Beosound A9 (5th Gen) — sculptural design with room‑filling performance
Bang & Olufsen's Beosound A9 balances showpiece aesthetics with serious sonic muscle. The circular, multi‑driver array—including a dedicated 8" woofer with a 400 W Class D amp and extensive per‑driver amplification—delivers deep, controlled low end, articulate mids and refined highs, producing an expansive, enveloping soundstage ideal for 15–100 m² rooms. The system's DSP suite, notably Active Room Compensation and Adaptive Bass Linearization, keeps bass tight and voices natural while preserving dynamic punch and clarity.
Beyond sound, the A9 is a customizable objet d'art: precision‑milled aluminum hardware, oak legs and swappable fabric covers let it sit as furniture or focal artwork—an approach celebrated by Best of High End and highlighted in limited editions covered by The Ear. Connectivity is comprehensive—Dual‑band Wi‑Fi, Bluetooth 5.3, AirPlay, Spotify Connect, Google Cast, TIDAL Connect and USB‑C line‑in—so it fits modern multiroom and streaming setups, as noted by ecoustics.
For buyers seeking a statement speaker that pairs museum‑quality design with powerful, well‑engineered sound (final score: 92.3), the Beosound A9 is a compelling choice for living rooms, open‑plan spaces and design‑forward systems.
Pros
- Deep, controlled bass and strong dynamics driven by a dedicated 8" woofer and high‑power amplification, yielding room‑filling low end and headroom.
- Iconic, highly customizable design and premium materials (aluminium, oak legs, fabric/wool) that make the speaker a design object as well as an audio system.
- Comprehensive modern features and connectivity—Active Room Compensation, Adaptive Bass Linearization, AirPlay, Spotify Connect, Google Cast and USB‑C input—making it flexible for multiroom and streaming setups.

Cons
- Premium pricing positions the A9 for luxury buyers rather than value‑focused shoppers.
Sound Quality
92/100
Bass
93/100
Single 8" woofer driven by a dedicated 400 W Class D amp plus extensive Class D power across drivers and Adaptive Bass Linearization and Active Room Compensation. Specs and recommended room size (15–100 m²) imply strong low-frequency authority and room-filling capability; score placed in the 'mid-tower' excellent band given the active DSP and high amp power.
Mid
92/100
Multiple dedicated mid-range drivers (2 x 3" mid-range and 2 x 1½" full-range) with per-driver amplification and room compensation indicate natural, well-controlled mids and coherent crossover regions. Design and DSP point to excellent vocal presence and timbral fidelity for a single-cabinet active floorstander.
Treble
91/100
Multiple tweeter complements (2 x ¾" tweeters) and significant DSP/control suggest extended, refined treble with good detail and low harshness. The system's emphasis on adaptive compensation and high total power supports clean high-frequency response at listening levels.
Soundstage Imaging
93/100
Circular, multi-driver layout with stereo-pairing capability and Beolink multiroom support implies very wide, enveloping sound and excellent depth when paired or placed correctly. Active room compensation and networked stereo pairing will enhance stage width and layering compared with a simple passive tower.
Dynamics
91/100
Very high aggregate amplifier power (total ~1500 W listed) and a dedicated woofer amp yield strong macro- and micro-dynamic ability and headroom. Single 8" woofer design means slam is powerful but not at the absolute reference multi-woofer level, so dynamics are excellent but not reference-exceptional.
Show Less
Build Quality
96/100
Premium materials listed (aluminium, wood, fabric/wool, polymer) and B&O's high-end manufacturing tradition support exceptional fit-and-finish and cabinet engineering. The heavy-duty amplifiers and integrated DSP hardware further indicate a very well-engineered product.
Features Connectivity
95/100
Extensive connectivity: Dual-band Wi‑Fi (2.4/5 GHz, 802.11 a/b/g/n/ac/ax), Bluetooth 5.3, AirPlay, Spotify Connect, Google Cast, TIDAL Connect, Ethernet, USB‑C line-in, Beolink multiroom and Active Room Compensation. Rich feature set and modern codecs plus on-device and app control place this at the top end for connectivity and features.
Value for Money
78/100
At the listed price (~€/$4,650), the A9 targets premium buyers; build, DSP, and features justify a high price but peers in this range can offer more woofer complement or lower-cost alternatives. Without third‑party review praise visible here, value is good for luxury buyers but not an objective bargain.
