Raidho X1.6 Reference Finds Scale in Small Spaces

Handbuilt in Denmark, the new model is positioned as a more ambitious version of Raidho’s compact standmount design, aimed at listeners who want much of the speed and scale associated with the brand’s larger loudspeakers without moving into a full floorstanding footprint.

The most significant changes appear to sit inside the cabinet, with Raidho saying the X1.6 Reference uses a completely hand-built crossover populated with Mundorf components, alongside Nordost Valhalla technology cabling. Notably, that cabling is used not only within the loudspeaker but also inside the crossover itself, a level of internal attention more commonly associated with costlier high-end designs.

It is easy to skim past things like crossover parts and internal wiring, because they are not the bits you see from the listening chair. But they can still shape a loudspeaker in meaningful ways, from noise behaviour and signal flow to how naturally the drivers hand over to one another. With the X1.6 Reference, Raidho seems to be treating the crossover as part of the speaker’s voice, not just the necessary electronics hidden inside the box.

For the drive units, Raidho has stayed with its own hardware. The X1.6 Reference combines the company’s ribbon tweeter with a 6.5-inch ceramic/aluminium bass/midrange driver, both built in-house at its Danish factory. That tweeter lineage also featured prominently in Raidho’s recent X2t 25th Anniversary Edition, where the company highlighted its in-house planar-magnetic ribbon design.

That ribbon tweeter has long been tied to the company’s pursuit of speed and low-mass transparency, while the ceramic/aluminium mid-bass driver is intended to balance stiffness, control and responsiveness. That combination is designed to deliver the sort of openness and transient precision expected from a compact high-end monitor, but with greater authority than its size might suggest.

A rear-mounted passive radiator is another key part of the Reference update for the X1.6. Rather than relying purely on a conventional ported enclosure, Raidho says the passive radiator gives the speaker greater bass power and physical presence, pushing it closer to the scale of a small floorstanding loudspeaker.

The passive radiator is not being pitched simply as a bass-boosting device, but as a way of giving the speaker more ease and weight through the lower frequencies, allowing the midrange to breathe more naturally.

Morten Kim Nielsen, CEO of Raidho Acoustics, said the Reference version was created to show how far a compact loudspeaker could be taken when the supporting engineering was treated with the same seriousness as the drivers:

The original X1.6 already had a very strong musical identity. But with this Reference version, the improvements are substantial. The crossover, the internal cabling, the passive radiator and the in-house Raidho drivers all work together to create a speaker that sounds much bigger and more complete than its size suggests.

The cabinet design follows Raidho’s familiar Scandinavian visual language, with a clean and understated form rather than an overtly theatrical appearance. As ever with a loudspeaker at this level, the real question will be how effectively the engineering translates into coherence, scale and emotional engagement in the listening room.

The Raidho X1.6 Reference is priced at €10,000 per pair. Raidho is also introducing a dedicated Raidho / Scansonic loudspeaker stand, available in black or white, priced at €500 per pair and compatible with all Raidho and Scansonic compact speakers.

Both the speaker and stand will debut at HIGH END Vienna 2026, taking place from 4 to 7 June at Austria Center Vienna.
