Audison AV1-1 1.1" Voce Series Tweeters (Pair)

The Audison AV 1.1 is a pair of 28 mm (1.1-inch) component tweeters designed to add dedicated high-frequency reproduction to a car audio system. They are suited to replacing factory tweeters or building a custom active or passive component front stage. With a 4-ohm nominal impedance and 92 dB sensitivity, they can be matched with compatible car-audio amplification and crossover hardware.

These tweeters are intended for listeners who want a separate high-frequency driver rather than relying on a coaxial speaker’s integrated tweeter. Their specified 1.2 kHz to 22 kHz frequency response supports detailed upper-frequency reproduction when the drivers are properly high-pass filtered. The compact 48 mm outer diameter also helps with installations in factory sail panels, dash locations, or custom A-pillar pods where space permits.

The AV 1.1 uses a Tetolon dome, a silk-and-cotton material with proprietary damping treatment. Audison pairs this dome with a lightweight, double-layer CCAW copper-clad aluminum voice coil to keep the moving assembly compact. The design is intended to provide efficient, controlled high-frequency output with a natural level of detail.

An annular rear damping chamber and dedicated damping material are part of the AV 1.1’s acoustic design. This rear-chamber construction is engineered to extend usable low-frequency response for a tweeter and reduce harmonic distortion. A high-flux-density neodymium magnet supports the compact motor assembly.

The AV 1.1 can be used with compatible Audison Voce woofers, midrange drivers, passive crossovers, or an active DSP-based system. Audison specifies high-pass filtering at 2.0 kHz with a 12 dB/octave slope for the tweeter’s 180-watt peak power-handling specification. Proper crossover selection, polarity, aiming, and level matching are important for integrating the tweeters into a balanced system.

Key Features

• 28 mm Tetolon Dome: Silk-and-cotton dome material supports smooth high-frequency reproduction.
• Neodymium Magnet: High-flux motor design keeps the tweeter assembly compact.
• Double-Layer CCAW Voice Coil: Lightweight copper-clad aluminum construction promotes efficient operation.
• Annular Rear Chamber: Damped rear volume supports lower tweeter crossover capability.
• 4-Ohm Nominal Impedance: Designed for use with compatible car-audio amplifiers and crossovers.
• Compact Mounting Profile: 48 mm outer diameter and 15.2 mm mounting depth.

Design & Installation

The AV 1.1 combines a 28 mm Tetolon dome with a 28 mm double-layer CCAW voice coil on a Kapton former. Its neodymium motor measures 27.9 mm, while the annular rear damping chamber uses dedicated damping material. Each tweeter weighs 0.073 kg and has a total depth of 28 mm.

Confirm available mounting space before installation: the specified mounting diameter is 44.8 mm, outer diameter is 48 mm, and mounting depth is 15.2 mm. Use a suitable high-pass crossover or DSP setting; Audison specifies a 2.0 kHz high-pass filter at 12 dB/octave for the listed peak-power condition. The pair is supplied with grilles, and installation should be planned around correct left/right aiming, secure mounting, and matching the tweeter level to the accompanying midbass or midrange drivers.
