Rockville’s ONE-TOWER BG is a wired tower speaker that delivers big sound for home use, but it requires a wall outlet at all times. That makes it a stationary system rather than a portable one, despite the “Bluetooth speaker” label. The trade-off is real power: dual 4-inch woofers and a rear port tuned to 35Hz push bass down to 32Hz, which is unusual for a single-box unit under $100. Two more 4-inch polypropylene drivers handle mids and highs with clarity that holds up at high volume.

Bluetooth 5.0 gives you a 33-foot range and stable streaming from any phone or tablet. The USB port supports playback from drives up to 32GB, which is handy for parties or playlists you don’t want to stream. There is also HDMI, optical, and RCA input options, so you can connect a TV, game console, or turntable directly. Peak power is rated at 20 watts, which is modest, but the cabinet design and port tuning make it sound louder than the number suggests.

The MDF construction feels solid, and the plug-mount setup is simple. Just keep in mind this is not a grab-and-go speaker. It stays put. If you need something for a living room or garage that can get loud without distortion, the ONE-TOWER BG delivers. Just don’t expect to take it to the park.
