NODE Audio wows with high-end ATOM loudspeaker range

Cambridge-based NODE Audio is looking to carve itself a significant slice of the crowded high-end loudspeaker market with the launch of its ATOM range, comprising the ATOM 525 standmount and ATOM 650 floorstander.

Production models of the newcomers made their public debut at the Audio Show Deluxe 2026, held at Whittlebury Park. The range is available to order now, with the company signalling an expansion of its distribution network.

Central to the design of the ATOM is a sculpted cabinet form that avoids flat panels and sharp edges, with the aim of reducing diffraction and maintaining stereo imaging.

Driver integration is also noteworthy. Tweeter and midrange units are positioned in close proximity to support phase coherence and consistent dispersion across the listening area. Low-frequency performance is handled by NODE’s proprietary Helical Transmission Line (HTL) system, last seen in the brand’s Hylixa model, which channels rear driver energy through a controlled internal pathway to extend bass response while maintaining control.

Internally, NODE has implemented a MonoCell structural damping system. Rather than using conventional damping materials, this employs a rigid internal lattice structure that provides both bracing and vibration control, with the intention of reducing cabinet colouration.

The range also introduces spiderless midrange drivers in a dual configuration. By removing the traditional suspension element and distributing the workload across two units, NODE says it can reduce mechanical resistance and improve responsiveness at lower signal levels.

Cabinets are finished in either multi-layer acoustic fabric or a selection of seven leather options, paired with precision-machined aluminium structural components.

The ATOM 525 is a compact three-way standmount design, using a 5.25-inch long-throw paper cone woofer, dual 2-inch magnesium alloy midrange drivers and a 0.85-inch neodymium soft dome tweeter. The crossover is set at 250Hz and 2.75kHz.

Specified bandwidth is 34Hz to 27kHz (-3dB), with sensitivity rated at 84dB (2.83V/1m) and a nominal impedance of 4 ohms. Maximum output is quoted at 103dB.

The enclosure measures 420mm high, 260mm wide and 390mm deep, with a weight of 13.7kg per speaker. The optional plinth is designed to complement the cabinet both visually and mechanically, supporting installation in high-end residential environments where space may be limited.

The larger ATOM 650 extends the same design approach into a floorstanding format. It retains the three-way configuration, with a larger 6.5-inch long-throw woofer, alongside the same dual 2-inch spiderless midrange drivers and 0.85-inch tweeter.

Frequency response is specified down to 28Hz (-3dB), offering greater low-frequency extension, while sensitivity increases to 86dB. Nominal impedance remains at 4 ohms, and maximum output is rated at 105dB.

The cabinet stands 978mm tall, with a width of 260mm and depth of 438mm, and weighs a substantial 21.7kg per unit. As with the 525, the enclosure construction and finish options are consistent across the range, allowing for a uniform aesthetic in multi-room or whole-home installations.

Retail pricing for the ATOM 525 standmount loudspeaker starts at £15,800, while the ATOM 650 floorstander is priced from £20,950.
