Verdict

The Bang & Olufsen Beosound A9 (5th Generation) is an iconic, luxury wireless home speaker masquerading as a modern art piece, packing a massive 1,500-watt total output across seven individually amplified drivers: one 8-inch woofer, two 3-inch mid-range drivers, two 1.5-inch full-range units, and two 0.75-inch tweeters. Operating across a wide 33 Hz to 23 kHz frequency range with a maximum SPL of 100 dB, its standout advantages include powerful room-filling sound, seamless Active Room Compensation to tune acoustics based on physical placement, and future-proof wireless connectivity via Wi-Fi, Bluetooth 5.3, AirPlay 2, and Chromecast. However, despite being a masterful centerpiece, it suffers from a lack of true portability due to its substantial weight of 33 pounds and reliance on a standard mains power cable, coupled with a highly restrictive luxury price tag and an interface that lacks a physical remote control.

What customers dislike about Bang & Olufsen Beosound A9?

  • Extremely high, prohibitive premium price tag that makes it a massive financial investment.
  • Despite having a built-in recessed handle, its large dimensions and heavy weight (around 15 kg) make it bulky and not truly portable outside the home.
  • Light-colored fabric covers are highly susceptible to dirt, stains, and pet hair, and replacement covers add to the expense.
  • Lacks a physical dedicated remote control, making users heavily reliant on a mobile app or direct device interaction.
  • Limited physical input options, with modern generations omitting standard 3.5mm auxiliary ports in favor of line-in RCA or strictly wireless playback.
