"A compact, punchy 18-inch active sub that delivers surprising SPL and clean low-end for small- to mid-size PA rigs."
Review of ANT Greenhead 18S
I ran the ANT Greenhead 18S through rehearsals and a few small club sets to see how an 18-inch active sub from a value-oriented brand would behave in real-world PA use - my goal was simple, reliable low-end that pairs easily with two full-range tops. From the first mixdown I heard a tight low-bass character and enough output to push a room without feeling bloated or overworked, which is exactly the kind of sub I was hoping to find for compact systems and mobile DJs who need impact without a huge footprint.
First Impressions
Out of the case the Greenhead 18S feels solid for the price - the 18 mm plywood cabinet is well finished with a hard-wearing black covering, and the full grille plus beefy side handles give the impression of something built to be moved around. The weight is noticeable but manageable at about 33.2 kg - heavy enough to feel substantial, light enough for a single person to load into a van with care. Hookup is straightforward - combo XLR/TRS on the left/mono input, XLR right input, and balanced Xover link outs to feed two tops directly, which simplifies rigging when you want to run one sub and two tops without extra processing.
Design & Features
The Greenhead 18S is built around an 18-inch custom ferrite woofer with a 2.5 inch voice coil and an onboard Class-D amplifier quoted at 1600 W peak - a specification that translates to usable headroom in small venues. On the control panel you get a volume knob plus useful switches - ground lift, low-cut and phase - and the sub offers balanced Xover outputs so it can feed two full-range cabinets with a filtered crossover signal, which is handy for quick PA setups. The top has an M20 pole thread so you can mount a top on a pole or stack tops on the sub, and the full metal grille protects the driver when the box is moved or stacked.
Build Quality & Protection
The plywood cabinet and scratch-resistant finish stood up to several load-ins without marking, and the handles are bolted in solidly - I felt confident stacking and moving the box without worrying about rattles or loose hardware. The grille is robust and the driver sits deep enough to avoid accidental contact when positioning on stage, and the M20 pole mount is a convenience I used every time I had to pole a top above the sub. Overall, it feels like a practical, workmanlike build rather than a luxury finish - which is exactly what I would want for a road-friendly PA sub.
Comfort & Portability
At 33.2 kg the Greenhead 18S is not light, but the handles and relatively compact footprint - 661 x 535 x 560 mm - make it straightforward to move for a single operator who is used to handling heavy speakers. I appreciated that the box is compact enough to stack and fit in smaller vans, and the top recess/pole mount design reduces the number of separate accessories I need to carry. For one-person setups I still recommend a ramp or assistance for repeated load-ins, but for gig-to-gig use it's a reasonable compromise between driver size and portability.
Real-World Experience
In rehearsal and small club gigs the Greenhead 18S delivered a tight, relatively fast low end - kick drums and low synths had presence without the excess boom that can muddy mixes in smaller rooms. Running a single 18S with two 15-inch full-range tops gave me enough authority down low for dance-oriented sets up to a few hundred people if levels were managed; on larger, open-air gigs it was clear more sub is needed, but that is true of most single-sub setups. I did notice a faint intermittent mechanical/buzz after extended continuous use on one of my test sessions that cleared after power-cycling the unit - it was not loud enough to ruin a set but worth noting and something I monitored during subsequent use.
The Trade-Offs
There are compromises - the low-frequency extension is specified to around 42 Hz (-10 dB), so if you need sub-20 Hz extension for very large clubs or organ-type content this is not the sub for you. The onboard controls are functional but basic - there is no parametric EQ or advanced DSP navigation, so you trade processing flexibility for simplicity and lower cost. Finally, while output is impressive for the cabinet size - ANT quote up to 129 dB SPL - heat management and long-term high-SPL operation require sensible gain staging to avoid stressing the amp on prolonged full-power gigs.
