As a mobile DJ, your gear needs to be flexible, utterly reliable, and, crucially, easy to transport and set up. For months, I&rsquo;ve been gigging with JBL Professional speakers, and they&rsquo;ve genuinely surprised me. The JBL EON ONE Mk2 has become my go-to wedding workhorse; it&rsquo;s powerful, versatile and built for the road. Its sibling, the EON ONE Compact, adds incredible mobility and versatility for smaller gigs or as a vital backup. Together, they form a seamless DJ rig, handling everything from intimate ceremonies to lively receptions with professional polish and the freedom of battery power.
This isn&rsquo;t just about cutting a power cord; it&rsquo;s about redefining what a mobile DJ can achieve. Battery-powered PA systems have truly come of age, offering uncompromised audio quality that rivals, and often surpasses, traditional mains-powered systems from just a few years ago.
First impressions &amp; build quality: Robustness meets practical portability
The moment you see the EON ONE Mk2, JBL&rsquo;s commitment to pro-grade portability is obvious. It&rsquo;s an intelligently designed, self-contained column array system. The main enclosure, housing the 10-inch woofer and electronics, is crafted from rugged polypropylene &ndash; chosen for its durability and relatively light weight. At around 19.3kg (42.5lb), it&rsquo;s light enough to lift comfortably with one hand, a huge bonus during speedy load-ins and load-outs, especially in challenging venues.
This design ensures quicker setup and more efficient movement between spaces. For even easier transport, the optional JBL EON ONE Mk2 Transporter dolly system is a revelation, allowing you to effortlessly roll your entire PA system, saving your back and precious time.
Performance: Sound that fills any room
The Mk2 doesn&rsquo;t just look good, it sounds incredible. Powered by a robust 1,500-watt peak (400W RMS) Class D amplifier, its acoustic package consists of a C-shaped array of eight 2-inch tweeters paired with a powerful 10-inch woofer. This combination delivers crisp, full-range sound across an impressive frequency range from 37Hz to 20kHz. This means deep, satisfying bass you can feel, coupled with sparkling, articulate highs, ensuring vocals and musical details are crystal clear. With a maximum SPL (Sound Pressure Level) of 123 dB when on AC power (and a still very potent 119 dB on batteries), 
The Mk2 is surprisingly loud for a battery-powered system. This gives it ample headroom to fill typical wedding reception spaces (up to 150-200 guests) with vibrant sound, without ever sounding strained.
The 140&deg; horizontal coverage from the C-shaped array is a true blessing at weddings. It ensures incredibly even sound dispersion across dance floors and seated areas, eliminating those dreaded &lsquo;hotspots&rsquo; or &lsquo;dead zones&rsquo;. Everyone, regardless of where they are in the room, gets a consistent and enjoyable audio experience, creating a more cohesive atmosphere.
Mixer and processing: Your digital command centre
Built directly into the subwoofer cabinet is a professional-grade 5-channel digital mixer. It offers both intuitive physical controls &ndash; like three rotary EQ knobs for quick adjustments &ndash; and deep digital customisation. The Mk2 integrates a full suite of Lexicon effects (reverb, chorus, delay) for adding professional polish. Crucially for live performance, it features dbx DriveRack Inside technology, which includes Automatic Feedback Suppression (AFS) to intelligently eliminate feedback before it becomes an issue. Soundcraft Easy Ducking is another invaluable feature, automatically lowering background music when a microphone signal is present, ensuring speeches and announcements are heard clearly.
What truly elevates the mixer is the JBL Pro Connect app. This allows for complete remote control of every parameter from your phone or tablet. You can tweak channel EQs, adjust effects, fine-tune AFS, and save/recall custom presets from anywhere in the venue. 
Imagine adjusting vocal levels for a speaker walking away from the stage, or adding more reverb to a singer, all from the palm of your hand. This level of remote control streamlines your workflow and ensures optimal sound in real-time.
Battery convenience: Powering your freedom
The integrated, sealed lithium-ion battery is the heart of the EON ONE Mk2&rsquo;s mobility. JBL advertises around six hours of continuous playtime at maximum output, and from my extensive use, this figure holds true in real-world scenarios. This is phenomenal for a full-power PA. The Variable Power Performance feature intelligently optimises output to maximise battery life, ensuring you get the most out of every charge.
For exceptionally long events, the swappable battery unit is a stroke of genius. 
You can simply carry a charged spare and pop it in mid-gig, providing crucial peace of mind and saving you from unexpected power woes. A full charge takes approximately 2.5 to three hours. This level of battery performance means you can confidently DJ entire ceremonies, lengthy cocktail hours, or even smaller full receptions in locations where traditional power is unavailable or unreliable.
