One Audio - Reinventing Audio
When it comes to car audio equipment there are enthusiasts, there are audiophiles and then there's Mr Scott Atwell. His passion for audio was kindled nearly forty years ago, thenceforth resulting in the creation of his company One Audio. Hailing from the USA, One Audio is a company focused purely on aural passion and hence synonymous with top-notch build quality and indelible technical expertise. Put succinctly, there's little Scott doesn't know when it comes to the art of producing audiophile grade audio equipment. Starting from humble beginnings designing products for use within his own home and car, during his tenure people quickly noticed just how good the products from this astute little company were. Today the company remains modestly sized despite its products being in extremely high demand. Ergo if you want to up your game with some serious calibre audio equipment; One Audio is one company that ought to be top of your short list.

IBn3 Series - The Amalgamation Of Accuracy And Realism
Not everyone boasting a high-end subwoofer wants to bother the entire neighbourhood with it. On the contrary there's an echelon of discerning audiophiles who desire supreme sound quality above all else, caring little for entertaining those outside the vehicle. They seek elements like articulated infrasonics, linear subsonics and tightly controlled lower midbass registers from their subwoofer. Entertaining others isn't an interest, and budgets are of a lesser concern. This is the territory of the delightful IBn3 range from One Audio. Developed by Scott Atwell in the USA with every detail scrutinised to perfection; the IBn3 drivers are capable of aural achievements until now though nigh-on impossible.

Design Ideologies
The latest evolution of the IBn3 range represents a classic One Audio subwoofer design, complete with all the lavishes of modern technological and metallurgical revisions. Every aspect of the IBn3 subwoofers were tailored towards being as detailed and articulate as possible while still handling excellent power for increased bottom octave output.

Uncompromising Subsonics
Welcome to a new world of stellar subsonics. Experience uncompromising bass performance with One Audio state-of-the-art infinite baffle subwoofer, designed specifically for car audiophiles and home theater purists. Engineered for seamless integration into infinite baffle arrangements, the IBn3 series subwoofers deliver ultra-clean, articulate low-frequency response with exceptional control. The low-induction motor structure ensures minimal distortion, preserving the purity and detail of every note—even at high output levels. This results in tight, accurate bass that enhances your audio system without the boomy resonance common in traditional subwoofers. Whether you’re building a reference-level listening room or upgrading your mobile pride and joy; the IBn3 subwoofers are the ultimate low-frequency solution.

The Motor Within
At the heart of the powerhouse IBn3 drivers are four black high grade neodymium magnets, firmly mounted to a billet 6061-T6 alloy mounting frame. These magnets serve to provide superbly dense magnetic strength in a compact, lightweight design. Situated in the centre of this is a thermally efficient former wrapped in a high-conductivity voice coil. Multiple aluminum rings are also installed to reduce and linearise inductance. This advanced motor system provides high efficiency and fast transient response, ensuring deep lows that are both powerful and musical.

Framing It All
Surrounding the magnet stacks are a multitude of thick, custom profiled carbon legs; firmly attached at multiple levels for a lightweight yet extremely rigid structure. Utilising carbon fibre instead of traditional alloy allows One Audio to keep the subwoofers overall weight down. This design also offers superior thermal dynamics, providing an optimised cooling system and guaranteeing long-term reliability and consistent performance under demanding conditions.

Advanced Diaphragm
Exciting the air molecules is a light weight Rohacell core carbon cone, held concentric thanks to a soft and linear surround. The result is a very strong but light cone with exception damping and Young’s modulus figure. This allows for perfect pistonic movement that’s both nimble and fluid.
