About Zenthesia
I built the bed I couldn’t buy. Then people kept asking for one.
A vibroacoustic bed lets you feel sound through your whole body. A high-fidelity bed lets you feel the texture that gives music its character. I built my first one for myself in Austin, Texas.
Thousands of people have felt it. Hundreds of beds shipped. My friend Cam and I still build each one by hand.
Hi, I’m Dave.
Both of my parents are electrical engineers. My dad built his own hi-fi sound system and speaker components, so I grew up around good sound, tools, and people who liked figuring out how things worked.
As a kid, I had an extensive vinyl record collection and assembled my own stereo systems from trips to Goodwill. Later, I installed a replacement audio system in my first car. I never expected that upbringing to lead to a company making sound therapy beds. I was looking for something for myself.
The music that started it
A difficult stretch with my physical and mental health led me to explore biohacking and, in 2019, to move to Austin.
Soon after arriving, I got a miniature Australian shepherd named Milo. He was my best bud, and we were inseparable. In February 2020, he was hit by a car in front of me. Losing him left me devastated.
Ketamine therapy helped me work through that loss, and music became central to those sessions. One track in particular, THE EGREGORE by LIGHTCODE, moved me so deeply that I began to see music as part of my own healing.
I already knew the physical pull of a good sound system from years of going to festivals and shows. I was always drawn to bass music and the feeling of the sub. Now I wanted to bring that feeling into a space where I could lie down, close my eyes, and be fully inside the music.
I wanted to feel that track with my whole body and receive it on a cellular level.
The first bed
I spent a year and a half looking for a vibroacoustic bed. I tried beds, asked questions, and looked for the combination of power, range, freedom, and fidelity I had in mind. I also wanted to know exactly what I was buying. Finding clear information about the hardware was nearly impossible.
Vibroacoustic therapy has been around for more than forty years. But the beds I found were still built on the same formula: low-cost bass shakers and basic amplifiers. I wanted to see this technology at its full potential, with a high-fidelity signal chain and the best components available, end to end.
I couldn’t find anything that brought it all together.
So I built my own.
I never meant to build more than the one for myself. But the first sessions made me want to share the experience. My friend Cam was so impressed that he asked me to build him one too. He became my first “customer,” paying me the cost of the parts and tickets to see ODESZA together. Then came invitations to bring it to events, and more people asking for one.
In 2022, I started building beds alongside a full-time job. In a full-circle moment, Cam and I were invited to run live sound through the beds for ODESZA’s show at The Concourse Project in December 2025.
Today, sharing the Zenthesia experience is the only thing I do.
Where the name came from
The name came to me during a session on the bed. I felt deeply calm, and I was so absorbed in the music that I began having closed-eye visuals from sound and vibration alone.
Zenthesia brings together the stillness of Zen with synesthesia, when separate senses blend into each other.
It is a name for the experience that made me want to share the bed in the first place.
What I’m here to do
I never set out to start a business. I set out to feel music the way I knew it could be felt.
My work is sharing that experience at the standard I hold for myself, and telling you exactly what you’re buying.
“This may not matter to others, yet it was the deciding factor for us: we chose Zenthesia over the other sound therapy beds because of Dave.”

