The Prima series of amplifiers and speakers from Audison is highly regarded for its installation flexibility and impressive performance. The most recent additions to the Prima line are three new component subwoofers and five loaded subwoofer enclosures. Like the Prima amps and speakers, the new Audison Prima subwoofers are designed as a perfect upgrade to any factory-installed audio system.

Prima Shallow-Mount Subwoofers

The new Prima subwoofers include two eight-inch models and a 10-inch. The APS 8 D and APS 10 D feature dual four-ohm voice coils with suspension designs optimized for compact sealed enclosures. The APS 8 R subwoofer has a single four-ohm voice coil and is intended for use in a bass-reflex (vented) enclosure.

All three subwoofers are optimized to provide excellent output. The shape of the woofer cone is angled to clear the spider mounting ledge to increase excursion capabilities. The APS 8 R and APS 8 D are specified as having an Xmax (one-way cone travel limit) of 8.8 mm and the APS 10 D can move 11 mm in each direction.

The APS subs feature a vented pole piece that allows hot air to escape from the inside of the motor structure and peripheral vents underneath the spider mounting plateau to keep the outside cool. This second row of vents allows reliable operation when sub is mounted near the back wall of an enclosure.

The APS 10 D has a mounting depth of 3.46 inches and stands out 1.23 inches from the mounting surface. The driver is optimized to function well in enclosures with a volume as small as 10 liters (0.35 cubic feet). The APS 8 R and APS 8 D subwoofers have a mounting depth of 3.11 inches and extend forward 0.98 inches. The APS 8 D will work in 7.5-liter (0.26 cubic-foot) enclosures while the APS 8 R needs a mere 8.5-liter (0.30 cubic-foot) vented design. The larger vented enclosure will provide roughly 4 dB more output around 50 Hz for a given input signal.

Loaded Subwoofer Enclosures

Each of the new subwoofers is available loaded in a custom-tailored enclosure. The enclosures are constructed from medium-density fiberboard and include internal bracing for excellent rigidity. Rounded corners give the enclosures a bespoke look that blends nicely with modern vehicle interiors.

Your installer can mount the enclosure with the sub facing upward into the listening area for excellent upper bass impact or use the provided mounting feet to fire the sub down into the floor to enhance low-frequency output. Audison calls this design 2 Sides 2 Sounds or 2S² for short. The optional mounting feet include hook-and-loop fasteners to help keep the enclosure in place.

The terminal cup on the side of each enclosure includes a connector that makes the system instantly compatible with Audison Prima Plug & Play connectors. Of course, high-quality spring-loaded terminals are also included so the enclosures can be used with any amplification solution.

Prima Active Subwoofer Enclosures

Audison has also introduced eight- and 10-inch sealed enclosures with built-in amplifiers. The unique Class D amplifiers feature a design called he·li or High Efficiency-Low Impedance. The drivers used in the powered enclosures have the same mechanical design as their APS 8 D and APS 10 D brethren but use low impedance voice coils. This design allows the amplifiers to work directly with the voltage supplied by the vehicle electrical system and negates the need for, and efficiency losses associated with, a switching power supply. The result is 250 watts for the APBX 8 AS and an impressive 400 watts for the APBX 10 AS enclosures.

Both amplified subwoofer enclosure solutions include electronic variable crossovers, adjustable phase and a bass boost circuit. The amplifiers will accept speaker-level inputs or a preamp signal and include automatic turn-on circuitry for use when connected to a factory-installed audio system. Electrical connections are on a quick-connect plug that allows the enclosure to be removed easily. Both enclosures include an HRC AP remote level control to allow you to adjust the bass level from the front seat.

Enclosure Dimensions:

Model Width Height Depth

APBX 8 R 18.62” 13.15” 5.16”
APBX 8 DS 14.84” 13.15” 5.16”
APBX 8 AS 15.2” 11.73 6.22”
APBX 10 DS 18.58” 13.15” 5.59”
APBX 10 AS 18.11” 13.31” 6.22”

Adding a subwoofer is the best and easiest way to improve the performance of your stereo. Audison’s new Prima subwoofers provide you the option of a drop-in solution or give your installer the opportunity to create something unique for your vehicle. Visit your local authorized Audison retailer to experience the new Prima subwoofers for yourself.

