Remove the stress of stand selection by choosing Nelson – the ultimate Harbeth stand.

Power with control

With the sub-level control, the listener can adjust the bass up and down to suit personal preference, listening material and room characteristics.

A smart approach

Each speaker in the XD2 series incorporates a newly refined crossover design. The result is a speaker that not only excels in tonal accuracy but also offers greater depth and clarity, immersing listeners in a more lifelike musical experience.

Material Science

Inspired by the aviation industry, Nelson features the latest composite materials, providing high stiffness with low mass.

Overall Score 83/100

Nicely Roasted

The Nelson pairs a discrete 110mm bandpass woofer and 50W Class-D amp to give small standmounts a controlled, extended low end, delivering tight bass and DSP-matched integration while also serving as a tidy speaker stand. Reviewers at SoundStage Solo and Alpha Audio note its seamless blend with BBC-style monitors.

Alpha Audio

"Inside, in fact, is an invisible subwoofer, designed specifically to provide a certain kind of speaker with sufficient bass."

Pros

Purpose-built low-frequency reinforcement: 110mm bandpass driver, 50W amp and DSP deliver controlled extension down to the mid-30Hz region tailored for small monitors.
Seamless integration with Harbeth/ BBC-style monitors: designed and DSP-matched for the PS3ESR and LS3/5a family to achieve a natural crossover and correct listening height.
Thoughtful, compact stand design and finish: lightweight yet sturdy, black finish and neat speaker mounting deliver a unified, attractive setup.

Cons

Premium, niche price and positioning — cost is comparatively high and mainly justified for Harbeth/ BBC-style monitor owners.
Limited headroom for large rooms — designed for small-monitor reinforcement rather than reference-level low-frequency output in big spaces.

Bass

84/100

Reviews describe an "invisible subwoofer" tailored to give small monitors sufficient bass and list a 30–75Hz (spec) / 35–75Hz (review) range. The bandpass enclosure and dedicated 110mm driver yield solid extension and purpose-built low-end for BBC-style small monitors, though reviewers imply the output is sized for matching small speakers rather than large-room reference performance.

Dynamics

78/100

With a 50W built-in amplifier and bandpass design, the Nelson is described as providing adequate bass reinforcement for small monitors; reviewers imply competent punch and controlled output for its role. There is no explicit mention of extreme headroom or reference-level slam, so dynamics are rated as capable but not reference-class.

Integration

86/100

The reviewer states the Nelson is "perfectly matched to the included Harbeth PS3ESR XD" and calls it "perfect for getting those little speakers to ear level," which is outcome language showing good real-world blend with its intended speakers. DSP matching and a speaker-mounted connection help achieve the seamless result for BBC/LS3/5a-style monitors.

Build Quality

88/100

Reviewer notes the lightweight 7.6kg construction, tasteful black finish, and that the speakers "fit perfectly on the stand giving you a uniform look." The stand/sub appears well finished and thoughtfully integrated with Harbeth monitors, suggesting good cabinet and cosmetic quality.

Features Connectivity

82/100

Includes a 50W built-in amplifier, DSP application for matching ( presets for PS3ESR XD ), and a fitted lead that connects to the host loudspeaker binding posts. These practical tools make setup straightforward for Harbeth speakers and other BBC-style monitors, though connectivity is purpose-specific rather than broadly flexible.

Value for Money

74/100

Price is high and no review explicitly calls the Nelson a "no-brainer" or "best in class." Reviewers praise its specific effectiveness for Harbeth small monitors, which supports reasonable value within that niche but not a universal high-value claim.
