The Purified 4 Desktop is available in several variants with PURIFI 102mm mid/bass driver and BlieSMa 25mm tweeter. Every variant includes a crossover profile tuned for optimal tonal balance and the company claims the spherical-shaped mid/bass driver enclosure enables an exceptional linear on and off-axis response.

The Purified 4 Desktop is a modular active loudspeaker system designed to be driven with your own crossover and amplifiers or Sun Audio’s Plug & Play solution. The internal aluminium enclosure has been produced to reduce unwanted resonances while the external spherical shape is designed to ensure the most uniform radiation pattern. “As a result,” the company claims, “you get an exceptionally linear frequency response with razor-sharp imaging within a large soundstage. Furthermore, the ultra-low distortion drivers deliver an uncompressed, big and organic sound.” The Purified 4 is designed to be used as a satellite in a high-performance, full-range active sub-sat system. Available with a Purifi 102mm aluminium or fibre paper mix mid/bass driver and BlieSMa 25mm aluminium-magnesium or beryllium tweeter.

For each variant a measurement data set and reference crossover design (DSP parameters) are included in the delivery. As for the finishes, the top unit comes as hardwood or with a high-quality black plastic cover. For those who do not wish to configure a DSP crossover, the company’s DSP Integrated Amplifier with pre-installed DSP profile is offered. The Purified 4 Desktop is priced at £2,266.

The Atohm 9 is a “supersmall” 230mm passive subwoofer set featuring a sealed aluminium enclosure with an internal volume of only 8.5 litres. The sealed aluminium enclosures, with a depth of only 270mm, are ideally placed close to a wall for maximum room gain. In a typical room a -3dB @25Hz can be realised without EQ. In case you need more SPL capability, you can add another pair and stack them. Depending on the capacity of your amplifier, two to three units can be configured in parallel. The subwoofer is priced at £1,776.

And finally, there’s the Nord DSP-DAC NCAS500MP amplifier. This Hypex NCore integrated with onboard Hypex DSP engine and DAC is built in cooperation with UK-based Nord Acoustics. The DSP profile for the Purified 4 loudspeakers are pre-loaded to offer an easy-to-use, Plug-&-Play solution. The Nord DSP-DAC NCAS500MP’s connectivity includes both digital and analogue inputs, powered outputs for the tweeters and mid/bass drivers, plus subwoofer outputs (RCA). A remote control is included in the package and the amplifier is priced at £1,776.
