audison APBX 8 AS2The 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 2S (2 Sides 2 Sounds) design, the Plug & Play terminal block and ultra compact size.

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.

Features
- Integrated 250 W RMS 0.4 ohm2 D-Class amplifier featuring he-li technology
(high efficiency / low impedance) without switching power supply, for a
performance next to ideal. - 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. - Butterworth low-pass filter at 12dB/Oct. with variable cutting frequency (50-300 Hz), phase control (0-180°), and adjustable bass-boost
0÷6 db 45Hz. - Defeatable filter to use the sub-dedicated output of a bit or AP bit processor.
- High-level audio input on multi-pin connector for maximum OEM
integration and low level on RCA for aftermarket sources. - ART turn-on function (Automatic Remote Turn-On) is selectable among Remote-in, Hi-level, Audio signals.
- Box with ultra-low profile (6.22 in. / 158 mm) in air suspension, designed to take full advantage of the performance of the 8-inch APS 8 DL
high-impedance driver. - The SSP (Sub Smart Plug) terminal block is provided with a Plug & Play connector to be able to disconnect the box easily and safely.
- The 2S² (2 Sides / 2 Sounds) design provides the ability to select between
Down-Firing positioning to increase the low-frequency extension and
Up-Firing installation to obtain more punch and definition. - Down-firing leveling feet with Velcro inserts included for a secure grip with the carpet, ensuring extreme ease of removal.
- Rounded corners allow easy placement in the trunk and act as a
reinforcement to reduce enclosure resonances. - Exclusive design of the cone, dust-cap, and basket geometry to achieve a wide linear excursion (9 mm in one direction), keeping the depth required for assembly to a minimum.
- HRC AP remote control included.
- Sturdy metal grille is included, for total protection of the subwoofer driver.

Slow charge

Super slow charge takes. Takes almost 2 hours to charge 50%

Great & very convenient charger, only one issue
Color: 2Black
This charger wound up being everything I hoped for - it charges a Galaxy S26 fast and works with a wireless charger compatible phone case. Despite all this, I'm taking a star off for the fact that *you have to buy an aftermarket converter* for it, because for some ridiculous reason, its cable end isn't a USB type A (which your previous phone's converters and probably many of your home's outlets use), but requires a 30W (no less) USB-C. So, there goes another $10 for the converter. Actually you'll probably want to buy two, for at least two rooms at your home, so there goes another $20.

Absolute trash.
Color: 2White
Neither charger worked on arrival... Quite disappointed. Now I'm steering away from every item that has the same markings. Just shelling out for a better quality charger... Not worth it at all... It's incredibly irritating having 2 DoA chargers... Tried on 5 different phones and 10 different blocks.

Charges slowly and makes phone/charger really hot.
Color: 2White
I thought these would be great, but they aren't. I use them with a 25w charging block, but they charger my iPhone so slowly! I can't really use the phone for any games or even scrolling TikTok while the charger is on it because the phone uses power faster than these mag-chargers can charge the phone. The phone also overheats when this charger is on it.
Never had that problem with a lightning charger.
Basically these are only good when you won't be using the phone, and it takes a long time. Not very happy with them.
