Sonox X100 Floorstanding Speaker, Light Grey (Pair)

The Sonox X100 is a slim, fabric-wrapped floorstanding speaker (sound column) with a sealed Acoustic Suspension enclosure that reaches down to 29 Hz.

Developed by the Swiss manufacturer ROWEN, the X Series combines lifestyle design with genuine HiFi sound – the titanium-coloured "X"-shaped metal foot elegantly lifts the column off the floor.

Why the Sonox X100?

The sealed subwoofer system with two woofers delivers particularly deep and precise bass without bass-reflex boom – so you're free to place the column wherever you like: in a corner, next to a cabinet, or in front of a window front. Up top, the 18mm ROWEN fabric dome resolves fine detail from 4,300 Hz, while below, an ultra-fast, wide-bandwidth bass/mid system delivers excellent spatial imaging. At 6 Ω and 89 dB, the X100 is easy to drive.

What you hear

A wide soundstage, clear voices, natural timbre and a powerful, well-defined deep bass down to 29 Hz – the slim column sounds a whole size bigger than it looks. The metal plate set into the fabric up top can be customised to your taste via the included aluminium covers in silver or bronze. The light grey finish blends especially discreetly into modern, bright living rooms.

Who is the Sonox X100 for?

For anyone who wants to combine lifestyle looks with serious sound and appreciates flexible placement. Straight talk: the X100 is a passive speaker, so you'll need an amplifier. And the coarsely woven fabric cover is deliberately lifestyle-oriented – if you're after a glossy, mirror-finish lacquer column, a different design will suit you better.

Our verdict

An elegant, sonically mature column with character and flexible placement – lifestyle that actually sounds good.

Frequently asked questions

Do I need an amplifier for the Sonox X100?
Yes. The X100 is a passive floorstanding speaker and needs an integrated or streaming amplifier. At 6 Ω and 89 dB it's easy to drive and runs cleanly on most amplifiers. We're happy to work out the right power with you.

Where can I place the X100?
Almost anywhere. Thanks to the sealed enclosure, the bass stays precise rather than booming even in a corner, next to a cabinet, or in front of a window front. That makes placement very uncomplicated.

Can I customise the look?
Yes. The metal plate on top can be swapped using the included aluminium covers in silver or bronze. That lets you add a silver or bronze accent depending on your décor.
