Introducing the S400 MK3
The S400 MK3 is a complete redesign with a larger cabinet, new drivers and improved dynamics - while keeping the balanced and natural sound the S400 series is known for.
S400 MK3 - A New Chapter for a Modern Classic
The S400 has been a cornerstone of our product lineup since its first prototype in 2016. It was also the first HiFi speaker developed using the Klippel Near Field Scanner (NFS), which at the time represented the cutting edge of acoustic measurement technology. This allowed us to develop a waveguide with unprecedented precision - a design that remains fundamental to many of our speakers today.
Combined with its compact cabinet and the innovative use of passive radiators, the original S400 quickly earned worldwide recognition as a small speaker capable of delivering unexpectedly powerful sound.
Over the years, the S400 became one of the most frequently recommended stand-mount speakers in the €2,000 - €3,000 class
When the S400 MK2 was introduced in 2021, it further refined the concept with an improved crossover and exceptionally high-quality components, strengthening its reputation for performance far beyond its price. But in loudspeaker design, perfection does not exist. Every product is a balance of priorities, and we continuously listen to feedback from both customers and reviewers.
One insight became clear: while the S400 was designed to deliver maximum performance from a very compact enclosure, many listeners comparing it to competitors were often considering speakers significantly larger in size. Another consistent request was even greater treble resolution and increased dynamic authority. The S400 MK3 is our answer to that feedback.
This new generation is a complete redesign, reusing only a single component from its predecessor - the binding posts.
Larger Cabinet, Greater Capability
The first noticeable change in the S400 MK3 is its size. The cabinet volume has increased by 18%, allowing us to push the performance envelope further while maintaining the elegant proportions of the original design.
At the heart of the new system is a 7.5-inch woofer, specifically the SB Acoustics Satori PAPYRUS™ paper cone driver providing a wopping 65.5% greater displacement headroom compared to the S400 MK2.
Rather than developing a proprietary driver hidden behind branding, we chose one of the finest commercially available drivers in the world. This decision reflects our philosophy of transparency and value: we want customers to clearly see the level of engineering and component quality that goes into our speakers.
Drivers of this caliber are typically found in high-end DIY builds or far more expensive speakers. Seeing one in a finished branded speaker at this price point does not exist today.