Four things I wanted to get right
The priorities behind that first bed still guide what I build today. I’ve kept improving the build ever since, and the Sound Therapy Bed 2 is the result.
-
Power
I wanted enough power to feel fully immersed, with control over the intensity. Some sessions call for a gentle pulse. Others call for the physical presence I love at a live show.
-
Range
I wanted a broad frequency range so I could explore dedicated vibroacoustic tones and feel more of the music I loved, from deep bass to finer textures.
-
Freedom
That first LIGHTCODE track mattered to me. Your music should be just as welcome. You can play your own library through the bed, choose a streaming service, or use the Zenthesia app.
-
Fidelity
A drum hit, a bass line, and a sustained tone each have their own character. I wanted to preserve that character in the vibration, so the music would remain the focus.
Every component has a name
What I build is a step above everything else you’ll find on the market. I name my components because I’m not cutting corners or settling for less than the best. I use what delivers the best experience, and I can explain why.
A vibroacoustic bed is a sound system. Its tactile transducers turn the audio signal into physical vibration, and the components deserve the same attention you would give a good stereo. No one would spend thousands of dollars on a sound system without knowing exactly what they are getting. So every component below is a named product, and you can check each one against its maker’s published specifications instead of taking my word for it.
| Component | What I use in the Sound Therapy Bed 2 |
|---|---|
| Main amplifier | Crown XLS 1502 (maker’s specifications, opens in a new tab) |
| Tactile transducers | Four Shed Audio SA2-HFT150 units (maker’s specifications, opens in a new tab) |
| Headphone amplifier | JDS Labs Atom Amp 2 (maker’s specifications, opens in a new tab) |
| Headphones | Sennheiser HD 280 PRO (maker’s specifications, opens in a new tab) |
| Audio streamer | WiiM Mini (maker’s specifications, opens in a new tab) |
These five components are the signal chain. They are not the bed. Anyone can buy them, and I’d rather you know that than wonder. I’ve spent years perfecting the design around them: where the four transducers sit, how they’re mounted, and the frame and foam that carry the vibration for complete full-body immersion. That is the difference you feel.
Every bed arrives complete and ready to use, with the hardwood bed itself, cables, weighted blanket, pillow, eye mask, cover, and carry bags. Cam and I assemble and test each one by hand in Austin, and we sign the inside before it’s closed up. It comes with one two-year warranty for the whole system, a 45-day money-back guarantee, lifetime access to the Zenthesia app, and me on the other end of the phone.
If you’d rather build your own, I respect that. I sell the same transducers I use on their own, imported from Sheffield, England, and handpicked after testing as many as I could.
“When I compared different beds, I appreciated that the owner, Dave, was forthright with his specifications. You knew exactly what you were investing in.”
Music made to be felt
Building the bed also gave me the chance to work with artists on music created for it.
That work is part of the Zenthesia app: a growing library of lossless music, guided sessions, and breathwork. It brings together tracks composed for the bed and curated work from artists I love.
Lifetime access comes with every bed. You can use the app alongside your own music and favorite streaming services.
Light, sound, and vibration
The Cyberdelic combination
After exploring many ceremonies and plant medicines, I became deeply interested in how I could reach those introspective and visionary states without taking anything.
Alongside my interest in vibroacoustics, I began exploring stroboscopic light: systems that use pulsed light frequencies for neural entrainment and consciousness exploration.
I held stroboscopic lamps to the same standard as the beds. I wanted the best, and I tried many. The roXiva RX1 met that standard. I bought one for my own use first, and I’m honored to now be partnered with roXiva.
Used alongside the bed, it took the closed-eye visuals even further. With light, sound, and vibration together, I had found exactly what I was looking for. I call it the Cyberdelic combination: the closest thing to a psychedelic experience I have found without taking anything.
“The Zenthesia Vibroacoustic Sound bed paired with the RoXiva Light is a truly one of a kind, all-immersive experience.”

It ends up in more places than I ever imagined.
I built the first bed for one music lover: me. Today the beds are bought, used, and trusted by people I never pictured when I started.

Retreats
Several beds can play the same audio at once for a shared session.
They come for different reasons and choose it for the same one: it delivers a far more immersive and powerful experience than traditional vibroacoustic devices. Clinic, studio, or living room, the use case doesn’t change that. They simply want the highest-performing bed they can find.
Opening a practice, running a retreat, or planning an event? The bed folds and travels in its carry bags. Tell me what you have in mind.
“I’ve tried other sound beds before, but this one truly stands out. It’s not just vibration, it creates a deep meditative and relaxing experience that you really can’t put into words until you’ve had it yourself.”
You can reach the person who built it
I’m certified in vibroacoustic therapy through VibroacousticTherapy.com and as a breathwork instructor through Somatic Breathwork, and I’m the person building your bed. I care about the experience you have with it, from your first questions to the sessions you make part of your life.
If you need help getting set up, choosing music, or understanding a setting, you can come directly to me. That relationship continues after delivery.
I started by sharing something I loved with friends. That is still how I want this business to feel.
“The customer service hasn’t stopped since the bed has been delivered. He checks on me and makes sure everything is well and I am enjoying his product.”
As seen at
Come feel what started all of this
The experience makes more sense when you lie down and play a piece of music you love.
You can visit my Austin studio for a demo, find us at an event, or ask me about a place to try a bed closer to you.
Bring your questions. Pick a track. Let’s see what you think.
Try the bed in your own space. Every Sound Therapy Bed 2 comes with a 45-day money-back guarantee, a two-year warranty on the whole system, and direct support from me.
“We recently integrated two Zenthesia Sound Therapy Bed 2 units into our Psychotherapy & Wellness Center, and the response from clients has been exceptional.”
I build every bed to the standard I wanted for myself. Sharing it is still the best part.
