Acoustic Energy AE520 Floorstanding Speakers – Pair
The Acoustic Energy AE520 floorstanding speakers are the pinnacle of the AE range, delivering breathtaking musical realism, scale, and power. Designed for enthusiasts who demand uncompromising performance, these flagship towers combine cutting-edge driver technology with elegant craftsmanship to produce sound that is as refined as it is authoritative.
Flagship sound with commanding presence
The AE520 is engineered to fill medium to large rooms with expansive, immersive audio. Its tall, slimline profile hides a powerhouse within—capable of delivering room-shaking dynamics while still preserving the fine textures of delicate recordings. This balance of impact and nuance makes it a true all-rounder for every genre of music.
Triple bass drivers for deep, controlled lows
Equipped with three dedicated 125mm carbon fibre woofers, the AE520 digs deep into the low frequencies, producing bass that is fast, punchy, and highly controlled. The rear-mounted triangular port enhances low-end extension without introducing muddiness, ensuring your music retains energy and drive even at high volumes.
Midrange purity with dual dedicated drivers
At the heart of the AE520 are two carbon fibre midrange units, each housed in its own sealed enclosure for ultimate accuracy. This dedicated mid-band reproduction brings lifelike clarity to vocals, strings, and acoustic instruments. With oversized voice coils for maximum precision, the speakers present midrange detail with astonishing realism.
High-frequency finesse with carbon fibre tweeter
For seamless integration across the spectrum, the 25mm carbon fibre dome tweeter delivers crisp, open treble. Its waveguide design ensures smooth dispersion, blending effortlessly with the mid and bass drivers. The result is a soundstage that is both coherent and three-dimensional.
Resonance-free cabinet construction
The AE520 features 18mm Resonance Suppression Composite (RSC) cabinets, purpose-built to minimise vibration and coloration. Despite their commanding performance, the speakers maintain a slender footprint, making them easy to accommodate in modern living spaces. Finishes include Piano Black Gloss, Piano White Gloss, and American Walnut veneer, combining timeless style with robust engineering.
