MILLE Pro 10" 1000W 4 OHM SVC Subwoofer

Hertz Mille Pro 10": Saddlebag Bass with Serious Punch

Big bass. Minimal space. The Hertz Mille Pro 10" 1000W 4 OHM SVC Subwoofer (MPS250S4) is purpose-built for tight installations—like slipping seamlessly into your Harley-Davidson saddlebags. With an ultra-shallow depth of just 82.6 mm (3.25"), it's made for riders chasing hard-hitting low-end without giving up valuable gear room or clean styling.

Designed for sealed, compact enclosures. This Mille PRO sub thrives in boxes as small as 14 litres (0.49 cu ft), making it a perfect match for custom saddlebag subwoofer kits. Whether you're rolling solo or rolling deep with your crew, it adds the deep rumble your bike’s factory setup never could deliver.

20% more excursion = deeper lows on the open road. Unlike traditional shallow subs, the MPS250S4 features a smart internal suspension that boosts cone movement by 20%. That means more air, more feel, and more presence—even when you're doing 110 down the coast with your pipes wide open.

Built to handle heat, vibration and volume. From six-layer copper voice coils to Hertz’s exclusive Air Intercooling Revolution (A.I.R.) tech, this sub is engineered for real-world riding conditions. Add in the rugged die-cast aluminium frame, sealed back design, and a sleek screwless grille—and it’s ready for anything the road throws at it.

Slick install. Killer performance. Compact. Clean. Custom-ready. Whether you're upgrading your bagger’s full system or just adding low-end muscle to your tourer, the Mille Pro 10" makes every ride sound that much better.
