HK Audio Sonar 115 Sub D: German Bass Power for Aussie Stages
HK Audio Sonar 115 Sub D: German Bass Power for Aussie Stages

Looking for a subwoofer that'll shake the room without breaking your back? The HK Audio Sonar 115 Sub D might just be what you've been hunting for. German engineering in a surprisingly portable package. And honestly? It punches way harder than you'd expect from a 15-inch cab.
But here's the thing – there's heaps of powered subs on the market right now. So what makes this one worth your hard-earned dollars? Let me break it down.
What Makes the Sonar 115 Sub D Different?
HK Audio's been building pro sound gear since 1979. They're not mucking around. The Sonar series sits in their mid-tier range, designed for working musicians, mobile DJs, and smaller venues that need proper bass without the price tag of their premium Linear series.
This 15-inch powered sub delivers around 1000W of amplification. That's proper headroom for most pub gigs, corporate events, and club installations across Australia. The Class D amp keeps things efficient too – less heat, less weight, more power.

Key Features That Actually Matter
Let's cut through the marketing fluff. Here's what you're really getting:
- 15-inch neodymium woofer – lighter than traditional ferrite, punchy response
- Integrated DSP – crossover, limiting, and phase alignment sorted for you
- Pole mount socket – stick your tops directly on for easy setup
- XLR thru outputs – daisy chain to more subs or send signal to tops
- Rugged birch plywood cab – proper construction, not cheap MDF
- Recessed handles – your roadies will thank you
What I reckon sets it apart? The DSP integration. So many powered subs in this price range give you raw power but leave the tuning to you. HK's done the hard work. Plug in, set your level, done.
Sound Quality – Does It Actually Deliver?
Short answer: yeah, it bloody does.
The frequency response typically extends down to around 40Hz, which covers pretty much everything you'd need for live music and DJ work. You're not getting infrasonic rumble like an 18-inch sub, but that's not the point. The 115 Sub D gives you tight, musical bass that supports without overwhelming.
For reference – most kick drums live around 50-80Hz. Bass guitars fundamental around 40-100Hz. This sub handles all of it comfortably. EDM producers wanting that subsonic club feel might want to look at something bigger, but for everything else? Sorted.
Who Should Buy This Sub?
Perfect for:
- Cover bands playing pubs and clubs (150-400 capacity venues)
- Mobile DJs doing weddings and corporate gigs
- Houses of worship needing clean, controlled bass
- Small venues wanting permanent installation
- Audio hire companies building versatile rental stock
Maybe not ideal for:
- Large outdoor festivals (you'd want multiple units or bigger subs)
- Bass-heavy EDM events wanting below 35Hz
- Ultra-budget setups (there are cheaper options, just not as good)
How Does It Compare?
Against the QSC KS112 or EV ELX200-18SP? The HK sits nicely in between. You're getting German engineering quality at a sensible price point. Not quite premium, definitely not budget. That sweet spot where professional meets practical.
The build quality feels noticeably more substantial than similarly-priced competitors. And that DSP tuning? Makes a real difference when you're setting up quickly at different venues.

Buying in Australia: What You Need to Know
Shipping professional audio gear in Oz can be a nightmare. These units aren't light (around 30-35kg typically), so freight costs add up fast. MusiconStage offers competitive shipping to Sydney, Melbourne, Brisbane, Perth and everywhere in between.
You're also getting proper Australian warranty support – not dealing with overseas distributors when something goes wrong. That matters more than most people realise until they actually need warranty service.
FAQ: Quick Answers
Can I use it with other brand tops?
Absolutely. The XLR outputs and adjustable crossover mean you can pair it with pretty much any powered tops. EV, QSC, Yamaha – whatever you've got.
How many do I need?
One handles most pub gigs. Pair them for larger venues or outdoor work. For serious bass-heavy stuff, run two in stereo or mono stacked.
Is the pole mount sturdy?
Yeah, it's a proper 35mm socket. Standard industry fitting. Holds your tops securely.

Look, the HK Audio Sonar 115 Sub D isn't trying to be everything to everyone. It's a well-built, properly tuned 15-inch powered sub that delivers reliable low-end for working musicians and sound techs. German engineering, sensible price, solid performance.
If you're gigging regularly, doing mobile DJ work, or kitting out a small venue – this is a ripper choice. Heaps of power, quality construction, and that HK Audio pedigree backing it up.
