We’ve said dozens of times that speakers are by a long way the most important part of any audio system, be it for a home or car. The team at Audison in Italy went to great lengths to create a truly carte blanche set of speaker solutions when they developed the Voce II series of speakers. Sharing design concepts from the premier Thesis line, Voce II speaker solutions deliver value and excellent performance for music lovers. Let’s check them out!

AV 1.1 II Tweeters

Let’s look at the AV 1.1 II tweeters first. Designed with a 1.1-inch Tetolon fiber soft dome, these are among the very few tweeters that offer good upper-midrange performance while delivering high-frequency extension to 40 kHz. They have a resonant frequency under 900 Hz, making them an ideal partner for the three-inch AV 3.0 II mids or the 6.5-inch AV 6.5 P II woofers. They can be filtered at 1.8 kHz with a fourth-order active filter.

Another key feature of the AV 1.1 II tweeters is the Any Install Faceplate (A.I.F.) installation parts included in the kit. The A.I.F. component gives your installer several choices for grilles or OE-style mounting rings available to simplify and add elegance to any installation.

AV 3.0 II Midrange

The 3.5-inch AV 3.0 II midrange speakers have been designed to offer excellent clarity, detail and output from a relatively shallow design. In fact, it’s almost 20% shallower than the driver it replaces. The speakers use a rubber surround for reliability. The cone is semi-pressed paper that offers an excellent balance of strength, rigidity and damping.

At the heart of the driver is a large 26mm glass fiber voice coil to help dissipate heat. This contributes significantly to the 50-watt continuous and 100-watt peak power rating. Crucially, Audison implemented a copper shorting ring in the motor assembly to reduce inductance and improve upper midrange output. These midrange speakers have a 3.2-ohm impedance that balances efficiency and sound quality from your chosen amplifier. The AV 3.0 II speakers have a resonant frequency of 150 hertz, allowing your installer to cross them over low enough to create a stable soundstage across the vehicle.

AV 6.5 P II Woofers

The AV 6.5 P II Woofers can serve as dedicated midbass speakers with the AV 3.0 II midrange, or as midwoofers when paired with the AV 1.1 II tweeters in a two-way system. The woofers are based on a cast-aluminum chassis and use semi-pressed pulp paper cones with an IIR rubber surround. An aluminum shorting ring in the motor assembly reduces inductance and improves upper midrange performance. The woofers feature a 40mm voice coil, which helps them handle 150 watts of power.

The AV 6.5 II and the AV 3.0 II component drivers include both the classic Faston spade terminals and a set of OEM-style automotive connectors with pigtails to make electrical connections.

AVX 6.5 II Coaxial Speakers

Audison has combined the Voce II woofer and tweeter technologies into a single point-source coaxial called the AVX 6.5 II. This 6.5-inch driver features the same semi-pressed paper cone and IIR rubber surround concepts as the dedicated woofer. In the center of the driver is a 25 millimeter Tetolon-dome tweeter. The driver components can be actively filtered with a crossover point at 3 kHz. The kit includes four passive crossover modules, two for the tweeters and two for the woofers. The tweeter crossover includes a 0 or -1.5 dB attenuation switch, and the woofer filter networks offer a selectable mid contour control.

Component Sets

Audison offers three component sets in the Voce II line. The AVK 6 P II and the AVK 6A P II include the 1.1-inch tweeters and 6.5-inch woofers. The A designation in the latter kit denotes that passive crossovers are not included as the system is intended for active filtering with a DSP-equipped amplifier.

There is another component set called the AVK 6 S II, which features a shallower 6.5-inch woofer, a 1-inch tweeter, and a passive crossover network. Power handling is reduced to 125 watts on this kit because the woofer has a smaller (but still relatively large) 36 mm voice-coil diameter.

