High-End Audio Experience

You drive the world’s best electric car. You should be listening to the world’s best car stereo.

Our goal is to recreate the same authentic, rich sounds that were recorded in the artist’s studio and then replicate them in your car. To achieve this goal, we believe in creating new technologies, like our flagship Da Vinci DAC, that precisely reproduces even the most minute details of timbre that are lost on most audio systems. We use this same technology to bring you the most accurate pitch and intensity, the most powerful bass, and the most immersive listening experience available for Model S.

Seriously Deep Bass. Finally.

When will the bass drop? The answer is now.

Model S’ factory subwoofer leaves much to be desired. Using proprietary technology specifically designed for the Tesla Model S, four dedicated amplifiers pump up to 600 watts of continuous (1000 watts peak) power into our 8 inch subwoofer that fits directly into Tesla’s bass box. You’ll love the detail your new sub brings to a bass guitar and the deep impact you’ll feel when a kick drum hits.

Lightweight, Efficient Speakers

Our motors use ultra-efficient pure copper coils for super-fast performance.

Our speakers are fast. Ludicrous fast. Because we use hand-wound 99.9999% pure copper coils in all of our custom speaker motors. These coils are beautifully married to high-efficiency, lightweight rare earth permanent magnets. When energized, our coils resonate in perfect time to the music, achieving even greater detail that you’ve come to expect from the most expensive car audio systems.

Engineered Specifically for Model S

High-end cars like Model S should NOT use off-the-rack audio components.

We’ve tailor-made the perfect audio system for Model S, spending over a year testing, measuring, and refining every aspect of the audio system. From the smallest resistor to the largest voice coil, everything is custom made for your one-of-a-kind car. The result is the finest audio experience you can find in a Tesla anywhere.

Eight Core Digital Amplifier

Intuitive Class D amplification with Smart Power Management consumes less energy while providing 400% more power, on demand.

Tesla’s factory-installed power squandering Class A/B amplifier uses four power amp chips. Our efficient Class D power plant has eight and still uses less energy. This innovative design provides a firm bass foundation for its striking and inviting midrange tones. Its crisp, detailed highs provide a perfectly balanced punctuation to your music.

Your stereo shouldn’t be sucking away battery life when you’re not listening to it. So our amplifier powers up when it’s being used and powers down when it isn’t. And it does it all in a span of only 1/200,000th of a second.

Extend Your Range

In a car that values range as much as it values style, comfort, and performance, the audio system shouldn’t be power hungry.

We use an all-digital energy-efficient amplification design. It consumes 50% less energy, and wastes 91% less. When you crank it to 11, it delivers more than four times the power to the speakers than Model S’ factory installed amplifier.

Immersive Acoustic Technology

Few have actually experienced a truly immersive stereophonic experience.

Our amplifier improves the harmonic distortion tenfold over the factory offering, and lowers the entire audio system’s noise floor almost beyond our ability to measure– well beyond our ability to hear. These two improvements give you the sensation of a realistic three dimensional performance embracing you from every direction.

Going Green and Spending Less of It

Eco-friendly and budget conscious: two phrases you seldom see together.

Taking personal initiative to reduce your carbon footprint gives you a good feeling.  Accomplishing carbon reduction while saving money is an even better feeling. Our system gives you superior sound that’s much more efficient, costing you less to operate.

About Lightharmonic

They say we’re a bunch of smug, tech-happy audiophiles high on great sound with piles of gear that we swap in-and-out at every whim.

We’re not smug.

We’re like you; we love high-end audio gear, especially the kind of high-performance digital gear we make in Roseville, CA. In fact, we were the first company to tell the world, “24/192 doesn’t cut it. If you want digital audio to sound like its analog counterpart, you have to start at 32 bits and 384 kHz.”

We were laughed at for the first couple of years. We carried our 75 pound Da Vinci DAC to every trade show the world offered. Airlines hated us. Our chiropractors loved us. And once enough people had listened to our R2R groundbreaker, we were vindicated.

We’ve been featured in all the major audio industry publications and have even been featured in Forbes, The Wall Street Journal, and Entrepreneur. But we’re not letting it get to our head. Instead, we’ll keep plowing forward, blazing new trails, and coming up with some seriously awesome stuff.
