Singing Watermelons

Spherical Beamforming Arrays

A family of parametrically-designed spherical beamforming arrays built for space-first immersive sound. All share the same acoustic platform and workflows — from portable personal units to room-sculpting beasts — available built to order with matched amplification.

Flagship Highlights — Portable to Potent

Three battle-tested models that span the extremes — from airline carry-on portability to room-shaping power — covering most use cases while sharing the same approach and workflows. Each of our instruments comes with a matched Juicebox amp rack.

Perun24

24 × 6.5" drivers in 4-8-8-4 layout. Unparalelled spatial resolution and projection for large spaces, festivals, and installations. Extended low end below 50 Hz.

Svarog24

24 × 6" drivers in balanced 6-6-6-6 layout. A balanced resolution and projection in managable form — for most studio, performance, and venue applications.

The Rebel

16 × 2.5" drivers — our most compact and affordable model ideal for touring and mobile experimentation. It's our spin on Stefan Riedel's 3-9-3.

5.0" Range — The Nimble

Dazhbog is a solar deity, giver of wealth and sunlight in Slavic mythologies. These are portable instruments with their low end extending to about 75 Hz. Think of the violas in an orchestral setting.

6.0" Range — The Potent

Svarog is a god of celestial fire, blacksmithing, and creation. These are our firstborn instruments with low end extending to a bit below 60 Hz — closer to chellos in an orchestral setting.

Svarog 21

21 x 6" in 5-5-5-1 layout

Svarog 24

6.5" Range — The Supergods

Veles is the god of earth, waters, underworld, magic, and music. Perun — of thunder, lightning and sky. These are our largest and most powerful instruments, going below 50Hz. Think of a double bass family.

Even bigger?

We initially started with designs of 7.5" models. Then took a step back. Dare?

Juicebox Amps —
Matched portable racks

Compact, customizable multi-channel racks with DA conversion and amplification delivering clean power for beamforming, ambisonics, or multi-channel workflows as well as practical stage solutions.

FAQ

Price range

Pricing varies depending on configuration, channel count, and custom features. If you already have suitable interfaces, digital-to-analog converters, and amplifiers, this can further reduce the cost. Use our finder to identify the right instrument for you and reach out for a tailored quote.

Artist Prices?

Glad you asked. At the core of our mission is addressing barriers to access to spatial sound for artists. If you're buying as an individual, you might be eligible for "Artist Pricing". Please use our instrument finder to identify a suitable model, then — let's have a conversation.

Instrument weight and size?

The ‘Watermelons’ range between 25 to 60 cm in diameter and weights between 3 to 50 kg. The entire setup — including cases and amplifier racks — fit in 2-3 flightcases, depending on the model. Please use the Instrument Finder to narrow down your selection, we'll follow up with full specs.

Ordering Process

Instrument Selection + Meeting

Think of us as of the luthiers of 21st century — keeping it human and personal. Start with our Instrument Finder, then let's have a conversation about your practice and motivations for getting and using our instruments. We'll build a better understanding of your goals, and recommend a suitable configuration.

Customization

If your project falls out of our tested solutions, we'll discuss feasibility of customizations — from the number, layout and count of transducers, through build details, to control racks and software approach.

Build

Once your order is confirmed and paid, we'll start building an instrument for you. The lead time can be anything from 4 to 8 weeks, depending on configuration and a degree of customization.

Tuning

Once the build is complete, we measure and calibrate each instrument individually, providing a set of decoders and individual filters.

Delivery and training

The instruments can be picked up in person, or shipped. You'll get documentation in a digital format, with in-person and/or remote training. On-location training and workshops are available as a separate service.

Support

Custom coverage discussed during consultation. Lifetime calibration updates, workflow consulting, repair service. We're a small team — staying available means you enjoy the gear without headaches. Initial support period tailored to your needs.

Can I have a demo?

We provide opportunities to get to know and evaluate our technology in our Southwest Poland studio. You can book a visit or plan a residency with us. We also run spatial sound workshops at your venue — artists work hands-on with Watermelons. Contact to discuss current demo options or schedule visit. Hands-on experience beats specs.
