The APBX 10 DS, a 10” subwoofer loaded in a 12-litres sealed enclosure, is the line’s “flagship”. It is dedicated to the highest performing Prima systems, using the AP1 D amplifier for the sub section. The speaker’s mechanical excursion of more than 18 mm provides for incredible authority, while the refined Thiele&Small parameters set-up provides the ideal balance for all music genres.
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 Ω dual voice-coil configuration was adopted to exploit the full power of an AP5.9 bit (paralleling voice coils for a 2-ohm load) or with two pairs of AP8.9 bit bridged channels (one bridged pair of channels to each voice coil). The speaker’s 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 Ω voice-coil subwoofer has a powerful motor that maximizes efficiency in combination with the AP8.9 bit amplifier. 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 AP4.9 bit / AP4 D bridged channels, capable of delivering 260 W rms.
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.

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 AP8.9 bit or AP4.9 bit / AP4 D.

Prima’s 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 4Ω 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 AP 1D amplifier using the 540 W RMS delivered on the 2Ω load resulting from the drivers connection in parallel.
The APBX 10 S4S sealed enclosure is the ideal choice to be driven by the new AP F8.9 bit using two channels bridged. Designed to house the single 4Ω voice coil APS 10 S4S subwoofer, it offers an ultra-performing Plug & Play solution boasting all the features that make the Prima boxes unique such as the SSP (Sub Smart Plug) terminal block for a quick connection leaving no room for errors.
The Prima APBX 8 AS2 active subwoofer, with 8-inch driver,features a dedicated high performance amplification module which 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 in the lower side of the spectrum.
The high-level speaker-in input on 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’s 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.
