Subwoofers with minimal mounting depth requirements continue to grow in popularity. To meet that demand, the team at Audison has introduced a larger, more robust option to complement their well-regarded Prima Series. The new Voce II subwoofer line includes ten- and twelve-inch models engineered for higher power handling and increased excursion. In this spotlight, we’ll take a closer look at the 12-inch Audison AV 12 D2 II.
Features of the Voce II Subwoofers
As its name suggests, the AV 12 D2 II is a 12-inch subwoofer. It requires only 3.46 inches of mounting depth, making it an excellent solution for trucks or vehicles where space is at a premium.
The D2 suffix identifies its dual two-ohm voice coil configuration. A dual four-ohm version, designated D4, is also available. Ten-inch Voce II models share the same design principles and construction quality.
Audison rates the AV 12 D2 II at 550 watts continuous and 1100 watts peak power handling. This capability comes from a 1.5-inch six-layer copper-clad aluminum wire voice coil. To help keep the motor assembly cool during extended use, the basket and motor structure incorporate Audison’s Airflow Venting Cooling (A.V.C.) architecture.
The woofer is built on a custom-tooled, cast-aluminum eight-spoke frame. Instead of the traditional vent through the center of the T-yoke, the AV 12 D2 II uses four large vents in the bottom plate below the spider. Combined with the air gaps between the magnet and chassis, these openings form part of the A.V.C. system.
The cone and dust-cap support assembly is a one-piece injection-molded polypropylene structure. The dust-cap face piece is bonded and supported around its perimeter just above the fiberglass voice coil former. This design minimizes unwanted flexing or resonance. Audison refers to this reinforcement method as Radial Reinforced Frameworks (R.R.F.).
A single ferrite magnet serves as the motor structure. The six-layer voice coil is connected via tinsel leads, internally supported by the R.R.F. and externally by large spring-loaded terminals mounted to the chassis. These terminals can accept up to 8-AWG speaker wire for maximum current transfer and include labels for which of the two coils they are connected to. There are wire management tabs built into the terminals as well.
Specifications of the Audison AV 12 D2 II
Digging into performance parameters, the AV 12 D2 II features a resonant frequency (Fs) of 23 Hz, an equivalent compliance (Vas) of 2.225 cubic feet, and a Total Q (Qts) of 0.5. Cone excursion is rated at 16.8 mm, voice coil inductance is 4.3 millihenries, and sensitivity is 85 dB SPL.
We modeled the driver in BassBox Pro using Audison’s recommended 0.957 cubic foot sealed enclosure. The simulation shows an impressive -3 dB point of 38.4 hertz with a system Q (Qtc) of 0.812. The software also predicts solid cone control down to single-digit frequencies at the rated 550-watt continuous input.