Connectivity: Plug-and-play professionalism
The Mk2 offers robust connectivity. You get three versatile combo XLR/TRS jacks, allowing phantom power on two channels for condenser microphones, along with line-level inputs. There&rsquo;s also a dedicated hi-Z &frac14;"input for instruments, 
and a summed 3.5 mm/AUX input for quick connections from media players.
The integrated Bluetooth 5.0 is vital not just for streaming audio, but also for the stable, extended range control via the JBL Pro Connect app. Furthermore, the Mk2 supports a Bluetooth audio + control link that allows you to daisy-chain up to 10 units. This is incredibly powerful, enabling you to scale your sound system across multiple zones in a large venue, ensuring even sound distribution all controlled wirelessly from one device. There&rsquo;s also a balanced &frac14;&rdquo; passthrough output for analogue system expansion.
Suitability for weddings: The ultimate flexible solution
The Mk2 is a true chameleon, ideal for virtually every segment of a wedding day. Its sound quality excels at vocal clarity for speeches and singing, while the powerful woofer holds its own through upbeat dance sets. While dedicated subwoofers might be desired for earth-shaking bass in very large venues for extreme genres, for weddings up to 150-200 guests, it more than delivers a fantastic full-range experience.
 I&rsquo;ve personally used it for outdoor ceremonies far from power outlets, for discreet cocktail hour music, for amplifying speeches, and as the main PA for evening receptions. Its versatility is unmatched.
JBL EON ONE Compact &ndash; the little workhorse
While the Mk2 is the powerhouse, its smaller sibling, the EON ONE Compact, is no less impressive for its role. It&rsquo;s the perfect companion, or a formidable standalone unit for smaller tasks.
Design and portability: Ultra-compact and ready for anything.The EON ONE Compact genuinely lives up to its name. Significantly lighter at just 8kg (17.6 lbs), it slips effortlessly into car boots, backseats, or even a tight corner on a stage. Its moulded enclosure feels just as tough as its larger counterpart, yet it&rsquo;s incredibly easy to handle. A thoughtful addition is the integrated tablet holder, perfect for script reading or app control. The &lsquo;polarity-aware controls&rsquo; are ingenious, automatically adjusting the&nbsp; EQ to suit potition - whether the unit is stood upright or laid down as a wedge monitor, ensuring optimal sound quality.
Sound quality: Surprising punch from a small package
Inside, the Compact houses an 8" woofer and a 1" tweeter combo, delivering up to 112 dB SPL. While it won&rsquo;t rival the Mk2&rsquo;s sheer output, it offers surprisingly full sound for its size, reaching down to 37.5 Hz. This means it provides genuinely musical bass, not just a tinny sound. It&rsquo;s ideal for smaller wedding moments, such as intimate ceremonies, background music during cocktail hours, or as a crisp, clear monitor for a performer or DJ. Its 100&deg; x 60&deg; dispersion is perfect for targeted coverage.
Mixer and features: Channels and connectivity
Its built-in 4-channel digital mixer is incredibly versatile. It includes two combo mic/line channels (with phantom power on CH1 for condenser mics), a dedicated hi-Z instrument channel, and a Bluetooth/AUX channel. 
Like the Mk2, it offers an 8-band EQ, Lexicon effects (reverb, chorus, delay), and one-touch ducking. Two high-power USB ports (5V/2A and 5V/1A) are invaluable for charging phones or devices mid-gig.
Battery performance: Enduring power
The EON ONE Compact truly excels in battery life, with a swappable battery that delivers up to 12 hours per full charge at moderate volumes, or about six hours at max output. This makes it a full-day event solution, perfect for extended background music, multiple remote ceremony locations, or continuous monitor use. Its quick-charge capability means it can be fully replenished in just 2.5 hours when not in use.
Whether you&rsquo;re managing vows under an oak tree or firing up the dance floor in a banquet hall, the JBL EON ONE Mk2 and EON ONE Compact make a fantastic mobile DJ combo. The Mk2 delivers serious punch, pro-grade features, and battery-powered freedom for larger wedding moments and main receptions. Meanwhile, the Compact perfectly handles smaller setups, provides crystal-clear audio for ceremonies in remote locations, serves as a discreet cocktail hour system, or acts as an indispensable personal monitor.
Together, they offer unparalleled flexibility, unwavering reliability, and consistently polished sound that every modern wedding DJ can depend on. This is also reflected in JBL's 7-year warranty. Investing in this JBL ecosystem means investing in the ability to deliver exceptional audio, anywhere, anytime, with minimal fuss and maximum impact.
