Subwoofer Boxes
Built to Spec, Not Guesswork
A subwoofer is only as good as the enclosure it sits in. The wrong box will kill performance, cause distortion, and stress the driver. We build every enclosure to the manufacturer's Thiele-Small parameters.
Enclosure Types
Sealed Enclosures
Tight, accurate bass with excellent transient response. Best for HiFi builds and vehicles where boot space is limited. The sub works harder but sounds tighter and more controlled.
Best for: HiFi builds, daily drivers, smaller vehiclesPorted / Vented Enclosures
Extended bass output and greater efficiency at the tuning frequency. More output per watt than sealed. Port must be tuned to the specific subwoofer's parameters for best results.
Best for: SPL builds, loud daily drivers, boot installsCustom Boot-Fit Boxes
Enclosures shaped to fit your specific vehicle's boot space — maximising usable room while keeping the sub in the right volume and alignment. Clean, OEM-looking result.
Best for: SUVs, 4x4s, sedans with limited boot spaceBandpass Enclosures
The sub fires into a ported chamber which acts as a bandpass filter. Very loud at the tuned frequency — used for competition and very loud daily setups.
Best for: Competition builds, maximum SPLWhy the Box Matters as Much as the Sub
✓Wrong volume = wrong performance
Too large and the sub becomes loose and uncontrolled. Too small and it runs out of excursion early. We build to spec every time.
✓Port tuning matters
A ported box needs the port length and diameter tuned to the sub's resonant frequency. We calculate this correctly — not guess.
✓Quality materials
18mm MDF, properly braced, sealed with silicone. No flimsy flat-pack boxes. Built to last and perform in Queensland heat.
✓Matched to your install
Every box is designed around your vehicle's boot dimensions so it fits properly and looks like it belongs there.
