LineaRadiance LR30W
3-Way Flagship
“My name is Inigo Montoya. You thrilled my father. Prepare to buy.”
If you were trapped in a building on a desert island and could only install one invisible speaker pair, this would be it. The LR430 is the one of the flagship models of the series (along with the LR530) and the model for installations where invisible speakers are expected to deliver truly high-performance audio.
Designed for large spaces, demanding listening environments, and premium home cinemas, the LR430 produces expansive sound with powerful dynamics while remaining completely concealed within the architecture.
This is the speaker that proves invisible audio isn’t just about aesthetics, but rather about performance without compromise. The LR430 delivers room-filling sound, cinematic scale, and exceptional detail while maintaining the clean lines designers and architects demand.
It’s the invisible speaker that quietly (or not so quietly) says: “You can have world class audio without putting boxes all over the room.”
Highlights:
- A solution for cinematic audio
- 16” x 30” Footprint
- 8-Ohm, XXX-Watt RMS
LineaRadiance: Learn about Stealth's “Invisible Evolution” ⤵︎
LineaRadiance speakers represent the 8th generation evolution of Stealth Acoustics’ flat radiating diaphragm technology, first introduced in 2003 and continually refined for better performance, reliability, and installation simplicity.
Key features of the LineaRadiance family include:
AI in Speakers?
Our “AI” is Audio Intelligence™
Integrated acoustically tuned back box
Included with every speaker and removable when needed, because great sound deserves proper breathing room (even when it’s hiding in a wall).
Continually evolving transducer and exciter driver designs
Transducer? Exciter? Just give me great performance! We don’t sit on our hands and rest on what we’ve accomplished. Improved components mean greater efficiency and smoother sound, proof that invisible speakers are now a mainstream product, not a compromise.
Fidelity Glass Advanced™ tuned fiber diaphragm
Ooooooh, fancy name… The reality is that it is a patented (?), carefully engineered surface that balances stiffness and damping for clear, natural audio. It’s the part of the speaker that does all the talking… quietly.
Easy-Tape™ tapered frame and diaphragm
Designed to make drywall finishing easier for installers and completely seamless for the finished wall. After paint or wallpaper, the speaker simply vanishes like it was never there. Vanishes. Invisible. It’s like we have a theme here.
Higher power handling and re-voiced crossover networks
More control, more clarity, and better musical balance across the entire listening range. OK, that doesn’t mean that you should turn the volume to 11, but they do crank.
Increased diaphragm surface area on many models
Because sometimes the best way to improve sound is simply giving it more room to breathe.
Improved protection circuitry and poly-switches
Built-in safeguards keep the speaker operating reliably, even when someone decides the volume knob clearly goes past “reasonable.” Really, we talked about the turning it to “11” thing. Play nice with your equipment.
