Reso 2: Turn Your Case Into a High Quality Speaker
Seamlessly transform any compatible plastic travel case, toolbox, or hard-shell luggage into a high-fidelity portable sound system with patent-pending design, 12+ hours of playback, Bluetooth 6.0, app tuning, built-in DSP, USB-C rechargeable, and no lost storage space. Check the demo video below.
Every audio brand has the same pitch: here's one more thing to pack?
Reso 2 is the first product to ask a different question: what if the case you're already carrying could be the speaker?
Patent-pending design mounts inside any plastic case you already own and turns the entire case into a boombox with stereo sound.

If it sounds this good through your screen
Imagine it in the room
38 watts of stereo audio, driven through the surface of your case lid. Check out the sound comparison below.
Don't Take Our Word For It
Most people hear "case lid speaker" and assume a compromise. So we put Reso 2 next to a dedicated hi-fi system and hit play. Judge it yourself.
Traditional speakers use a bulky frame and cone to move air and produce sound waves.
Reso 2 uses the same acoustic principle, but your case lid becomes the speaker frame and cone.
Two precision sound pucks mount inside the lid and vibrate the plastic surface to move air and produce sound. The body of the case acts as a speaker enclosure to provide surprising fidelity and rich, impactful bass. The larger the compatible case, the larger the acoustic surface, the bigger the sound.
High Output Stereo Sound, Tuned to Your Case
A powerful class-D stereo amplifier drives two sound pucks that send vibrations through the lid of your case, transforming it into one large speaker. With the lid closed, the body of the case acts as a resonance chamber, producing deep, rich bass regardless of what’s inside.
Custom sound profiles, calibrated to your exact case size and material through the Reso 2 app, deliver premium high-fidelity audio wherever you are.
At just over 1.5" thick, Reso 2 securely mounts to the flat inner surfaces of your case - consuming very little storage volume. Your gear stays exactly where it was. Your case layout doesn't change. The only difference is that the case you've been carrying for years is now a high-fidelity stereo speaker
Built for Long Days and Travel
Reso 2’s 44.4Wh lithium battery delivers 12+ hours of continuous playback on a single charge.

No tools. No drilling. No specialist required.
Reso 2 installs in minutes: pre-fitted adhesive, magnetic connectors, and a quick in-app calibration. Then connect via Bluetooth and play.
Every case resonates differently based on its size, shape, and material.
The free ExciteWave app guides you through setup and calibration using real-world acoustic data from your specific setup. Our proprietary software then creates and applies an optimized listening profile built specifically for your case.
Once calibrated, choose from built-in presets like Bass Boost, Jazz, Rock, and Classical, fine-tune your sound with a 10-band EQ, or use the presets in your favorite streaming app.
Link Multiple Cases. Create Your Own Sound Stage.
One Reso 2 turns your case into a speaker. Two or more turns your crew's entire loadout into a sound system.
Using Bluetooth Mesh and the app's Party Mode, link multiple units across every case in the group to control individual or combined volume and switch between stereo and party listening modes.
