Acoustic Energy AE Sub Subwoofer Matte White

Acoustic Energy AE Sub — Active Subwoofer

The AE Sub is Acoustic Energy's dedicated active subwoofer, purpose-built to partner with their acclaimed 100 and 300 Series loudspeakers — though it will happily underpin any system that needs authoritative low-frequency reinforcement. Whether you're filling out a two-channel hi-fi setup or anchoring a full home cinema system, the AE Sub adds genuine depth and physical impact without dominating your living space.

At its core is a large 12-inch long-excursion driver with a doped and stiffened pulp-fibre cone, powered by a 250W RMS Class D amplifier. This combination pushes usable bass response down to a claimed 26Hz — deep enough to feel the rumble of a cinema soundtrack or the lowest registers of a pipe organ. The sealed, downward-firing cabinet design keeps things tight and controlled, avoiding the boomy, one-note bass that plagues many ported subwoofer designs. You get speed, texture, and tunefulness rather than just volume.

Comprehensive Connectivity

The AE Sub caters to virtually any system configuration. Stereo line-level RCA inputs cover standard preamp or processor connections, a dedicated LFE input handles home cinema duties via your AV receiver, and high-level speaker binding posts allow integration with amplifiers that lack a dedicated subwoofer output. This flexibility makes the AE Sub a genuinely versatile addition whether your system is a simple stereo pair or a full surround setup.

Seamless Room Integration

Getting a subwoofer to blend invisibly with your main speakers is often the biggest challenge. The AE Sub makes it straightforward with a continuously variable crossover (40–180Hz), 0–180° phase control, and an independent volume dial. Together, these let you dial in a seamless handover to your main speakers regardless of room size or placement. An auto on/off function detects incoming signal and powers the unit down during periods of inactivity, so there's no need to reach behind the unit to switch it on and off.

Compact and Living-Room Friendly

At just 360mm in each dimension — a perfect cube — the AE Sub is easy to tuck beside furniture or into a corner. It ships with carpet-piercing spikes for solid coupling on carpeted floors, plus rubber caps for use on hard surfaces. Available in Matte Black or Matte White to suit your room.
