Zeroflex FLX-10S — The Slim Demon of Bass

Are you ready to re-define what “slimline” means in the car audio world? Introducing the Zeroflex FLX-10S — a 10-inch subwoofer that laughs in the face of depth constraints and still slams hard.

Just 35 mm total depth
Massive 5.5-inch voice coil 
4ohm SVC

Why the FLX-10S Is a Game Changer

Unmatched Discreet Fitment: With only 35 mm of depth, this sub can hide in panels, behind side trim, under rear decks—spaces where no “conventional” 10-inch would even dream of fitting.

Power behind the slimness: That 5.5-inch coil gives you headroom, strength, and clarity that many “thin” subs with puny coils simply can’t match.

Heat management & longevity: The size advantage won’t come at the cost of durability — Zeroflex engineering ensures it handles thermal stress with dignity.

NZ/Aussie bragging rights: We scoured the Kiwi and Aussie markets — nothing out there comes close to 35 mm depth with that power in a 10-inch footprint. The closest slim subs (e.g. Alpine SWR-T10 at 82 mm depth in NZ) are still more than twice as thick.

Competitive Check: Is There Anything This Slim in NZ / Australia?

Alpine SWR-T10 — even their “thin” class sub is 82 mm deep, far more than the FLX-10S. 

Most local “slimline 10 Inch” subs are 60-90 mm+ in depth, meaning none of them touch 35 mm territory without sacrificing performance.

If you spot a thinner 10” sub in NZ/AUS with similar specs, we’d eat our slogan T-shirts — but we haven’t found one yet.

So yes — you can confidently position the FLX-10S as the thinnest, real-world, power-capable 10” sub in New Zealand and Australia.
