Stealth Invisible Speakers

FidelityGlass™ Technology

At the heart of Stealth Acoustics products is the FidelityGlass™ radiating diaphragm. Stealth has developed the technology to generate high-quality, full-range sound energy via a proprietary diaphragm material which is bonded to a patented rigid frame creating a large acoustically active area surrounded by a stable mounting surface. This FidelityGlass™ technology allows the LineaResponse speakers to be invisibly installed in walls and ceilings. It allows the StingRay speakers to be completely water-tight for an outdoor speaker like no other. It is also the technology behind the built-in audio systems in each of the Stealth Patio Theater models.

“We Test Every Product We Make!”

Reliability is one of Stealth’s primary goals and their speakers and TV systems are designed for long-term use. By using high-end components, protection devices, and general over-provisioning of the specifications, their products last a lifetime.

Stealth Products Are:
  • Small batch, hand-built in the USA
  • Made from the highest quality designs and materials
  • Rigorously tested – 100% QC

LineaResponse Invisible Speakers

Stealth’s LineaResponse LRX Series invisible speakers are the highest performing, best sounding invisible speakers on the market, ideal for home theater surround sound and ATMOS systems as well as stereo listening. Additionally, the LRg Series invisible speakers range from a 6” LR6g model perfect for whole-home and commercial audio to the popular and versatile 8” LR8g model. Completing the soundscape are two Bg Series invisible subwoofer systems for added bass response. — LineaResponse speakers are not just a hole-in-the-wall speaker with an “invisible” grille.


  • FidelityGlass™ flat radiating diaphragm technology
  • Extreme 170 degree sound dispersion
  • Patented combination of transducers & drivers
  • Traditional woofer driver in every speaker for excellent bass response
  • Smooth frequency extension
  • Protected from excessive input with self-resetting polyswitch circuits
  • Backed by a comprehensive warranty and an optional extended warranty that exceeds industry norms

What Is Invisibility?

For LineaResponse speakers the FidelityGlass™ radiating diaphragm technology is not only used for generating sound, but for its smooth, paintable surface which is the key to their invisibility. During installation, the speaker assembly is attached directly to the structural framing of a wall or ceiling. Standard wall finishing techniques are all that is necessary to render the speaker visually invisible. On-site finishing options include; latex paint, light wallpaper, fabrics, and selected texture coats. Level-5 finishes and other advanced finishing methods such as veneer treatments may be supported (contact Stealth Acoustics). —No speaker grills, no exposed drivers!

Besides visual invisibility, the FidelityGlass™ radiating diaphragm generates a 170 degree sound dispersion pattern eliminating the “flashlight effect” common with traditional speakers making the location of LineaResponse speakers “audibly invisible” with no identifiable sound source. Stealth speakers make the walls sing!

These two features combine to make LineaResponse speakers incredibly versatile. The speakers can easily be installed in locations where symmetrical speaker placement is not possible. A speaker location can be shifted to avoid structural obstacles or architectural elements of a room's design without any visible or audible imbalance.

The Industry’s First Invisible Under Eaves Speaker

In a 2020 CEPro survey on outdoor AV projects the number one industry requested product was for an invisible under eaves speaker - and Stealth Acoustics had it all along! The StingRay Soffit Speaker offers an under-eaves solution for high-quality outdoor audio without visual disruption to the architecture. Similar to a LineaResponse indoor speaker, once mounted flush with the soffit the pre-primed Soffit Speaker is ready for seam sealing and paint allowing it to become invisible against the surrounding soffit. — Replace ugly, rusted, conventional soffit speakers!

StingRay Soffit Speakers achieve aesthetic perfection without compromising audio quality

StingRay Outdoor Speakers

Creating great sounding outdoor speakers that can take on nature’s toughest elements is no easy task, but with the StingRay line of environmentally durable speakers and subwoofers, Stealth Acoustics has done just that!

StingRay high-performance outdoor speakers are based on a foundation of the LineaResponse indoor speakers capitalizing on the benefits of the FidelityGlass™ radiating diaphragm technology, which in this case also allows them to achieve an industry-leading IP68 waterproof rating. With a fully sealed design that prevents water, dust particles, and pests from getting inside and an operating temperature range of 0° – 150° F, StingRay speakers are at home in any climate.

StingRay outdoor speakers deliver smooth mid and high frequency response with a solid, rich bass extension and are ideal for luxury residential, commercial, and marine applications

Invisibility: Blend In! or Stand Out!

The sleek design and multiple mounting options mean StingRay speakers won’t be an eyesore and custom finishing options can further increase their concealment. A speaker can be painted to match the exterior finish of a building or the front radiating diaphragm of a StingRay speaker may be vinyl wrapped (on-site or custom ordered). Applying a photo of the surroundings can help conceal the speaker blending it into its background. Alternatively, a “hide in plain sight” approach can be taken and logos, branding graphics, or artwork can be applied for a unique audio solution.
