to avoid the “boomy” feel some budget systems get. Buyers also describe the mid and high range as crisp and clear once the tone controls are dialed in.

Frequency response and tuning matter here because the subwoofer is specified to cover roughly 40 Hz up to 20 kHz, and in practice buyers talk about reducing boomy behavior by changing bass and treble settings. The best results typically come from spending a few minutes getting the levels matched to your space and listening volume.

Inputs and connectivity for TV, PC, gaming, and Bluetooth music

One of the biggest reasons people choose this system is the variety of ways to connect it. You can stream wirelessly over Bluetooth, or use wired inputs depending on what your source supports:

• Optical input for TVs and streamers with optical audio out.
• Dual RCA stereo inputs for many TVs, DVD players, and audio outputs.
• 3.5mm AUX for devices with headphone/line-out.
• USB and SD for playing local music from compatible drives.

For buyers using a computer or Chromebook, Bluetooth pairing is commonly described as easy. For TV setups, RCA connections are often the quickest path, and the inclusion of multiple cables in the box makes it more likely you can start without hunting for adapters.

Controls, remote, and day-to-day usability

The AA2172 includes both onboard controls (on the subwoofer) and a remote that handles volume, bass/treble adjustments, and input switching. Review feedback suggests the remote is helpful, but it may require more intentional aiming than some users expect. If you plan to tuck the subwoofer behind a TV console, keep remote line-of-sight in mind.

There is also a notable control tradeoff for buyers who want independent bass levels. One review reports the bass level behavior changes with volume adjustments (while treble remains constant), so you may prefer to set bass first and then avoid frequent bass changes at different volume levels.

Setup and placement tips that affect results

With a powered subwoofer, placement can strongly influence how tight or boomy the bass feels. One review mentions the subwoofer’s port is on the right side, which is a useful detail when placing it near walls or shelving. If your listening area has limited airflow around the sub, you may need to reposition slightly and then re-tune bass and treble.

Also, because the system uses wired satellite speakers, plan basic cable routing so the speakers end up where you want them in your room.

Pros and cons summary

• Best for: people who want a budget-friendly 2.1 home theater-style speaker system for TV and desktop audio, who value flexible connectivity (Bluetooth, optical, RCA, AUX, plus USB/SD).
• Works well when: you’re willing to tune bass and treble to your room and you place the subwoofer with reasonable spacing.
• Who should avoid: buyers who need perfectly independent bass control at every volume level, or who expect long-range, “point it once and forget it” remote behavior.

Verdict: is the AA2172 worth it?

The Acoustic Audio by Goldwood AA2172 is a strong value pick if your priority is getting fuller, subwoofer-style bass without stepping up to a pricier surround system. The feature set (optical, RCA, AUX, Bluetooth, USB, SD) makes it a practical “one system for many sources” choice. If you are picky about how bass behaves when you adjust volume, or you want a remote that works perfectly from any angle, consider whether you can live with the reported control and aiming quirks.
