Design & Build: Slim Elegance Meets Structural Rigidity

The AE309.2 features an 18mm constrained-layer RSC™ MDF/bitumen cabinet that offers superior damping and minimal resonances. Its slim 170mm footprint enables easy placement, while aluminium feet and spike covers ensure stability and floor protection. Available in Walnut, Silk-Touch Matte Black or Matte White, each finish boasts colour-matched trims and magnetic cloth grilles, allowing you to integrate the speakers seamlessly into any décor.

Driver Technology & Acoustic Engineering

At the heart of the AE309.2 are 120mm paper/coconut-fibre cone bass-mid drivers developed using research from the CORINIUM project, delivering a natural, uncoloured tonal balance. The new 29mm soft dome tweeter extends smoothly to 29kHz, offering detailed treble without any harshness. The 2.5-way crossover at 285Hz and 3.8kHz optimises driver integration, while the slot-shaped rear port reduces air turbulence for tight, distortion-free bass.

Sound Signature & Performance

On playback, the AE309.2 unveils a precise, articulate soundstage with impressive scale and depth. The bass is punchy and controlled, thanks to the well-tuned port and stiff cone materials. Midrange is neutral and expressive, rendering vocals and acoustic instruments with lifelike texture. High frequencies sparkle with air and finesse, yet never stray into fatigue, making these speakers equally adept at critical listening and engaging music sessions.

System Matching & Room Integration

With a sensitivity of 89dB and a nominal impedance of 6Ω, the AE309.2 pairs effortlessly with a wide range of amplifiers—from high-current solid-state to warm-sounding tube designs. For best results, allow at least 30cm from the rear wall to the slot port and experiment with toe-in to fine-tune imaging. These speakers thrive in medium to large rooms, filling space with authoritative sound without overwhelming subwoofers or mains.