One of the best upgrades you can make to your car audio system is to add a high-quality subwoofer. Whether you are working with a simple factory-installed radio and speaker system or planning a studio-quality listening environment, accurately reproducing bass frequencies is important. The folks at Audison have a full line of compact subwoofer enclosures that can transform your system from good to awesome. In this spotlight, we will look at the Audison APBX 10 AS2.

Features of the Audison APBX 10 AS2

The APBX 10 AS2 is a low-profile 10-inch active subwoofer enclosure. The term “active” means this unit has an integrated amplifier. Essentially, with some wiring to feed it power and a signal from the radio, this is all you need to add bass to your car, truck, or SUV.

The enclosure measures 17.3 inches long, 13.2 inches wide, and stands a mere 6.2 inches tall. The amplifier is mounted on one of the thin side panels, and the subwoofer is designed to fire down into the floor or back wall of your car or truck. Feet are included to raise the enclosure off the floor so the subwoofer doesn’t hit anything. The enclosure has rounded corners for a little extra style.

The amplifier included with the APBX 10 AS2 is rated to provide up to 400 watts of power. Audison uses a 0.16-ohm low-impedance driver in the enclosure, so the amp doesn’t need a switching power supply. This design is said to boost system efficiency.

Amplifier and Integration Features

The amplifier can accept speaker-level or preamp signals to ensure integration with factory-installed and aftermarket source units is simple and reliable. In high-level mode, the amp will accept up to 8 Vrms on the speaker leads. In low-level mode, the maximum input is 4 Vrms.

The amp has a three-position remote turn-on function switch. The amp can be activated when 12 Volts is applied to the remote terminal. Alternatively, in DC mode, the amp’s circuitry will monitor the speaker wires for the DC offset voltage from a BTL amplifier. Finally, if neither of those options works with your source unit, the amp can detect an electrical audio signal to bring things to life.

In terms of signal processing, the amp has a crossover that can be adjusted from 50 to 300 hertz and features a second-order Butterworth alignment. The internal crossover can be defeated with the Lo-Pass/By-Pass switch if you have a source unit or signal processor with integrated filtering. There is also a bass boost function that lets your installer dial in a bump of up to 6 dB at 45 Hz to add a little extra thump to your music. Finally, there’s a fixed fourth-order (-24 dB/Octave) infrasonic filter set to 24 Hz.

Audison includes their HRC AP remote level control with the APBX 10 AS2. This remote connects to the amp via the included 3.5mm jack. Your installer can mount the control on the dashboard or in the center console to give you control over the bass level. While the original gain setting should provide a nice balance, sometimes we want a little more or a little less bass, depending on our mood or the choice of music.

The amplifier includes a feature called Dynamic Bass Tracking (DBT). This circuitry monitors the audio input in real time to prevent signals that could cause distortion, keeping your music from sounding bad. This circuit will also prevent damage to the woofer.

Audison Subwoofer Features

The subwoofer integrated into the enclosure is based on Audison’s APS 10 series of drivers. The subwoofer features a heavy-gauge stamped-steel chassis to which a single ferrite magnet is affixed. Cooling vents in the basket, under the spider mounting plateau, help to keep the voice coil assembly cool. There are also vents in the cone to allow hot air to escape from the motor assembly.

The cone is made of pressed paper with a water-repellent coating to prevent it from absorbing moisture in humid or damp climates. A polypropylene dust cap keeps debris out of the magnetic gap and gives the driver’s face a clean, classy appearance.

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.

Long considered one of the forerunners in digital signal processing in the car audio industry, Audison continues their performance and technological evolution with the introduction of the new Bit One HD Virtuoso. This advanced processor builds on the success of the Bit One HD and includes upgraded premium audio components for improved sound quality, along with state-of-the-art signal routing and processing capabilities to cope with even the most-advanced and challenging of factory-installed source units and amplifiers.

Virtuoso Digital Signal Processor Basic Features

The new Virtuoso digital signal processor (DSP) includes six RCA inputs, 12 high-level inputs, a pair of RCA auxiliary inputs and two TOSLINK optical inputs. The high-level inputs are equipped with Audison’s Universal Speaker Simulator (USS), so factory-installed source units that use load-sensing to check for speakers will function normally.