Final Verdict
The ANT Greenhead 18S is a pragmatic, cost-conscious active sub that gives a lot of usable low-end and SPL for its size, with straightforward connections and the practical features you need for quick PA setups - pole mount, balanced Xover outs and simple phase/low-cut switches. I recommend it for mobile DJs, rehearsal spaces and small to mid-size venues where you want punchy bass without a lot of extra processing or a heavy case budget - it performs well when used within its intended scope, but if you need deep subsonic extension or advanced onboard DSP you should look at higher-tier alternatives.
by Musicngear Verified Community ReviewsHelpful Tips & Answers
- What is the weight and will I need help loading it into a van?
- The unit is about 33.2 kg and has solid side handles - I could move it short distances solo but I recommend a helper or a ramp for repeated load-ins to avoid strain.
- Does it have a pole mount for tops?
- Yes - there is an M20 pole thread on top and I used it frequently to pole a full-range speaker for compact PA setups.
- What connectors are available for hooking up tops?
- It has combo XLR/TRS on the left/mono input, XLR right input, and balanced XLR link outs to feed two tops directly - very straightforward in practice.
- How low does it go - will it cover sub-bass for electronic music?
- The specified response is around 42 Hz to 130 Hz (-10 dB) - it delivers punchy bass for electronic music in small-to-medium venues but it won't reach the deepest subsonic extension some larger systems provide.
- Is the output loud enough for club gigs?
- ANT quotes up to 129 dB SPL peak - in my club tests a single unit paired with two tops delivered convincing impact for rooms up to a few hundred people when used with sensible gain staging.
- Any reliability or noise concerns to watch for?
- During extended sessions I noticed a faint intermittent buzz on one unit that cleared with a power cycle - I recommend checking units before a gig and monitoring during long runs.

"Compact, punchy 15" active sub that delivers surprising SPL and clean low-end for small-to-medium PA systems."
Review of ANT Greenhead 15S
I spend a lot of time putting compact PA systems together for rehearsal rooms, small gigs, and weekend DJ sets, so I was curious to see whether the ANT Greenhead 15S - a 15" active subwoofer with a relatively small footprint - could replace bulkier subs in everyday setups. My use case was straightforward - pair a single sub with two full-range tops and see how it behaved across live music, DJ playback, and spoken-word PA duties.
First Impressions
The cabinet arrived looking purposeful - a black, scratch-resistant finish over a sturdy plywood build with clean edges and integrated side handles that make it easy to maneuver solo. I immediately noticed the top-mounted M20 pole cup and the full grille design, which made stacking a single top on the sub feel secure and compact for transport to small venues.
Out of the box the controls are minimal but sensible - a volume knob, ground-lift, low-cut and a phase switch - which matches the no-nonsense design philosophy of a gig-focused sub. My first soundcheck showed solid sub-extension and surprising headroom for the size - it felt louder than I expected at modest settings, and the low-end was tight rather than boomy.
Design & Features
The Greenhead 15S is voiced as a vented 15" active sub with a Class D amplifier rated to 1200 W peak and a 15" ferrite woofer with a 2.5" voice coil - the spec sheet lists a frequency range that reaches down to around 42 Hz (-10 dB) and a maximum SPL in the 125-126 dB region, which explains the authoritative feel I got in small rooms. The cabinet is built from 18 mm plywood, weighs about 25.3 kg, and measures roughly 580 x 455 x 511 mm - compact enough to fit into a modest car with careful packing.
I/O is straightforward and pro-friendly - left/mono XLR plus 1/4" jack inputs, a right XLR input, and XLR link outs for left/right, plus XLR line outs. Onboard controls are limited to level, phase, low-cut and a ground lift - there is no fancy DSP or onboard parametric EQ, but the built-in stereo Xover output simplifies creating a compact PA with two tops without an external crossover. These choices keep the user experience simple and focused on quick setup for live sound work.
Build Quality & Protection
The plywood cabinet feels robust and roadworthy for regular gigging - the finish resists scuffs and the grille is full-face which helps protect the woofer. Handles are molded into the sides in a way that makes lifting less awkward than some other compact subs, and the M20 pole cup is solidly mounted for supporting a single full-range cabinet above.
