One Audio - Reconceptualising Extreme 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.

IB2 Series - Finesse And Kinetics Collide
You’re on the horns of a dilemma. You’re the consummate distinguished lady or gentleman, desiring the very best subsonic performance from your speakers and subwoofers. However you also possess a dark side; that mean streak within you that sends a rush of blood to the head from time to time causing you to crank the volume to such a point you struggle to see straight. That’s going to take one special range of components to blend such accuracy with copious amounts of volume. Welcome to the IB2 range. Developed by Scott Atwell in the US of A; these super drivers not only provide delightful quality and control but can kick like an angry stallion when required.

Design Ideologies
The superb IB2 range from One Audio forms the entry point to the company’s infinite-baffle / open-baffle subwoofer range. However closer inspection reveals a driver engineered around considerably more than basic low-frequency reproduction.

Magnificent Motor
The motor incorporates a two-layer, 2″ / 50.8 mm copper voice coil together with a full-length copper pole sleeve, with both elements employed to reduce and linearise inductance. This inductance management helps maintain a more consistent electrical load through the driver’s operating range, extending usable bandwidth while reducing distortion and improving transient accuracy. With a mechanically rated 250 Watts at 20 Hz and 22 mm of Xmax; the IB2 also possesses substantial linear excursion capability for reproducing the lowest octaves with authority.

Masterful Mechanical Architecture
The mechanical architecture is similarly focused on linearity. A rigid fiber-impregnated, non-pressed curvilinear paper-pulp cone provides the required stiffness-to-mass characteristics. While the specially formulated foam surround and Kevlar spider are engineered to maintain controlled, symmetrical suspension behaviour throughout the driver’s excursion range.

Marvelous Magnetics
The triple-stacked magnet assembly increases mechanical clearance around the motor and suspension components, while the IB2’s relatively high Qts is particularly appropriate to infinite-baffle and open-baffle alignments. Rather than relying on a conventional enclosure to provide acoustic loading, the driver’s electrical and mechanical parameters are configured to work effectively in applications where the front and rear radiation are separated by the vehicle’s structure or installation baffle.

Vertical Alignment
One Audio also manufactures the IB2 with a vertically integrated approach, machining the steel components and assembling the completed subwoofers in-house. This allows the company to maintain tighter control over the critical mechanical interfaces and assembly tolerances that ultimately influence driver consistency. Taken as a complete system the IB2 combines high excursion, copper-based inductance mitigation, a substantial motor assembly and a carefully controlled suspension with the high-Qts characteristics required for IB/OB loading. The result is an entry-level driver whose engineering emphasis is firmly on low-frequency linearity, bandwidth, transient behaviour and resolution rather than simply maximum output.
