Its Dynamic Bass Tracking (DBT) maximizes bass performance at high volumes, while the water-repellent pressed paper cone ensures durability. Compact and easy to install, it offers customizable sound controls including adjustable low-pass filter, phase, and bass boost, making it the perfect upgrade for audiophiles seeking powerful, crisp, and dynamic bass. ## Description 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. Features - Integrated 250 W RMS @ 0.4 Ω 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. ## Features - Output Power (RMS): 250W Continuous Power - Output Power (RMS): 500W Peak Power - Impedance: 0,4 Ohms - Magnet: Ferrite - Cone: Water-Repellent Pressed Paper ## Technical Specifications | Specification | Value | |---------------|-------| | Additional Features | Dynamic Bass Tracking | | Age Range Description | Adult | | Antenna Location | For Surround Sound Systems | | Asin | B07J2PXQTD | | Audio Driver Size | 8 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Surround | | Battery Average Life | 1 Hours | | Best Sellers Rank | #424,977 in Electronics (See Top 100 in Electronics) #435 in Car Enclosed Subwoofer Systems #655 in Home Audio Subwoofers | | Brand | Audison | | Built In Media | APBX-8-AS2 | | Color | Black | | Compatible Devices | Smartphone, Tablet, MP3 Player, Desktop, Television, Projector, Laptop | | Compatible With Vehicle Type | & SUVs, Select Cars, Truck | | Connectivity Protocol | RCA | | Connectivity Technology | XLR | | Control Method | Touch | | Controller Type | Remote Control | | Customer Reviews | 4.9 4.9 out of 5 stars (14) 4.9 out of 5 stars | | Enclosure Material | Wood Or Metal | | Frequency Response | 35.35 Hz | | Impedance | 0.4 Ohms | | Is Waterproof | FALSE | | Manufacturer | Audison | | Model Name | APBX-8-AS2 | | Model Number | APBX-8-AS2 | | Mounting Type | Play,Plug Mount | | Mp3 Player | No | | Number Of Audio Channels | 2.0 | | Number Of Circuits | 1 | | Number Of Items | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 500 Watts | | Speaker Size | 8 Inches | | Speaker Type | Subwoofer | | Specific Uses For Product | musical listening | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 8 Inches | | Tweeter Diameter | 1 Inches | | Unit Count | 1.0 Count | | Warranty Description | 1-Year Manufacturer Warranty | | Warranty Type | Limited | | Water Resistance Level | Water Repellent | | Woofer Diameter | 8 Inches | ## Product Details - **Audio Output Mode:** Surround - **Brand:** Audison - **Connectivity Technology:** XLR - **Frequency Response:** 35.35 Hz - **Speaker Maximum Output Power:** 500 Watts ## Images ![APBX 8 AS2 Prima Series 8" Active Sub Box with Dynamic Bass Tracking - Image 1](https://m.media-amazon.com/images/I/7139kCvTyJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great addition *by on Reviewed in the United States September 15, 2022* Great sound In such a little box easy install too!! No problems ### ⭐⭐⭐⭐⭐ Compacte et son de qualité *by on Reviewed in France May 23, 2022* Étant audiophile, j'ai vraiment analysé ce caisson. Très bon caisson, il est bien équilibré et musical ! Je n'en attendais pas autant vu sa taille.De 30hz à 100hz le son est pratiquement au même niveau sur toute la plage de fréquence dans un habitacle petit de type Citroën C2.C'est étonnant d'avoir autant de profondeur vu qu'il passe au millimètre sous un siège et qu'il ne s'agit que d'un 8 pouces.Il déborde de puissance.Pour conclure je pense que le caisson est parfait pour celles et ceux qui veulent de "vrai" basses dans une dimension très réduite. Il explose haut la main ses concurrents qui font des caissons ultra plat de dessous de siège. On a envi de le comparer à de gros caissons vu le son qu'il produit, mais il ne faut pas oublier qu'il est petit donc il bave un peu lorsque le volume de la musique est très fort. Je pense que la puissance de l'ampli est surdimensionné par rapport à la membrane. ### ⭐⭐⭐⭐⭐ Top *by on Reviewed in Germany December 27, 2025* Top immer wieder gerne 👍 ## Frequently Bought Together - Audison APBX 8 AS2 Prima Series 8" Active Sub Box with Dynamic Bass Tracking - mankk 166 Pcs Wire Ferrules Kits Silver Plated Copper Crimp Terminal Connector 8 Sizes AWG (1/0 2/0 2 4 6 8 10 12) Sleeves Insulated Cord Pin End Terminal M-020 - Sanuke 10pcs 1/0 AWG-3/8 Battery Lugs, UL Listed Heavy Duty Wire Lugs Ring Terminal 0 Guage terminals Battery Cable Ends/Terminal Connectors with 3:1 Heat Shrink Tubing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/384592679-apbx-8-as2-prima-series-8-active-sub-box-dynamic](https://www.desertcart.ie/products/384592679-apbx-8-as2-prima-series-8-active-sub-box-dynamic) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-30*
