Audison Prima APS 10 S4S - 10-inch Subwoofer for Compact Sealed Enclosures

The Audison Prima APS 10 S4S is a 25 cm subwoofer that delivers powerful deep bass in very small enclosures from 10 liters. With a single 4-ohm voice coil, it's ideal for Audison's AP F8.9 bit (bridged), including the use of its DSP functions. 400 W RMS and 800 W Peak, combined with a shallow design and efficient ventilation, make it a reliable solution for space-critical installations. Dual setups with two APS 10 S4S are also easily achievable. Available at Carhifi.shop.

Installation & Compatibility

Are you planning a compact, sealed box? The APS 10 S4S is designed precisely for this – from as little as 10 liters net volume. Thanks to the ventilated basket without a central pole piece opening, the sub can be installed close to the rear wall of the enclosure. With its 4-ohm voice coil, it harmonizes particularly well with the Audison AP F8.9 bit (bridged). Using the integrated DSP, you can utilize bass boost and parametric EQ for precise tuning. For more cone area, the sub can also be operated in a dual setup.
