We Linked 150 of Ikea’s $10 Speakers to Make a Wall of Sound
WIRED attempts what even the Swedish brand hasn’t: making a sonic monolith using scores of the cheapest Bluetooth speakers on the market. Can you have too much of a small thing?
Ikea allowed reporters to connect up to 150 of its £10 Bluetooth speakers, nicknamed Kallsups, to create a massive wall of sound in London. The spokesperson noted this hadn't been attempted before, but agreed to the experiment and even offered to connect up to 150 speakers without any issues. However, one of the speakers arrived broken during shipping, leaving the reporters with 149 working speakers instead of the full 150.
The process of linking the speakers together was surprisingly simple. Once a single speaker was paired with a music device, such as an iPhone, it could be added to a chain by powering on another speaker while music was playing and holding down the Play button until it entered "multi-speaker" mode. This allowed the reporters to connect all the Kallsups in about 30 minutes, well below what they had anticipated.
Despite their limited sound quality and low volume at low volumes, the Kallsups worked surprisingly well together, particularly for playing acoustic tracks. As more speakers were added, the sound grew in scale, with the combined surface area of the 1.8-inch drivers equivalent to a 22-inch driver. Each Kallsup also had its own 3-watt amplifier, resulting in a combined rated output of 447 watts for the entire wall.
While the wall was impressive, it didn't quite reach the world record of 1,500 speakers set by Majority Audio in March 2026. However, even at lower volumes, the collective Kallsup speakers sounded surprisingly competent, though their lack of depth and detail became apparent. When compared to the $500 LG Xboom Stage 501, the Kallsup wall provided an equally ear-splitting volume but lacked the fuller, deeper bass and more musical experience of the LG model.
Despite the impressive feat, the experiment highlighted the limits of the Kallsup chaining capacity. As the reporters linked more than 100 speakers, the likelihood of speakers failing to chain on the first attempt increased.
