Subwoofers

400W RMS • 4 Ohm

Prima compact subwoofer family expands with the introduction of the new 25 cm (10 in.) APS 10 S4S, optimized for enclosures with a reduced volume starting from 10 liters. The configuration of the single 4 ohm voice coil makes it ideal to be driven by the new AP F8.9 bit amplifier with built-in DSP that delivers an outstanding 260 W RMS with two channels bridged. Also interesting is the possibility to create custom enclosures with two APS 10 S4S driven by the AF M1D amplifier using the 540 W RMS delivered on the 2 ohm load resulting from the drivers connection in parallel.

The APS 10 D is designed to deliver maximum performance in a sealed enclosure with ultra-compact volumes, from 10 lt. to 12 lt. The dual voice-coil and single voice coil versions feature push connectors for ease of wiring and configurations. 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-dustcap-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.

Designed for tight spaces and dynamic performance, the AV 10 D2 II delivers powerful, articulate low frequencies with the precision and control that define the VOCE II line. Its dual 2-ohm voice coil configuration provides greater flexibility for low-impedance system design, allowing optimal power transfer from high-performance amplifiers. The subwoofer features a 1.5-inch CCAW voice coil, FEM-optimized motor assembly and a die-cast aluminum basket with integrated cable-routing hooks—each detail engineered to ensure stability, thermal efficiency and long-term reliability. The extended-profile dust cap improves cone rigidity and damping, while the internal Radial Reinforcement Framework strengthens the mechanical structure during high-excursion operation. Airflow Venting Cooling technology ensures effective heat dissipation, preserving performance even under prolonged stress. Optimized to perform at its best in compact sealed enclosures (12–14 L / 0.4–0.5 ft³), the AV 10 D2 II delivers deep, clean and fast bass, ideal for systems where space is limited but sonic expectations are high. It is more than a compact subwoofer, it is a VOCE II-class component built to bring the emotion of music into every detail of your sound system.

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.

With the aim of providing high acoustical output even when used with lower power, the APS 8 R was designed for use in an 8.5-litres reflex enclosure, with tuning between 30 and 40Hz. The APS 8 R has been specifically developed to be combined with either the AF C8.14 bit or AF C4.10 bit / AF C4D / AF M4D. 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.

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 Prima APBX 8 AS2 active subwoofer, with the 8-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 250W 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. 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 an 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.
