BlueAnt | X4 Portable Bluetooth Party Speaker 50W Bluetooth 5.0 | Splashproof Black
The BlueAnt BAX4BK is a portable 50W Bluetooth party speaker with a rechargeable battery, five LED light modes and a wired microphone included. The BAX4BK runs Bluetooth 5.0 on the A2DP profile and produces 25W RMS at 10% THD across a 75Hz to 20kHz response. It is the black X4, rated splashproof, with a moulded carry handle and a weight of 2.6kg.
A site radio takes a beating and still sounds like a site radio. Phone speakers do not carry across an open slab, and circulating a handset at smoko satisfies nobody. The 50W total output fills a shed or a backyard without being driven into audible distortion. A 133mm woofer and 51mm tweeter with a bass vent reproduce low frequencies a compact enclosure normally cannot deliver.
At 2.6kg with a moulded handle, the X4 relocates between the ute, the shed and the backyard in a single trip. The built-in power bank replenishes a phone directly from the speaker battery, valuable on a site with no permanent supply connected. Party mode links up to 100 units, so a pair of speakers covers a substantial slab from opposite ends. The DC 12V adaptor delivers continuous operation wherever a socket outlet is available.
Features
- 50W total output — rated 25W RMS at 10% THD, with a published total maximum output of 50W.
- 133mm woofer and 51mm tweeter — two-way driver arrangement with a bass vent, covering 75Hz to 20kHz.
- Bass Boost button — a single press lifts the low end without opening a menu or an app.
- Bluetooth 5.0 — the BAX4BK pairs over Bluetooth 5.0 using the A2DP profile for stereo audio streaming.
- Up to 12 hours playtime — published runtime from the 7.4V 5000mAh battery pack, before the light show is factored in.
- Five LED light modes — coloured light patterns that move in time with the music, plus an off setting.
- Party mode to 100 speakers — links and synchronises with up to 100 X4 units for larger areas.
- Built-in power bank — charges a phone from the speaker battery while the music continues playing.
- Microphone included — a wired microphone ships in the box for announcements, speeches or a karaoke turn.
- Built-in carry handle — a moulded handle on a 2.6kg body means the BAX4BK relocates by hand.
- Rapid charge DC adaptor — the supplied adaptor operates the speaker on DC 12V 2A and recharges the battery.
- Splashproof, not waterproof — BlueAnt rates the X4 as splashproof only, so submersion and heavy rain are outside its scope.
Where to use
- Site sheds and smoko rooms — the BAX4BK covers a lunch room on battery, with no power point needed nearby.
- Open slabs and framing stages — 50W carries further across an open build than a phone or a compact speaker.
- Ute and van transport — 2.6kg with a handle, so it travels in the tray and comes out at the next job.
- Backyards and barbecues — the splashproof body suits a deck or a poolside table under cover.
- Garages and workshops — battery or DC adaptor operation for a space occupied in short sessions.
- Camping and caravan trips — battery playtime plus a power bank for phones away from mains supply.
- Parties and functions — LED light modes and the included microphone for announcements and speeches.
- Multi-speaker setups — the BAX4BK synchronises with additional X4 units to cover a larger area evenly.
BlueAnt rates the X4 as splashproof rather than waterproof, so it should not be submerged or left out in heavy rain. Operating temperature is published as 5 to 40 degrees Celsius, which rules out a closed ute tray on a hot summer afternoon. This is a consumer audio product rather than a rated workplace tool, and site noise requirements still govern how loudly it runs.
