Onkyo GX-AiO 100 – Mid-size 2.1 for living rooms

The GX-AiO 100 sits in the middle of the Onkyo Creator GX-AiO range: a wider cabinet than the 50, with the same true 2.1 layout of two main drivers and a dedicated, independently amplified subwoofer built into the enclosure. It is the version most living rooms want, big enough to fill the space on its own and still small enough to live on a sideboard.

Key Features

• True 2.1 architecture: Dual main drivers plus a dedicated, independently amplified subwoofer.
• Integrated bass enclosure: The bass-reflex duct runs through the illuminated rear slit.
• Class D with DSP: Full-digital amplification keeps noise, distortion and heat low.
• Three power modes: Eco, Standard and Max reshape the output range around the room.
• One hub for everything: HDMI ARC, USB-C, optical, Bluetooth 5.3 and a switchable line/phono input.
• True Wireless Stereo: Pair two units and they split into dedicated left and right channels.

Customer Benefits

A living room asks a speaker to do several jobs in one evening. HDMI ARC puts the TV on the same volume knob, the switchable phono input takes a turntable without a separate stage, and Bluetooth 5.3 covers everything a guest wants to play. The step up in cabinet size over the GX-AiO 50 is where the extra headroom lives, so Standard Mode is enough for most nights and Max is there when the room fills up. Add a second unit and the pair separates into left and right for a wider image.

Pros and Cons

✅ Pros:

• Middle of the range, so it covers most rooms without oversizing
• Dedicated powered subwoofer inside a single cabinet
• Television, turntable and laptop all connect directly
• Vertical or horizontal placement with a grille designed for each

⚠️ Cons:

• Bluetooth only for wireless streaming, with no Wi-Fi or network playback
• Large open-plan spaces will be better served by the GX-AiO 150

The GX-AiO 100 is the one to pick when a room needs to be filled properly but a component system is more than you want to own.