Audison has embraced the digital domain with its Full DA HD series of products. By way of a backstory, we’ve been able to enjoy our favorite music on compact disc since August 1982. Fast forward to 1995 and we saw the birth of SACD, DVD-Audio and DAD formats with higher sampling rates and greater resolution. These formats marked the beginning of the high-resolution audio industry, and the Audison Full DA HD systems can now take advantage of these formats.

The Full DA HD Philosophy

In a conventional audio system, digital music is converted to analog before it leaves the source unit. Our DSP converts it back into digital, processes the signal, and then converts it back to analog to send to our amplifiers. Audison was wise enough to ask whether our music could remain in the digital domain from the source, right up to our amplifiers.

Full Digital Signal Source

The Full DA HD philosophy starts with the amazing bit Play HD. This digital media player is designed specifically for automotive applications. It will play FLAC and WAV files encoded at 96 kHz and 24-bit resolution from an internal 240GB SSD drive or a USB stick. The system is also compatible with AAC, MP3 and OGG audio formats and a variety of 1080p video formats including AVI, DivX, MKV and Xvid formats.

The bit Play HD includes an easy-to-use graphical interface that can integrate with an existing color infotainment screen. If you don’t have a display available, you can control the system from your iPhone or Android phone using a dedicated application. Audison kindly includes a Wi-Fi dongle to make connecting to your phone easy.

The bit Play HD includes a Toslink output that supports the full 96kHz/24-bit file information. This digital output can connect to any Audison DSP with a Toslink input for crystal-clear sound.

Full Digital Signal Processing

With the introduction of the bit One HD, installers can now configure equalization, crossovers, signal delay and level control for up to 13 channels in the digital domain without the need for any analog conversion. Equipped with state-of-the-art signal processing and the ability to handle high-resolution files, the bit One HD can transform almost any speaker configuration into a studio reference experience.

The output of the bit One HD includes two sets of RJ45 connectors. The first pair covers channels one through eight and the second pair handles channels nine through 13. The Toslink signal on these connections remains in the digital domain and connects directly to any of the Audison Full DA HD compatible amplifiers.

Full Digital Amplification

Audison has two amazing amplifier families directly compatible with the Full DA HD output of the bit Play HD. The Thesis TH uno, TH due and TH Quattro will accept the AD Link and AC Link inputs right out of the box. The Voce Series AV5.1k HD includes a pair of AD and AC Link inputs and the AV uno, AV due, AV Quattro and AV 5.1k are upgradable with the AV bit IN HD digital interface.

In all applications, the conversion from digital to analog takes place inside the amplifier to produce an audio signal with exceptional bandwidth and freedom from background noise. Each amplifier includes a digital address control, allowing for up to 10 amplifiers to be on the AC Link network and recognized by the bit One HD. The control panel handles routing of signals to the appropriate output channel.

System Options and Accessories

The bit Play HD includes the DRC MP controller that can act as master volume control and provides access to different presets within the system. If you drive a European vehicle that uses the MOST audio protocol, the bit DMI interface will provide a full-bandwidth optical Toslink signal to one of the two inputs on the bit One HD.

What Are the Benefits of a Full DA HD System?

Conventional analog pre-amp level signals are often in the millivolt range and can pick up unwanted interference as the interconnect cables run past computers, sensors or high current wiring in the vehicle. Digital signals are functionally impervious to radiated noise. The difference is akin to TV manufacturers describing their screens as having blacker blacks. Fire up your bit Play HD, pick a song and enjoy!

Experience Audio Like Never Before

If you are searching for an exceptional audio experience for your vehicle, visit your local authorized Audison dealer and ask about the Full DA HD system. They would be happy to design a sound system that offers exceptional detail, accuracy and realism. Even if you already have a system, ask for a demonstration. We know that you will be impressed.