The digital inputs will accept standard stereo audio data streams up to 24-bit depth and 96kHz sampling rates. There are 13 RCA preamp outputs, each rated to produce up to 4 volts of signal. Two sets of AD Link/AC Link connections are available to feed digital signals to Audison amplifiers like the Voce Series when equipped with the AV Bit IN HD digital input board. Using the AD Link/AC Link system eliminates the chance of picking up noise between a processor and an amplifier using analog connections.

Remote Volume Auxiliary Input

An interesting and unique feature of the Virtuoso is the Remote Volume Aux (RVA) feature, which lets you use the volume control on your source unit to control the output level of the processor when using its auxiliary input. The function can be enabled using a test tone stored on a USB memory stick or by connecting the RVA output to the aux input on the head unit. The Virtuoso monitors the level of the test tone and adjusts the output of the processor to match. This configuration maintains an appropriate level for Bluetooth, navigation prompts and warning chimes.

Premium Components for Superb Sound

Audison has included a variety of audiophile-grade components in the new Virtuoso processor. First, the output operational amplifiers are Texas Instruments OPAx134 SoundPlus units. These devices have a stunning 0.00008% distortion spec and add almost no noise to the signal. SILMIC series ELNA filter capacitors filter the power fed to the output op-amps to reduce the chances of noise. Finally, high-performance metalized polypropylene film capacitors in the audio path provide excellent high-frequency performance.

A pair of Cirrus Logic Advanced Multi-bit Delta Sigma Architecture 24-bit digital-to-analog converters handles conversion of data from the Analog Device ADSP-21489 SHARC Processor. This powerful processor was chosen for its ability to handle the complex math involved in implementing Finite Impulse Response (FIR) crossovers and equalization on many of the output channels. Audison suggests that the use of FIR filters over Infinite Impulse Response (IIR) processing eliminates phase anomalies associated with configuring and tuning the system to produce a more-coherent soundstage and improved listening experience.

Next-Level Factory Sound System Integration

The Bit One HD Virtuoso is equipped with advanced DE-EQ processing that includes phase analysis. Previous integration processing has been able to undo equalization and signal delay added to the output of an amplifier. The Virtuoso adds the ability to detect all-pass (Phase EQ) processing and apply a correction to produce a time-coherent signal for your installer to work with. The Virtuoso will also detect reverse-polarity speaker wire connections so the installer can swap the wiring and reduce processing requirements.

If your factory audio system doesn’t include an upmixer, the Virtuoso will work in the Automatic Routing Input Setup mode. This configuration sums and corrects EQ and Phase to produce a wide-bandwidth signal. The pass-through mode is best used with factory sound systems that include an upmixer and discrete center channel. No summing is applied in pass-through mode, and inputs are routed through to the outputs with provisions for equalization and filtering, depending on the requirements of the new speakers.

Experience the Audison Bit One HD Virtuoso for Yourself!

If you are shopping for an audio system upgrade for your vehicle, visit your local authorized Audison dealer and ask about adding the new Bit One HD Virtuoso to your system design. Beyond being an extremely capable integration processor, it will allow your installer to configure and calibrate each speaker in your mobile audio system so your listening experience can rival or exceed the detail and accuracy of the most-bespoke of home audio systems.

BMW and Mini owners all over the globe have shown that there is a desire for a better sounding audio system in their vehicles. To meet the performance expectations of these discerning clients, Audison of Italy has developed six drop-in upgrades designed specifically for these vehicles. Best of all, the speaker and subwoofer upgrade solutions use factory wiring and mounting locations, so there are no modifications required. These are the perfect solution for leased vehicles!