I did notice that fitting protective corners or a cover helps if you intend to toss this in the back of a van with other gear - the cabinet is durable, but the painted finish can show marks under heavy handling over time.
Portability & Setup
At around 25 kg the Greenhead 15S is heavy enough to feel substantial but light enough for one person to move short distances, which I appreciated when carrying gear between club rooms and rehearsal spaces. The top pole mount makes building a full PA quick - one person can stack and wire a system fast, and the lack of an external crossover simplified setup in live scenarios where time is limited.
Because there is no onboard DSP routing beyond the fixed crossover outputs, you either accept the sub/top balance with the onboard attenuation or use a small mixer/processor to fine tune - in practice I found I could get a useful balance fast by using the top’s own level controls and the sub's low-cut switch for vocal or music-focused gigs.
Sound & Real-World Experience
I used the sub with a pair of compact 12" and 15" tops across different gigs - acoustic trio rehearsal, electronic DJ set, and a small bar show with a singer. In all these situations the low-end felt controlled and tight - kick drums had impact without flab, and basslines had presence without overwhelming the mids. The sub’s 42 Hz -10 dB spec means it does not extend like an 18" box, but it provides very usable punch and a sense of weight for audiences up to a couple of hundred people when paired with efficient tops.
One surprise was the level of SPL you can get from a single unit - the Greenhead 15S reaches useful levels before feeling strained, and the phase switch is effective at helping align the sub with nearby tops for cleaner summation. For spoken word and DJ playback the sub added warmth without clouding voices, and for bands it gave a clear envelope to the low end without smearing transient detail.
The Trade-Offs
This is not a replacement for a full-sized 18" powered sub if you need subterranean, chest-rattling LF below 35 Hz - it’s a 15" sub with a focus on punch and clarity rather than ultimate extension. Also, if you want detailed tone-shaping and FIR/linear-phase alignment tools you will need an external DSP since onboard controls are intentionally simple.
Lastly, while the build is solid, heavy-duty touring crews might prefer ruggedized flight-roof corners and more recessed handles - the Greenhead feels gig-ready but not overbuilt to the extreme of dedicated tour subs.
Final Verdict
The ANT Greenhead 15S is a compact, no-frills active subwoofer that impressed me with its clean, punchy low-end and surprising SPL for a single 15" enclosure. It is best suited to musicians, small-venue PA operators, and mobile DJs who need a dependable sub that is easy to integrate and quick to set up - and who do not require the deepest sub-bass extension or onboard DSP features.
If you want a compact, well-built sub that keeps the low end tight and controlled without complex setup and at a reasonable price point, the Greenhead 15S is a very sensible option - just bring a small processor or use your mixer if you need fine-grained EQ and alignment control.
by Musicngear Verified Community ReviewsHelpful Tips & Answers
- How low does the Greenhead 15S go - will it handle deep electronic bass?
- It reaches down to about 42 Hz (-10 dB) so it provides strong punch and presence, but it won’t reproduce the deepest sub-bass like a dedicated 18" sub; for club-style subsonics you may want an 18" partner.
- Can one Greenhead 15S power a full PA for a 100-person venue?
- Yes - paired with two efficient full-range tops one Greenhead 15S gave me more-than-adequate low-end and SPL for rooms of roughly 50-150 people depending on music style and room acoustics.
- Does it have onboard DSP or EQ for alignment?
- No, the unit relies on simple controls - level, phase, and a low-cut switch - so I used a small external processor when I needed precise alignment or EQ shaping.
- Is it easy to move around for a single person?
- Yes, at about 25 kg it is manageable for one person for short moves and the side handles help, though it is still heavy enough that I used a second person for loading into vehicles.
- What connectors are available for linking to tops?
- The Greenhead 15S has left/mono XLR plus 1/4" jack inputs, a right XLR input, and XLR link/line outputs which make it straightforward to hook up and send crossover outputs to left/right tops.
- Is the cabinet roadworthy for frequent gigging?
- In my experience it’s robust for regular club and rehearsal use - plywood construction and a full grille offer good protection, though heavy-duty flight cases are recommended for frequent touring.
