The first clue that something unusual was happening at Supercarfest wasn't visual. It was bass.
Walking around Sywell Aerodrome in Northamptonshire, surrounded by the V8s, V12s, and W16s of the UK supercar community, you eventually caught a pocket of warm, properly-tuned low frequency coming from somewhere you couldn't immediately identify. The source turned out to be a pair of outdoor speakers playing chilled house music at civilised volume. They were the Steinway & Sons Marine loudspeakers, making their UK debut at the event — on hand courtesy of Steve Webber of the Danish Audio Company and supported by Charlie and Simon from Steinway Lyngdorf UK.
Zebra Home Cinema was there to cover it.
What the Steinway & Sons Marine Speakers Actually Are
Steinway & Sons' Marine range sits at the premium end of outdoor high-fidelity — speakers engineered for pool-deck, garden, terrace, and superyacht installation where weather exposure is a given and visual presentation still matters.
The specifications of the model at Supercarfest, in Webber's words:
- ▪Full-range reproduction in a single cabinet (no separate subwoofer required for most outdoor listening distances)
- ▪AMT (Air Motion Transformer) tweeter — a folded-ribbon high-frequency driver that delivers significantly faster transient response and lower distortion than a typical dome tweeter
- ▪Mid-range / mid-bass driver handling the vocal and instrumental register
- ▪Two 10-inch bass drivers on the rear of the cabinet — unusually large for an outdoor enclosure, and responsible for the warm low-end you heard before you saw the speaker
- ▪24-karat gold accents — the visual detailing that signals the Steinway co-branding rather than a generic weatherproofed outdoor box
"They're a full-range speaker. Obviously more familiar to superyacht owners — they're going to position them around the pool deck area, places like that, rather than a marquee on an aerodrome. But as you'd start with a product at the top of the range: 24-karat gold accents, AMT tweeter, mid-range, mid-bass, two nice big 10-inch bass drivers on the rear really do the business."
The physical presentation is substantial. These aren't the discreet cylindrical outdoor speakers you bury in a flower bed. They are architectural pieces designed to sit visibly and proudly in the space — appropriate for a pool-deck context where the outdoor loudspeaker is as much a design statement as the pool furniture.
What It Actually Costs
For a full working outdoor setup — one pair of Marine speakers, plus the Steinway Lyngdorf processor and amplification required to drive them correctly — the asking price is approximately £125,000 including VAT.
| Configuration | Approximate UK price (inc VAT) |
|---|---|
| 1 pair + processor + amplification | £125,000 |
| 2–5 pairs (scaled for larger spaces) | Linear scaling |
For context, Webber made the comparison directly with the cars surrounding the demo.
"For 125 grand, gorgeous stereo system outdoors — quite a bargain compared to some of the cars here. Compared to the Bugatti across the grass from us, dropping in the ocean."
A Bugatti Chiron lists north of £2.5 million. A full Marine system at £125,000 is, in that context, a quiet accessory.
The spec scales cleanly. A single pair covers a modest terrace or pool deck with genuine high-fidelity reach. Three, four, or five pairs — still driven by the appropriate processor and amplification — will cover a superyacht's upper deck, a large private garden, or a wraparound pool terrace without losing coherence at any listening position.
Where These Speakers Belong
The specified use-case for the Marine range is pool decks, superyacht upper decks, garden terraces, and outdoor entertainment spaces on significant residential properties. The conditions this product is engineered to survive:
- ▪Salt spray (the primary marine environment)
- ▪UV exposure
- ▪Rainfall and humidity
- ▪Temperature extremes
- ▪Direct sunlight on the driver surround and cabinet
Conventional indoor high-fidelity speakers fail all of these tests within a single season. A purpose-built marine speaker uses weather-resistant driver surrounds, UV-stable cabinet materials, stainless steel or marine-grade aluminium hardware, and sealed driver enclosures that will remain functional after years of weather exposure.
The Supercarfest deployment — under a marquee on an aerodrome rather than on a pool deck — was slightly off-brief, but it gave the UK audience the first chance to actually hear the speakers in a non-showroom context. The speakers were pulling people from elsewhere on the event site toward the marquee, which is the oldest reliable demonstration of what a loudspeaker is actually capable of.