Balancing Performance and Efficiency

Designing a loudspeaker requires that the engineer balance low-frequency and high-frequency extension with efficiency and output capability. For example, the upper midrange output may suffer if a driver is optimized to produce more bass. The engineers at Audison have optimized all these criteria for their Prima Series drivers to deliver amazing performance installations using small to moderately powerful amplifiers. As such, their BMW speakers are a perfect stand-alone upgrade with the factory radio or amplifier, or when used with a much more powerful solution like the 85-watts-per-channel AP F 8.9 bit DSP-equipped amplifier.

BMW Speaker Upgrade Solutions

The BMW speakers are broken into two categories: coaxial and component sets. So whether you have a new 2-series and want to upgrade the door speakers or are looking for the dash, front and rear speakers along with a subwoofer upgrade for a 2015 X5 with the Hi-Fi Sound system, there’s a solution from Audison.

The four speaker options are all based on the same basic platform. The 4-inch (100 mm) drivers feature high-quality rigid die-cast aluminum frames that include specific mounting provisions for the doors, the dash center channel or the rear parcel shelf of your BMW or Mini.

To deliver excellent efficiency, the drivers use neodymium magnets instead of conventional ceramic units. The woofer cones are constructed from pressed pulp paper to deliver an excellent balance of rigidity and damping characteristics. The cones are treated with a moisture-resistant finish to ensure their longevity in door installations. The woofers are driven by a large 1-inch (25 mm) fiberglass voice coil former. The large diameter of the coil contributes to the 40-watt continuous, 80-watt maximum power ratings for the drivers. Lastly, they all use a rubber surround instead of foam for an additional improvement in longevity.

The tweeters used in the coaxial and component set solutions once again feature neodymium magnets for excellent efficiency. The diaphragms are made of Audison’s Tetolon silk and cotton dome material to optimize rigidity and damping characteristics to prevent distortion. In the APBMW K4E and K4M component sets, the tweeters have a diameter of 29 mm. Most tweeters in this class, including these vehicles’ stock tweeters, are only 25 mm in size. The larger diameter allows for a nice, low resonant frequency and lower crossover points. The large diaphragm size also improves efficiency.

The component sets include the APBMW CXTM 1 passive filter networks for the tweeters. These filters include 0 and -3 dB output options, and OE-quality connectors are included for wiring. Angled mounting cups for the tweeters are included for rear parcel shelf installations. In the APBMW X4M and X4E coaxial speaker solutions, the tweeters use the same materials but have a diameter of 24 mm. Audison also offers the APBMW A4E accessory kit to allow for the unique installation applications of the F15 chassis X5, F16 chassis X6 and the G30 and G31 chassis 5-series sedans and wagons.

Prima Subwoofer for BMW and Mini Cars and SUVs

The APBMW S8-2 and APBMW S8-4 are 8-inch (200 mm) subwoofer solutions that are a direct drop-in replacement for the under-seat subwoofers found in BMW and Mini vehicles. These subwoofers feature graphite fiber-reinforced baskets with top-mounted neodymium motor structures. A pair of 5-millimeter polyurethane mounting gaskets are included to ensure a perfect seal with the factory enclosure. A 38 mm (1.5-inch) voice coil provides reliable performance at the speaker’s 150-watt power handling rating. The woofers’ cones are made from pressed pulp, and they use a rubber surround for longevity. A fabric cover over the face of the woofer cone prevents coins and rogue french fries from entering the speaker and causing buzzes or rattles. The woofers feature an Xmax specification of 7 mm in each direction for impressive output from the limited space and shallow mounting requirements.

The Audison engineers put some careful planning into the 2- and 4-ohm models. The 4-ohm S8-4 is slightly less sensitive than the 2-ohm model but offers a 40 Hz resonant frequency instead of 45, so it plays deeper. When the 4-ohm woofer is bridged onto a pair of channels from a Prima amplifier, the additional power allows it to play as loudly as the 2-ohm driver. If you plan a system that will use a larger subwoofer (10- or 12-inch) in the trunk or cargo area, the under-seat woofers function well as midbass drivers.
