Breaking Update: Here’s a clear explanation of the latest developments related to Breaking News:I heard two new ‘invisible’ speakers that give new meaning to the idea of a ‘wall of sound’ — and they’re good enough that I’d use them for hi-fi or home theater– What Just Happened and why it matters right now.
In a world where speaker objets d’art exist such as the JBL L100 or B&O’s Beolab 90s, it’s always felt to me that if you’re lucky enough to own some high-end hi-fi speakers, they should be proudly on display in your home.
To that end, the notion of residential ‘invisible speakers’ always seemed like a solution to a problem that didn’t exist, in my mind. Installed in recesses behind walls or ceilings, allowing you to magically hear your music and movies without the speakers being in view at all, they perhaps made sense to me for commercial settings and places where floor space is at a premium — that’s why in-wall speakers are so popular in home theater installations — but otherwise the tech always came across as somewhat gimmicky.
Moreover, the examples I’d heard at audio and home theater shows often left me feeling flat (appropriately, I suppose), with anaemic outputs more reminiscent of the delivery you’d expect from a cheap soundbar than a home theater system.

Fast forward to 2026, and a visit to the ISE expo in Barcelona left me realizing that the game has very much changed, and not necessarily for the reasons you’d expect.
The luxury home-installation bracket is traditionally where hidden speakers reside, but two exhibitors at the show, each with a different approach to their hidden speakers, suggest you might be seeing — or not, as the case may be — more of these sound systems cropping up in more regular homes.
The first revelatory moment for me came with a visit to Amina’s stand. Based in Cambridge in the UK, the company is solely focused on its “plaster-over” invisible speakers, with its designs initially inspired by tech that first featured in the UK’s Ministry of Defence helicopter simulators from the 1980s.
Pride of place on the stand was an unassuming wall decorated with laminated wood behind which was housed three of the company’s latest larger Sapphire 375 75-watt speakers, coupled with one of its ALF 100 subwoofers, which had a vented port near the floor.
Listening to Van Morrison’s Days Like This through the system, I was taken aback by the full-bodied, yet controlled, crystal-clear delivery of the familiar song, coming from something that was, simply, a wall.
After moving around the wall, it soon occurred to me that the system appeared to have an unexpected advantage over a conventional speaker setup: there was no discernible ‘sweet spot’. No matter where I stood when facing the wall, there was still the same level of separation to the track’s instruments — whatever way the speakers were dispersing vibrations across the wall, it was allowing the 180-degree sound to fill the entire room in a uniform, consistent manner.
Advantages to an unusual approach
Speaking to Amina’s Managing Director Richard Newlove at the show , he explained how the design of Amina’s vibrational panel speakers takes influence from acoustic musical instruments, allowing them to create sound in a way that is more harmonious with their surroundings.
“A regular, moving-coil loud speaker is directional, so it’s only aiming in what direction the speakers are pointed. But when those reflections do come back, they start to interfere,” Richard explained.
“And in the worst-case scenario, what’s happening there is that you’re changing the sound in the room from what the speakers are creating. But acoustic musical instruments like violins send all frequencies in all directions, 360 degrees. The surface is creating a very complex energy wave, not a phase-related energy. A vibrational soundboard is better at connecting with air and putting sound into it. The beauty is that this way of dispersing sound is also scalable — a double bass and a violin work the same way.”
Amina’s early products were speakers disguised as pictures on walls, as well as ceiling tiles and projection screens, but they soon received requests for installs that were even more discreet, that could be recessed into the wall without any shadow line or gap, with those solutions evolving into what’s become its current speaker lineup.
The brand’s latest Sapphire range use super-lightweight honeycomb-structured panels that are driven by an electronic exciter, which delivers sound vibrations to the surface.
The panels are just 31mm thick and can be installed into a routed hole in stud walls or in plasterboard dry walls that can then be skimmed over, while their slim frame also enables them to work well behind panelled wood so long as the veneer isn’t too thick (anything over 2mm can degrade the output).
While early versions of vibration-based invisible speakers used a low-powered piezoelectric system to distribute sound and carbon panels that were too stiff to give out meaningful low frequencies, the improved materials and exciters being used in Amina’s Sapphire 375 speakers mean they’re able to deliver much greater midrange and bottom end with an impressive claimed frequency response of 50Hz to 20kHz.
Stealth mode
A short walk across the hall to American brand Stealth Acoustics shows a different, but no less impactful, approach to creating sound systems that disappear into their surroundings.
Based in Washington DC, the company has been producing invisible systems for the best part of 25 years, and is now on its eighth line of speakers with its LineaResponse X range. Unlike Amina’s vibrational panel approach, Stealth’s speakers uses a hybrid approach, combining traditional cone woofers with acoustic lever technologies for bass.
While that means that they’re more directional than Amina’s speakers, their flat front diaphragm design still means they deliver wide dispersion and also mean you don’t have to worry about symmetrical placement.
They do however, carry a lot more heft in output, both from a power perspective — up to a meaty 200 watts RMS with the new flagship L-RAD 430 speakers — as well as in terms of frequency response, with a much wider, deeper soundstage with a useable bass delivery down to ~35Hz.
Needing more depth and heavier in weight than Amina’s panels, Stealth’s LRX speakers are perhaps best suited to new construction projects where wooden studs are visible.
“The goal is to make a speaker that you go to first,” explains Stealth’s Business Development Director, Mark Cichowski. “Not to think, ‘I need an invisible speaker’, but more like, ‘I need a good-sounding speaker, and it is also invisible’.”
The permanence of hidden sound systems is also a consideration for Stealth, with Cichowski keen to stress its 20-year warranty. “Once it’s in the wall, there’s no maintenance — the failure rate is incredibly low. The systems themselves have circuit protection, so if someone goes and turns it up to 100, you’re not going to blow a speaker out and then have to dig it out of the wall and replace it. It’ll cap itself and tell the power to come back down.”
Some of the drawbacks that have always dogged invisible speakers, of course, still remain. While the costs have fallen since the early days of invisible speakers, that discreet elegance unsurprisingly still comes with a premium asking price, with Stealth’s L-RAD 430’s priced at $3,000 for a pair, while Amina’s Sapphire 375’s come in at a slightly more costly $1,800 per speaker — all before the installation costs.
While there’s always the option of fitting the speakers yourself, but much of the sound quality of both brand’s speakers is dependent on a quality install, so the two companies both advise using a professional service from their partners.
Once installed and finished over with plaster or paint, there’s then the issue of accessing them for service, upgrade or even if you want to remove them and take them with you should you move house — all scenarios that are considerably more difficult than with traditional visible speakers.
These factors aside, the tech has come far enough for invisible speakers to now become a real consideration for even discerning audiophiles. If you’re moving into a new place, or about to decorate your listening area, it might now be time to build your very own wall of sound.
