Compact Powered Pair for Desktop Use

The Onkyo GX-30ARC-BLK is a set of two active bookshelf speakers finished in black. Each unit houses a 4-inch woofer and a 3/4-inch tweeter driven by dual Class D amplifiers with DSP. The pair delivers a maximum output of 115dB and covers a frequency response of 55Hz to 20kHz, making it suited for near-field listening at a desk, console or shelf.

Connectivity Options Shape Daily Workflow

One speaker provides HDMI ARC with CEC, optical, RCA, 3.5mm jack and USB-C inputs plus Bluetooth, so a TV, computer, phone or turntable can connect without an external receiver. Bass-reflex tuning extends low-end presence despite the small cabinet. The built-in amplification removes the need for a separate amp, freeing surface space and reducing cable count.

Simple Placement With One Cable Catch

Only the primary speaker requires mains power; a single speaker cable links the secondary unit. HDMI ARC setup depends on the TV supporting CEC handshake, which some older sets lack. Optical and analogue inputs avoid that dependency. The rear-panel layout keeps connectors accessible when speakers sit close to a wall, though the USB-C port carries audio only, not device charging.

Questions about this item

Will the 4" woofer or 3/4" tweeter need replacement after long use?

The drivers are built into the powered enclosure and are not user-serviceable; if a driver fails the speaker would need professional repair.

What limits output first during a long session — the 115 dB max SPL or thermal protection?

The 115 dB maximum output is the hard ceiling; the Class D amps with DSP will engage protection before thermal limits are reached.

How much heat or fan noise appears when the pair runs all day over HDMI-ARC?

Class D amplification runs cool with no fan, so the cabinets stay near room temperature and add no audible noise during extended use.