How This Compares to Conventional Outdoor Speakers
Most outdoor loudspeakers — even the ones that cost several thousand pounds — are compromises. The weatherproofing comes at an acoustic cost. The driver size is constrained for weight or aesthetic reasons. The enclosure is compromised for flush-mounting convenience.
The Steinway & Sons Marine approach is the opposite: full-size cabinet, high-performance drivers (AMT tweeter, 10-inch rear-firing bass), weatherproofing layered on top of indoor-grade audio engineering. The cabinet stays above ground, proudly visible, rather than disguised as garden furniture.
| Typical outdoor speaker | Steinway & Sons Marine |
|---|---|
| Compromised for weight/aesthetics | Full-size audio-first cabinet |
| Dome tweeter | AMT (Air Motion Transformer) tweeter |
| Small bass drivers | 2× 10-inch rear-firing bass |
| Often flush-mount / hidden | Architectural, visible |
| Weatherproofing = acoustic compromise | Weatherproofing layered on indoor-grade engineering |
| Under £5,000 typical | ~£125,000 including processor & amp |
The positioning is unambiguous: this is the outdoor-audio equivalent of the reference indoor Steinway Lyngdorf range, pitched at clients whose outdoor entertainment areas are as considered as their indoor listening rooms.
Key Takeaways
- ▪The Steinway & Sons Marine outdoor loudspeakers made their UK debut at Supercarfest (Sywell Aerodrome, Northamptonshire), presented by Steve Webber of the Danish Audio Company and supported by Charlie and Simon from Steinway Lyngdorf UK.
- ▪Each speaker uses an AMT (Air Motion Transformer) tweeter, a mid-range / mid-bass driver, and two 10-inch rear-firing bass drivers in a full-range cabinet, with 24-karat gold accents as visual detailing.
- ▪A full working setup — one pair of Marine speakers plus the required Steinway Lyngdorf processor and amplification — is approximately £125,000 including UK VAT.
- ▪The range scales for larger spaces: three, four, or five pairs driven by scaled processing will cover a superyacht deck, a large private pool, or a wraparound terrace.
- ▪The engineering trade-off that separates the Marine range from conventional outdoor loudspeakers is that it does not compromise acoustic performance for weatherproofing. The cabinet is audio-first; the marine-grade protection is layered on top rather than replacing driver quality.
- ▪The deployment at Supercarfest was aesthetically off-brief (a marquee on an aerodrome rather than a pool deck), but acoustically demonstrative — the speakers pulled listeners from elsewhere on the event site toward the audio zone.
Frequently Asked Questions
What are the Steinway & Sons Marine speakers?
They are premium outdoor loudspeakers from Steinway Lyngdorf's marine range, designed for pool decks, garden terraces, and superyacht installation. Each cabinet includes an AMT tweeter, a mid-range / mid-bass driver, two 10-inch rear-firing bass drivers, and 24-karat gold visual accents. They are engineered to withstand salt spray, UV, humidity, and temperature extremes without the acoustic compromises typical of outdoor speakers.
How much do Steinway & Sons Marine speakers cost in the UK?
Approximately £125,000 including VAT for a single pair with the required Steinway Lyngdorf processor and amplification. Larger installations using multiple pairs scale linearly.
Where did the UK debut of these speakers happen?
At Supercarfest, Sywell Aerodrome, Northamptonshire. The speakers were presented by Steve Webber of the Danish Audio Company, with setup support from Charlie and Simon at Steinway Lyngdorf UK.
What makes an AMT tweeter different from a regular dome tweeter?
An Air Motion Transformer (AMT) tweeter uses a pleated/folded ribbon diaphragm that moves air via a squeezing motion, producing significantly faster transient response and lower distortion than a conventional dome tweeter of comparable size. It is one of the more distinctive engineering choices at the premium end of high-fidelity speaker design.
Can the Marine range be used indoors?
The Marine range is designed and optimised for outdoor deployment with full weatherproofing. It would function indoors but would be architecturally and aesthetically overspecified versus Steinway Lyngdorf's dedicated indoor reference ranges (such as the Model A, Model B, or Model D).
Who typically installs Steinway & Sons Marine speakers?
Clients with substantial outdoor entertainment spaces: superyachts, large private pool decks, significant residential gardens, and high-end outdoor venues. The specification assumes the outdoor area is treated with the same seriousness as the indoor listening room — a bracket of client that represents a small fraction of total outdoor-audio demand but a concentrated share of its spend.
