Audison Prima APS 10 S4S 10" Single Voice Coil Subwoofer — 400W RMS / 800W Peak, 4Ω, Compact Sealed Enclosures

The Audison Prima APS 10 S4S is a 10-inch (250 mm) shallow subwoofer with a single 4Ω voice coil, built to deliver strong output from small sealed enclosures starting at about 10 litres. It uses Prima's cone-dustcap-basket geometry for large excursion with minimal mounting depth. It handles 400W continuous (RMS) and 800W peak power, and its single-coil design suits simple wiring and custom enclosures with one or two drivers.

Key Features

• 10" (250 mm) subwoofer with a single 4Ω voice coil
• Power handling of 400W continuous / 800W peak
• Designed for sealed enclosures from 10 to 12 litres
• 60 mm (2.36") voice coil, Re of about 3.7Ω and a high-density ferrite magnet
• Water-repellent pressed paper cone, with a profile developed using FEM simulation and the Klippel scan vibrometer
• Push connectors for easy wiring and configuration

Technical Highlights

Output depends on excursion, so Prima's cone, dust-cap and basket geometry lets the cone move a lot of air while the driver stays shallow enough to sit close to the back wall of the box. The mounting centre-to-centre distance is 255 mm (10.04"). Audison suggests pairing it with its AP F8.9 bit amplifier (2 channels bridged, 260W RMS), using the amplifier's bass boost and parametric EQ.

Ideal For / System Fit

• Compact sealed boxes where space is limited
• Custom enclosures with one or two 10" drivers
• Systems with a DSP amplifier that can bridge a pair of channels into 4Ω

Not a plug-and-play box: it is a driver only, so it needs an enclosure of at least about 10 litres and a suitable amplifier, and professional installation is recommended.

Installation Note

Build or buy a sealed box of 10–12 litres. Wire the single 4Ω coil directly, or wire two drivers to the load your amplifier is rated for. Use a low-pass filter and check the amplifier's rated load before connecting.

What's Included

1 x Audison Prima APS 10 S4S 10" single voice coil subwoofer (confirm the supplied hardware with your supplier)

Precautions

• Match amplifier power and load to the 400W RMS / 800W peak rating and 4Ω impedance
• Use a sealed enclosure of at least about 10 litres
• Do not run it unfiltered at high levels; use a low-pass filter
• Professional installation is recommended
