• Eversolo has released the SE100 passive bookshelf speakers
• Hardware and specs fit for audiophiles
• They’re designed to fit in Ikea Kallax shelves

One of the loudspeaker standouts of annual tech jamboree CES 2026 has been the tiny $9.99 Ikea Kallsup, designed to be bought and used en masse. However, another brand’s new passive speakers show us what integration with Ikea furniture could really look like.

Audio hardware brand Eversolo has taken a rare foray into speakers, in the form of the brand-new SE100. These passive bookshelf speakers come in a pair so they are not, despite the brand’s name, forever on their own.

Eversolo generally sticks to hi-fi kit such as DACs (otherwise known as digital-analog converters), hi-res music players and amplifiers, and it’s clear that the SE100 continue the brand’s focus on kit for audiophiles. It’s specs include a 5.25-inch paper-pulp cone for textured sound, 25mm silk dome for clarity and a removable fabric grille that's designed for low diffraction, which means they should remain “acoustically invisible” according to Eversolo – although I'd rather take them off to see those glorious offset drivers. Something decidedly '1830s Daguerrotype camera' about them, no?

Judging by Eversolo’s product listing, another focus of the speakers is soundstage. While they’re wired and designed to be used alongside an amplifier, so can’t be spread out too far, they’re engineered to create a holographic soundstage in a range of spaces.

So far, so-fas (and other furniture) don’t seem relevant – so why was I talking about Ikea? Well, according to Eversolo, the SE100 are designed to fit seamlessly into the Ikea Kallax. If you’re not well versed in your Ikea lingo, these are those grid-style shelves that arrange things into boxes (see above). The SE100 fit perfectly into one of those boxes, without dead space around the sides.

Ikea has quite a few home-made speakers of its own now, ranging from standalone inexpensive shower-friendly Bluetooth boxes to options hidden in lamps, picture frames and lights. But as far as I can tell, Ikea has never released a set of speakers designed specifically to fit into the gaps in its furniture. The similarly named Kallsup, for example (don't get confused here – Kallax is the shelving unit; Kallsup are those little $10 cube speakers), are designed to be portable, not in-shelf fixtures.
