AUDISON Audison 10" 800W Slimline Loaded Subwoofer Box-SB10SA1
$399.99
The Audison SB10SA1 is a great option for adding powerful bass to your car audio system. This sealed Aerpro 10″ Loaded Slimline Subwoofer Box is designed to save space, with dimensions of 341mm (H) x 485mm (W) and a tapered depth of 85mm to 135mm, making it easy to install in most vehicles. With an internal volume of 11.31 litres and a 232mm mounting cutout, it provides an ideal setup for clean, punchy bass.
The APS10D 800W Subwoofer used is designed to deliver maximum performance in a sealed enclosure with ultra-compact volumes, from 10 lt. to 12 lt. The dual voice coil features push connectors for ease of wiring and configuration. Prima subwoofer components have been developed with a primary goal: to deliver high output in tight spaces. Output is a matter of excursion; the more air the cone moves, the more output. However, reduced mounting depth traditionally has meant low excursion.
Prima subwoofers employ a special cone-dust cap-basket geometry which guarantees large excursion of the mobile group while keeping the mounting depth to a minimum. The surround and spider have been carefully designed to prevent the “rocking – -mode” phenomenon. The cooling circuit has been designed with air vents on the basket underneath the spider, eliminating the need for vents on the bottom – plate. This allows the subwoofer to be mounted close to the back wall of the enclosure, making the most of the reduced mounting depth.
Please Note: The slimline subwoofer box used is the Aerpro SB10S and is not made by Audison.
Features:
Fits easily in most vehicles without taking up too much space, thanks to its slimline dimensions and tapered depth.
Sealed Enclosure Enhances sound clarity and delivers tight, punchy bass for a more precise audio experience.
Durable 12mm MDF Construction ensures long-lasting performance while minimising vibrations for better sound quality.
Spring-Loaded Banana Socket Terminals allow quick, secure, and hassle-free wiring connections.
Black Carpet Finish blends seamlessly with most car interiors while protecting the enclosure from scratches and wear.
Specially designed cone, dust cap, and basket geometry ensure long linear excursion capability (11mm, One Way) keeping mounting depth to a minimum.
Air vents on the basket underneath the spider, eliminating the need for the central pole vent allowing mounting close to rear wall of enclosure.
Massive motor assembly, optimized with FEM (Finite Element Modelling) for perfect control under high power, high excursion conditions.
Water-repellent pressed paper 10-inch cone, featuring a profile developed with FEM simulation and optimized with the Klippel Scan Vibrometer.
Designed and engineered to deliver exceptional performance in a sealed enclosure, ensuring powerful bass and precise sound reproduction.
A steel mesh grille and plastic gasket are integrated to protect the subwoofer, ensuring durability and safeguarding against damage.

The Prima APBX 10 AS2 active subwoofer, with the 10-inch driver, features a dedicated high-performance amplification module that enhances all the passive box technologies, such as the 2S²(2 Sides / 2 Sounds) design, the Plug & Play terminal block and ultra-compact size. The amplification module, with power outputs of 400W RMS, is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC-DC voltage booster reaches the impressive 90% efficiency level, very close to the theoretical limit of the D-Class. New input stage DBT (Dynamic Bass Tracking) technology allows 100% use of the he-li (High-Efficiency Low Impedance) amplifier power and to enjoy a tense and dynamic bass even at very high listening volumes. Eliminating the voltage booster was made possible thanks to the development of the new dual coil drivers, which inherit all the technological background of the Prima subwoofers, but differ for the ultra-low impedance (0.16 ohms for APBX 10 AS). This feature ensures a perfect synergy with the he-li (High-Efficiency Low Impedance) technology, maximizing the combination of amplifier, speakers, and sealed box, to obtain low, powerful, and crisp frequencies. The controls section is complete and provides optimal regulation of the low-frequency emission in the car cabin. The Butterworth low pass filter at 12dB/Oct. with variable cut-off frequency (50-200 Hz) can be bypassed when used with an AP bit processor with pre-out output dedicated to the sub. The adjustable bass-boost control (0 ÷ 6 dB) at 45 Hz allows the user to emphasize the response on the lower side of the spectrum. The high-level speaker-in input on the multi-pole connector eases the integration with OEM audio systems while the low-level input on RCA is dedicated to the connection with after-market sources. The subwoofer automatic turn on/off function ART (Automatic Remote Turn-On) can be configured to be controlled by the source remote signal, by the voltage variation on the high-level input, or by the audio signal on both inputs. Phase control (0-180°) completes the equipment. The SSP (Sub Smart Plug) terminal block is provided with a single Plug&Play connector to be able to disconnect the box easily and safely.

The APBX 8 DS loaded enclosure provides the highest performance/ size ratio. For this purpose an 8.5 lt. sealed enclosure with a 4+4 ohm dual voice-coil configuration was adopted to exploit the full power of an AF M5.11 bit (paralleling voice coils for a 2 ohm load) or with two pairs of AF C8.14 bit/AF M8.14 bit bridged channels (one bridged pair of channels to each voice coil). The speakers high excursion capability allows the use of the proprietary BASS BOOST of AP bit amplifiers to make use of all the available power for rich and dynamic bass.

The APBX 8 R loaded enclosure was developed with reflex loading, with tuning designed to concentrate SPL in the lowest frequency range. The aim was to exploit the natural boost in output found in most cars below 60 Hz known as cabin gain. The 8-inch single 4 ohm voice-coil subwoofer has a powerful motor that maximizes efficiency. The low-resonant frequency of the subwoofer, matched to the reflex enclosure keeps excursion low within the entire audio spectrum, allowing also the use with a pair of AF C4.10 bit/AF C4D/AF M4D bridged channels, capable of delivering 260 W rms.

Audison – The Epitome Of Instinctive InnovationSince 1987 Italian audio virtuoso Audison has been crafting some of the world’s finest mobile electronics. It firmly believes that sound reproduction is a fascinating world where emotion and technology cohabit. Like any form of art, the greatest result is achieved when these two values embrace at their peak. Following this dogma, every project Audison develops is conceived with an attitude drawing from its love for music and a desire to challenge the existing standards. As Audison say, it’ll forever follow its istinto innovative.
Voce II Series - Giving Sound It's True VoiceRepresenting a monumental leap forward in car audio innovation, the Voce II range is directly inspired by Audison's superb flagship Thesis series. So when Audison claim that the Voce II range is born from Thesis excellence; you can rest assured it's not just some hastily conjured marketing hype. Indeed every component of the Voce II line has been developed with the same meticulous methodology that made Audison's Thesis range famous around the world. Employing advanced acoustic simulation software throughout the entire design process, the Voce II components then underwent a rigorous regime of electrical, physical, acoustical and comparative listening tests; both in-lab and in-car. This refinement process ensures that Voce II range delivers uncompromising audio performance, while remaining practical and versatile to satisfy the high-end car audio enthusiast.
Asked recently what the Voce II range stood for, technical director Luca Girotti explained "Voce II, the second generation of our iconic Voce line of speakers, challenged ourselves to rethink how we design, test and manufacture speakers. We've revamped materials, supply chains, assembly techniques and packaging. Our goal was to "unlearn” in order to further innovate, and to "reinforce our expertise" where we knew we were on the right track. This dedication ensures that every aspect of Voce II range not only meets but exceeds the sophisticated demands of today's car audio enthusiasts."
